What's The Definition Of The Medical Condition Cyclosporine?Clinical Pharmacology CLINICAL PHARMACOLOGY Cyclosporine is a potent immunosuppressive agent which in animals prolongs survival of allogeneic transplants involving skin, heart, kidney, pancreas, bone marrow, small intestine, and lung.
Cyclosporine has been demonstrated to suppress some humoral immunity and to a greater extent, cell-mediated reactions such as allograft rejection, delayed hypersensitivity, experimental allergic encephalomyelitis, Freund's adjuvant arthritis, and graft vs.
host disease in many animal species for a variety of organs.
Successful kidney, liver, and heart allogeneic transplants have been performed in man using cyclosporine.
The exact mechanism of action of cyclosporine is not known.
Experimental evidence suggests that the effectiveness of cyclosporine is due to specific and reversible inhibition of immunocompetent lymphocytes in the G0-or G1-phase of the cell cycle.
T-lymphocytes are preferentially inhibited.
The T-helper cell is the main target, although the T-suppressor cell may also be suppressed.
Cyclosporine also inhibits lymphokine production and release including interleukin-2 or T-cell growth factor (TCGF).
No functional effects on phagocytic (changes in enzyme secretions not altered, chemotactic migration of granulocytes, macrophage migration, carbon clearance in vivo) or tumor cells (growth rate, metastasis) can be detected in animals.
Cyclosporine does not cause bone marrow suppression in animal models or man.
The absorption of cyclosporine from the gastrointestinal tract is incomplete and variable.
Peak concentrations (Cmax) in blood and plasma are achieved at about 3.5 hours.
Cmax and area under the plasma or blood concentration/time curve (AUC) increase with the administered dose; for blood, the relationship is curvilinear (parabolic) between 0 and 1400 mg.
As determined by a specific assay, Cmax is approximately 1.0 ng/mL/mg of dose for plasma and 2.7 to 1.4 ng/mL/mg of dose for blood (for low to high doses).
Compared to an intravenous infusion, the absolute bioavailability of the oral solution is approximately 30% based upon the results in 2 patients.
The bioavailability of Sandimmune Soft Gelatin Capsules (cyclosporine capsules, USP) is equivalent to Sandimmune Oral Solution, (cyclosporine oral solution, USP).
Cyclosporine is distributed largely outside the blood volume.
In blood, the distribution is concentration dependent.
Approximately 33% to 47% is in plasma, 4% to 9% in lymphocytes, 5% to 12% in granulocytes, and 41% to 58% in erythrocytes.
At high concentrations, the uptake by leukocytes and erythrocytes becomes saturated.
In plasma, approximately 90% is bound to proteins, primarily lipoproteins.
The disposition of cyclosporine from blood is biphasic with a terminal half-life of approximately 19 hours (range: 10 to 27 hours).
Elimination is primarily biliary with only 6% of the dose excreted in the urine.
Cyclosporine is extensively metabolized but there is no major metabolic pathway.
Only 0.1% of the dose is excreted in the urine as unchanged drug.
Of 15 metabolites characterized in human urine, 9 have been assigned structures.
The major pathways consist of hydroxylation of the Cγ-carbon of 2 of the leucine residues, Cη-carbon hydroxylation, and cyclic ether formation (with oxidation of the double bond) in the side chain of the amino acid 3-hydroxyl-N,4-dimethyl-L-2-amino-6-octenoic acid and N-demethylation of N-methyl leucine residues.
Hydrolysis of the cyclic peptide chain or conjugation of the aforementioned metabolites do not appear to be important biotransformation pathways.
Specific Populations Renal Impairment In a study performed in 4 subjects with end-stage renal disease (creatinine clearance < 5mL/min), an intravenous infusion of 3.5 mg/kg of cyclosporine over 4 hours administered at the end of a hemodialysis session resulted in a mean volume of distribution (Vdss) of 3.49 L/kg and systemic clearance (CL) of 0.369 L/hr/kg.
This systemic CL (0.369 L/hr/kg) was approximately two thirds of the mean systemic CL (0.56 L/hr/kg) of cyclosporine in historical control subjects with normal renal function.
In 5 liver transplant patients, the mean clearance of cyclosporine on and off hemodialysis was 463 mL/min and 398 mL/min, respectively.
Less than 1% of the dose of cyclosporine was recovered in the dialysate.
Hepatic Impairment Cyclosporine is extensively metabolized by the liver.
Since severe hepatic impairment may result in significantly increased cyclosporine exposures, the dosage of cyclosporine may need to be reduced in these patients.
Clinical Pharmacology CLINICAL PHARMACOLOGY Mechanism Of Action Cyclosporine is an immunosuppressive agent when administered systemically.
In patients whose tear production is presumed to be suppressed due to ocular inflammation associated with keratoconjunctivitis sicca, cyclosporine emulsion is thought to act as a partial immunomodulator.
The exact mechanism of action is not known.
Pharmacokinetics Blood cyclosporine A concentrations were measured using a specific high pressure liquid chromatography-mass spectrometry assay.
Blood concentrations of cyclosporine, in all the samples collected, after topical administration of RESTASIS® 0.05%, twice daily, in humans for up to 12 months, were below the quantitation limit of 0.1 ng/mL.
There was no detectable drug accumulation in blood during 12 months of treatment with RESTASIS® ophthalmic emulsion.
Clinical Studies Four multicenter, randomized, adequate and well-controlled clinical studies were performed in approximately 1,200 patients with moderate to severe keratoconjunctivitis sicca.
RESTASIS® demonstrated statistically significant increases in Schirmer wetting of 10 mm versus vehicle at six months in patients whose tear production was presumed to be suppressed due to ocular inflammation.
This effect was seen in approximately 15% of RESTASIS® ophthalmic emulsion-treated patients versus approximately 5% of vehicle-treated patients.
Increased tear production was not seen in patients currently taking topical anti-inflammatory drugs or using punctal plugs.
No increase in bacterial or fungal ocular infections was reported following administration of RESTASIS®.

Cyclosporine also inhibits lymphokine production and release including interleukin-2.
No effects on phagocytic function (changes in enzyme secretions, chemotactic migration of granulocytes, macrophage migration, carbon clearance in vivo) have been detected in animals.
Cyclosporine does not cause bone marrow suppression in animal models or man.
Pharmacokinetics The immunosuppressive activity of cyclosporine is primarily due to parent drug.
Following oral administration, absorption of cyclosporine is incomplete.
The extent of absorption of cyclosporine is dependent on the individual patient, the patient population, and the formulation.
Elimination of cyclosporine is primarily biliary with only 6% of the dose (parent drug and metabolites) excreted in urine.
The disposition of cyclosporine from blood is generally biphasic, with a terminal half-life of approximately 8.4 hours (range 5-18 hours).
Following intravenous administration, the blood clearance of cyclosporine (assay: HPLC) is approximately 5-7 mL/min/kg in adult recipients of renal or liver allografts.
Blood cyclosporine clearance appears to be slightly slower in cardiac transplant patients.
The Neoral® Soft Gelatin Capsules (cyclosporine capsules, USP) MODIFIED and Neoral® Oral Solution (cyclosporine oral solution, USP) MODIFIED are bioequivalent.
Neoral® Oral Solution diluted with orange juice or apple juice is bioequivalent to Neoral Oral Solution diluted with water.
The effect of milk on the bioavailability of cyclosporine when administered as Neoral Oral Solution has not been evaluated.
The relationship between administered dose and exposure (area under the concentration versus time curve, AUC) is linear within the therapeutic dose range.
The intersubject variability (total, %CV) of cyclosporine exposure (AUC) when Neoral® or Sandimmune® is administered ranges from approximately 20% to 50% in renal transplant patients.
This intersubject variability contributes to the need for individualization of the dosing regimen for optimal therapy (see DOSAGE AND ADMINISTRATION).
Intrasubject variability of AUC in renal transplant recipients (%CV) was 9%-21% for Neoral® and 19%-26% for Sandimmune®.
In the same studies, intrasubject variability of trough concentrations (%CV) was 17%-30% for Neoral® and 16%-38% for Sandimmune®.
Absorption Neoral® has increased bioavailability compared to Sandimmune®.
The absolute bioavailability of cyclosporine administered as Sandimmune® is dependent on the patient population, estimated to be less than 10% in liver transplant patients and as great as 89% in some renal transplant patients.
The absolute bioavailability of cyclosporine administered as Neoral® has not been determined in adults.
In studies of renal transplant, rheumatoid arthritis and psoriasis patients, the mean cyclosporine AUC was approximately 20% to 50% greater and the peak blood cyclosporine concentration (Cmax) was approximately 40% to 106% greater following administration of Neoral® compared to following administration of Sandimmune®.
The dose normalized AUC in de novo liver transplant patients administered Neoral® 28 days after transplantation was 50% greater and Cmax was 90% greater than in those patients administered Sandimmune®.
AUC and Cmax are also increased (Neoral® relative to Sandimmune®) in heart transplant patients, but data are very limited.
Although the AUC and Cmax values are higher on Neoral® relative to Sandimmune®, the pre-dose trough concentrations (dose-normalized) are similar for the two formulations.
Following oral administration of Neoral®, the time to peak blood cyclosporine concentrations (Tmax) ranged from 1.5-2.0 hours.
The administration of food with Neoral® decreases the cyclosporine AUC and Cmax.
A high fat meal (669 kcal, 45 grams fat) consumed within one-half hour before Neoral® administration decreased the AUC by 13% and Cmax by 33%.
The effects of a low fat meal (667 kcal, 15 grams fat) were similar.
The effect of T-tube diversion of bile on the absorption of cyclosporine from Neoral® was investigated in eleven de novo liver transplant patients.
When the patients were administered Neoral® with and without T-tube diversion of bile, very little difference in absorption was observed, as measured by the change in maximal cyclosporine blood concentrations from pre-dose values with the T-tube closed relative to when it was open: 6.9 ± 41% (range -55% to 68%).

The steady state volume of distribution during intravenous dosing has been reported as 3-5 L/kg in solid organ transplant recipients.
In blood, the distribution is concentration dependent.
Approximately 33%-47% is in plasma, 4%-9% in lymphocytes, 5%-12% in granulocytes, and 41%-58% in erythrocytes.
At high concentrations, the binding capacity of leukocytes and erythrocytes becomes saturated.
In plasma, approximately 90% is bound to proteins, primarily lipoproteins.
Cyclosporine is excreted in human milk.
(See PRECAUTIONS, Nursing Mothers) Metabolism Cyclosporine is extensively metabolized by the cytochrome P-450 3A enzyme system in the liver, and to a lesser degree in the gastrointestinal tract, and the kidney.
The metabolism of cyclosporine can be altered by the co-administration of a variety of agents.
(See PRECAUTIONS: DRUG INTERACTIONS) At least 25 metabolites have been identified from human bile, feces, blood, and urine.
The biological activity of the metabolites and their contributions to toxicity are considerably less than those of the parent compound.
The major metabolites (M1, M9, and M4N) result from oxidation at the 1-beta, 9-gamma, and 4-N-demethylated positions, respectively.
At steady state following the oral administration of Sandimmune®, the mean AUCs for blood concentrations of M1, M9, and M4N are about 70%, 21%, and 7.5% of the AUC for blood cyclosporine concentrations, respectively.
Based on blood concentration data from stable renal transplant patients (13 patients administered Neoral® and Sandimmune® in a crossover study), and bile concentration data from de novo liver transplant patients (4 administered Neoral®, 3 administered Sandimmune®), the percentage of dose present as M1, M9, and M4N metabolites is similar when either Neoral® or Sandimmune® is administered.
Excretion Only 0.1% of a cyclosporine dose is excreted unchanged in the urine.
Elimination is primarily biliary with only 6% of the dose (parent drug and metabolites) excreted in the urine.
Neither dialysis nor renal failure alter cyclosporine clearance significantly.
Drug Interactions (See PRECAUTIONS: DRUG INTERACTIONS) When diclofenac or methotrexate was co-administered with cyclosporine in rheumatoid arthritis patients, the AUC of diclofenac and methotrexate, each was significantly increased.
(See PRECAUTIONS: DRUG INTERACTIONS) No clinically significant pharmacokinetic interactions occurred between cyclosporine and aspirin, ketoprofen, piroxicam, or indomethacin.
Special Populations Pediatric Population Pharmacokinetic data from pediatric patients administered Neoral® or Sandimmune® are very limited.
In 15 renal transplant patients aged 3-16 years, cyclosporine whole blood clearance after IV administration of Sandimmune® was 10.6 ± 3.7 mL/min/kg (assay: Cyclo-trac specific RIA).
In a study of 7 renal transplant patients aged 2-16, the cyclosporine clearance ranged from 9.8-15.5 mL/min/kg.
In 9 liver transplant patients aged 0.6-5.6 years, clearance was 9.3 ± 5.4 mL/min/kg (assay: HPLC).
In the pediatric population, Neoral® also demonstrates an increased bioavailability as compared to Sandimmune®.
In 7 liver de novo transplant patients aged 1.4-10 years, the absolute bioavailability of Neoral® was 43% (range 30%-68%) and for Sandimmune® in the same individuals absolute bioavailability was 28% (range 17%-42%).

Clinical Trials Rheumatoid Arthritis The effectiveness of Sandimmune® and Neoral® in the treatment of severe rheumatoid arthritis was evaluated in 5 clinical studies involving a total of 728 cyclosporine treated patients and 273 placebo treated patients.
A summary of the results is presented for the “responder” rates per treatment group, with a responder being defined as a patient having completed the trial with a 20% improvement in the tender and the swollen joint count and a 20% improvement in 2 of 4 of investigator global, patient global, disability, and erythrocyte sedimentation rates (ESR) for the Studies 651 and 652 and 3 of 5 of investigator global, patient global, disability, visual analog pain, and ESR for Studies 2008, 654 and 302.
Study 651 enrolled 264 patients with active rheumatoid arthritis with at least 20 involved joints, who had failed at least one major RA drug, using a 3:3:2 randomization to one of the following three groups: (1) cyclosporine dosed at 2.5-5 mg/kg/day, (2) methotrexate at 7.5-15 mg/week, or (3) placebo.
Treatment duration was 24 weeks.
The mean cyclosporine dose at the last visit was 3.1 mg/kg/day.
See Graph below.
Study 652 enrolled 250 patients with active RA with > 6 active painful or tender joints who had failed at least one major RA drug.
Patients were randomized using a 3:3:2 randomization to 1 of 3 treatment arms: (1) 1.5-5 mg/kg/day of cyclosporine, (2) 2.5-5 mg/kg/day of cyclosporine, and (3) placebo.
Treatment duration was 16 weeks.
The mean cyclosporine dose for group 2 at the last visit was 2.92 mg/kg/day.

Drug Description NEORAL® Soft Gelatin Capsules (cyclosporine) Capsules, USP Modified NEORAL® Oral Solution (cyclosporine) Oral Solution, USP Modified WARNING Only physicians experienced in management of systemic immunosuppressive therapy for the indicated disease should prescribe Neoral®.
At doses used in solid organ transplantation, only physicians experienced in immunosuppressive therapy and management of organ transplant recipients should prescribe Neoral®.
Patients receiving the drug should be managed in facilities equipped and staffed with adequate laboratory and supportive medical resources.
The physician responsible for maintenance therapy should have complete information requisite for the follow-up of the patient.
Neoral®, a systemic immunosuppressant, may increase the susceptibility to infection and the development of neoplasia.
In kidney, liver, and heart transplant patients Neoral® may be administered with other immunosuppressive agents.
Increased susceptibility to infection and the possible development of lymphoma and other neoplasms may result from the increase in the degree of immunosuppression in transplant patients.
Neoral® Soft Gelatin Capsules (cyclosporine capsules, USP) MODIFIED and Neoral® Oral Solution (cyclosporine oral solution, USP) MODIFIED have increased bioavailability in comparison to Sandimmune® Soft Gelatin Capsules (cyclosporine capsules, USP) and Sandimmune® Oral Solution (cyclosporine oral solution, USP).
Neoral® and Sandimmune® are not bioequivalent and cannot be used interchangeably without physician supervision.
For a given trough concentration, cyclosporine exposure will be greater with Neoral® than with Sandimmune®.
If a patient who is receiving exceptionally high doses of Sandimmune® is converted to Neoral®, particular caution should be exercised.
Cyclosporine blood concentrations should be monitored in transplant and rheumatoid arthritis patients taking Neoral® to avoid toxicity due to high concentrations.
Dose adjustments should be made in transplant patients to minimize possible organ rejection due to low concentrations.
Comparison of blood concentrations in the published literature with blood concentrations obtained using current assays must be done with detailed knowledge of the assay methods employed.
For Psoriasis Patients (See also BOXED WARNINGS above) Psoriasis patients previously treated with PUVA and to a lesser extent, methotrexate or other immunosuppressive agents, UVB, coal tar, or radiation therapy, are at an increased risk of developing skin malignancies when taking Neoral®.
Cyclosporine, the active ingredient in Neoral®, in recommended dosages, can cause systemic hypertension and nephrotoxicity.
The risk increases with increasing dose and duration of cyclosporine therapy.
Renal dysfunction, including structural kidney damage, is a potential consequence of cyclosporine, and therefore, renal function must be monitored during therapy.
DESCRIPTION Neoral® is an oral formulation of cyclosporine that immediately forms a microemulsion in an aqueous environment.
Cyclosporine, the active principle in Neoral®, is a cyclic polypeptide immunosuppressant agent consisting of 11 amino acids.
It is produced as a metabolite by the fungus species Beauveria nivea.

Indications & Dosage INDICATIONS Sandimmune (cyclosporine) is indicated for the prophylaxis of organ rejection in kidney, liver, and heart allogeneic transplants.
It is always to be used with adrenal corticosteroids.
The drug may also be used in the treatment of chronic rejection in patients previously treated with other immunosuppressive agents.
Because of the risk of anaphylaxis, Sandimmune Injection (cyclosporine injection, USP) should be reserved for patients who are unable to take the soft gelatin capsules or oral solution.
DOSAGE AND ADMINISTRATION Sandimmune Soft Gelatin Capsules (cyclosporine capsules, USP) and Sandimmune Oral Solution (cyclosporine oral solution, USP) Sandimmune Soft Gelatin Capsules (cyclosporine capsules, USP) and Sandimmune Oral Solution (cyclosporine oral solution, USP) have decreased bioavailability in comparison to Neoral Soft Gelatin Capsules (cyclosporine capsules, USP) MODIFIED and Neoral Oral Solution (cyclosporine oral solution, USP) MODIFIED.
Sandimmune and Neoral are not bioequivalent and cannot be used interchangeably without physician supervision.
The initial oral dose of Sandimmune (cyclosporine) should be given 4 to 12 hours prior to transplantation as a single dose of 15 mg/kg.
Although a daily single dose of 14 to 18 mg/kg was used in most clinical trials, few centers continue to use the highest dose, most favoring the lower end of the scale.
There is a trend towards use of even lower initial doses for renal transplantation in the ranges of 10 to 14 mg/kg/day.
The initial single daily dose is continued postoperatively for 1 to 2 weeks and then tapered by 5% per week to a maintenance dose of 5 to 10 mg/kg/day.
Some centers have successfully tapered the maintenance dose to as low as 3 mg/kg/day in selected renal transplant patients without an apparent rise in rejection rate.
(See Blood Concentration Monitoring, below) Specific Populations Renal Impairment Cyclosporine undergoes minimal renal elimination and its pharmacokinetics do not appear to be significantly altered in patients with end-stage renal disease who receive routine hemodialysis treatments (See CLINICAL PHARMACOLOGY).
However, due to its nephrotoxic potential (See WARNINGS), careful monitoring of renal function is recommended; cyclosporine dosage should be reduced if indicated.
(See WARNINGS AND PRECAUTIONS) Hepatic Impairment The clearance of cyclosporine may be significantly reduced in severe liver disease patients (See CLINICAL PHARMACOLOGY).
Dose reduction may be necessary in patients with severe liver impairment to maintain blood concentrations within the recommended target range.
(See WARNINGS AND PRECAUTIONS) Pediatrics In pediatric usage, the same dose and dosing regimen may be used as in adults although in several studies, children have required and tolerated higher doses than those used in adults.
Adjunct therapy with adrenal corticosteroids is recommended.
Different tapering dosage schedules of prednisone appear to achieve similar results.
A dosage schedule based on the patient's weight started with 2.0 mg/kg/day for the first 4 days tapered to 1.0 mg/kg/day by 1 week, 0.6 mg/kg/day by 2 weeks, 0.3 mg/kg/day by 1 month, and 0.15 mg/kg/day by 2 months and thereafter as a maintenance dose.
Another center started with an initial dose of 200 mg tapered by 40 mg/day until reaching 20 mg/day.
After 2 months at this dose, a further reduction to 10 mg/day was made.
Adjustments in dosage of prednisone must be made according to the clinical situation.
To make Sandimmune Oral Solution (cyclosporine oral solution, USP) more palatable, the oral solution may be diluted with milk, chocolate milk, or orange juice preferably at room temperature.
Patients should avoid switching diluents frequently.
Sandimmune Soft Gelatin Capsules and Oral Solution should be administered on a consistent schedule with regard to time of day and relation to meals.
Take the prescribed amount of Sandimmune (cyclosporine) from the container using the dosage syringe supplied after removal of the protective cover, and transfer the solution to a glass of milk, chocolate milk, or orange juice.
Stir well and drink at once.
Do not allow to stand before drinking.
It is best to use a glass container and rinse it with more diluent to ensure that the total dose is taken.
After use, replace the dosage syringe in the protective cover.
Do not rinse the dosage syringe with water or other cleaning agents either before or after use.
If the dosage syringe requires cleaning, it must be completely dry before resuming use.
Introduction of water into the product by any means will cause variation in dose.
Sandimmune® Injection (cyclosporine injection, USP) FOR INFUSION ONLY Note: Anaphylactic reactions have occurred with Sandimmune Injection (cyclosporine injection, USP).
(See WARNINGS) Patients unable to take Sandimmune Soft Gelatin Capsules or Oral Solution pre-or postoperatively may be treated with the intravenous (IV) concentrate.
Sandimmune Injection (cyclosporine injection, USP) is administered at 1/3 the oral dose.
The initial dose of Sandimmune Injection (cyclosporine injection, USP) should be given 4 to 12 hours prior to transplantation as a single intravenous dose of 5 to 6 mg/kg/day.
This daily single dose is continued postoperatively until the patient can tolerate the soft gelatin capsules or oral solution.
Patients should be switched to Sandimmune Soft Gelatin Capsules or Oral Solution as soon as possible after surgery.
In pediatric usage, the same dose and dosing regimen may be used, although higher doses may be required.
Adjunct steroid therapy is to be used.
(See aforementioned.) Immediately before use, the intravenous concentrate should be diluted 1 mL Sandimmune Injection (cyclosporine injection, USP) in 20 mL to 100 mL 0.9% Sodium Chloride Injection or 5% Dextrose Injection and given in a slow intravenous infusion over approximately 2 to 6 hours.
Diluted infusion solutions should be discarded after 24 hours.
The Cremophor® EL (polyoxyethylated castor oil) contained in the concentrate for intravenous infusion can cause phthalate stripping from PVC.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
Blood Concentration Monitoring Several study centers have found blood concentration monitoring of cyclosporine useful in patient management.
While no fixed relationships have yet been established, in one series of 375 consecutive cadaveric renal transplant recipients, dosage was adjusted to achieve specific whole blood 24-hour trough concentrations of 100 to 200 ng/mL as determined by high-pressure liquid chromatography (HPLC).
Of major importance to blood concentration analysis is the type of assay used.
The above concentrations are specific to the parent cyclosporine molecule and correlate directly to the new monoclonal specific radioimmunoassays (mRIA-sp).
Nonspecific assays are also available which detect the parent compound molecule and various of its metabolites.
Older studies often cited concentrations using a nonspecific assay which were roughly twice those of specific assays.
Assay results are not interchangeable and their use should be guided by their approved labeling.
If plasma specimens are employed, concentrations will vary with the temperature at the time of separation from whole blood.
Plasma concentrations may range from ½ to 1/5 of whole blood concentrations.
Refer to individual assay labeling for complete instructions.
In addition, Transplantation Proceedings (June 1990) contains position papers and a broad consensus generated at the Cyclosporine-Therapeutic Drug Monitoring conference that year.
Blood concentration monitoring is not a replacement for renal function monitoring or tissue biopsies.

Revised: 2017
Indications & Dosage INDICATIONS Kidney, Liver, and Heart Transplantation Neoral® is indicated for the prophylaxis of organ rejection in kidney, liver, and heart allogeneic transplants.
Neoral® has been used in combination with azathioprine and corticosteroids.
Rheumatoid Arthritis Neoral® is indicated for the treatment of patients with severe active, rheumatoid arthritis where the disease has not adequately responded to methotrexate.
Neoral® can be used in combination with methotrexate in rheumatoid arthritis patients who do not respond adequately to methotrexate alone.
Psoriasis Neoral® is indicated for the treatment of adult, nonimmunocompromised patients with severe (i.e., extensive and/or disabling), recalcitrant, plaque psoriasis who have failed to respond to at least one systemic therapy (eg., PUVA, retinoids, or methotrexate) or in patients for whom other systemic therapies are contraindicated, or cannot be tolerated.
While rebound rarely occurs, most patients will experience relapse with Neoral® as with other therapies upon cessation of treatment.
DOSAGE AND ADMINISTRATION Neoral® Soft Gelatin Capsules (cyclosporine capsules, USP) MODIFIED and Neoral® Oral Solution (cyclosporine oral solution, USP) MODIFIED Neoral® has increased bioavailability in comparison to Sandimmune®.
Neoral® and Sandimmune® are not bioequivalent and cannot be used interchangeably without physician supervision.
The daily dose of Neoral® should always be given in two divided doses (BID).
It is recommended that Neoral® be administered on a consistent schedule with regard to time of day and relation to meals.
Grapefruit and grapefruit juice affect metabolism, increasing blood concentration of cyclosporine, thus should be avoided.
Newly Transplanted Patients The initial oral dose of Neoral® can be given 4-12 hours prior to transplantation or be given postoperatively.
The initial dose of Neoral® varies depending on the transplanted organ and the other immunosuppressive agents included in the immunosuppressive protocol.
In newly transplanted patients, the initial oral dose of Neoral® is the same as the initial oral dose of Sandimmune®.
Suggested initial doses are available from the results of a 1994 survey of the use of Sandimmune® in US transplant centers.
The mean ± SD initial doses were 9 ± 3 mg/kg/day for renal transplant patients (75 centers), 8 ± 4 mg/kg/day for liver transplant patients (30 centers), and 7 ± 3 mg/kg/day for heart transplant patients (24 centers).
Total daily doses were divided into two equal daily doses.
The Neoral® dose is subsequently adjusted to achieve a pre-defined cyclosporine blood concentration.
(See Blood Concentration Monitoring in Transplant Patients, below) If cyclosporine trough blood concentrations are used, the target range is the same for Neoral® as for Sandimmune®.
Using the same trough concentration target range for Neoral® as for Sandimmune® results in greater cyclosporine exposure when Neoral® is administered.
(See Pharmacokinetics, Absorption) Dosing should be titrated based on clinical assessments of rejection and tolerability.
Lower Neoral® doses may be sufficient as maintenance therapy.
Adjunct therapy with adrenal corticosteroids is recommended initially.
Different tapering dosage schedules of prednisone appear to achieve similar results.
A representative dosage schedule based on the patient's weight started with 2.0 mg/kg/day for the first 4 days tapered to 1.0 mg/kg/day by 1 week, 0.6 mg/kg/day by 2 weeks, 0.3 mg/kg/day by 1 month, and 0.15 mg/kg/day by 2 months and thereafter as a maintenance dose.
Steroid doses may be further tapered on an individualized basis depending on status of patient and function of graft.
Adjustments in dosage of prednisone must be made according to the clinical situation.
Conversion from Sandimmune® to Neoral® in Transplant Patients In transplanted patients who are considered for conversion to Neoral® from Sandimmune®, Neoral® should be started with the same daily dose as was previously used with Sandimmune® (1:1 dose conversion).
The Neoral® dose should subsequently be adjusted to attain the pre-conversion cyclosporine blood trough concentration.
Using the same trough concentration target range for Neoral® as for Sandimmune® results in greater cyclosporine exposure when Neoral® is administered.
(See Pharmacokinetics, Absorption) Patients with suspected poor absorption of Sandimmune® require different dosing strategies.
(See Transplant Patients with Poor Absorption of Sandimmune®, below) In some patients, the increase in blood trough concentration is more pronounced and may be of clinical significance.
Until the blood trough concentration attains the pre-conversion value, it is strongly recommended that the cyclosporine blood trough concentration be monitored every 4 to 7 days after conversion to Neoral®.
In addition, clinical safety parameters such as serum creatinine and blood pressure should be monitored every two weeks during the first two months after conversion.
If the blood trough concentrations are outside the desired range and/or if the clinical safety parameters worsen, the dosage of Neoral® must be adjusted accordingly.
Transplant Patients with Poor Absorption of Sandimmune® Patients with lower than expected cyclosporine blood trough concentrations in relation to the oral dose of Sandimmune® may have poor or inconsistent absorption of cyclosporine from Sandimmune®.
After conversion to Neoral®, patients tend to have higher cyclosporine concentrations.
Due to the increase in bioavailability of cyclosporine following conversion to Neoral®, the cyclosporine blood trough concentration may exceed the target range.
Particular caution should be exercised when converting patients to Neoral® at doses greater than 10 mg/kg/day.
The dose of Neoral® should be titrated individually based on cyclosporine trough concentrations, tolerability, and clinical response.
In this population the cyclosporine blood trough concentration should be measured more frequently, at least twice a week (daily, if initial dose exceeds 10 mg/kg/day) until the concentration stabilizes within the desired range.
Rheumatoid Arthritis The initial dose of Neoral® is 2.5 mg/kg/day, taken twice daily as a divided (BID) oral dose.
Salicylates, nonsteroidal anti-inflammatory agents, and oral corticosteroids may be continued.
(See WARNINGS and PRECAUTIONS: DRUG INTERACTIONS) Onset of action generally occurs between 4 and 8 weeks.
If insufficient clinical benefit is seen and tolerability is good (including serum creatinine less than 30% above baseline), the dose may be increased by 0.5-0.75 mg/kg/day after 8 weeks and again after 12 weeks to a maximum of 4 mg/kg/day.
If no benefit is seen by 16 weeks of therapy, Neoral® therapy should be discontinued.
Dose decreases by 25%-50% should be made at any time to control adverse events, e.g., hypertension elevations in serum creatinine (30% above patient's pretreatment level) or clinically significant laboratory abnormalities.
(See WARNINGS and PRECAUTIONS) If dose reduction is not effective in controlling abnormalities or if the adverse event or abnormality is severe, Neoral® should be discontinued.
The same initial dose and dosage range should be used if Neoral® is combined with the recommended dose of methotrexate.
Most patients can be treated with Neoral® doses of 3 mg/kg/day or below when combined with methotrexate doses of up to 15 mg/week.
(See CLINICAL PHARMACOLOGY, Clinical Trials) There is limited long-term treatment data.
Recurrence of rheumatoid arthritis disease activity is generally apparent within 4 weeks after stopping cyclosporine.
Psoriasis The initial dose of Neoral® should be 2.5 mg/kg/day.
Neoral® should be taken twice daily, as a divided (1.25 mg/kg BID) oral dose.
Patients should be kept at that dose for at least 4 weeks, barring adverse events.
If significant clinical improvement has not occurred in patients by that time, the patient's dosage should be increased at 2-week intervals.
Based on patient response, dose increases of approximately 0.5 mg/kg/day should be made to a maximum of 4.0 mg/kg/day.
Dose decreases by 25%-50% should be made at any time to control adverse events, e.g., hypertension, elevations in serum creatinine ( ≥ 25% above the patient's pretreatment level), or clinically significant laboratory abnormalities.
If dose reduction is not effective in controlling abnormalities, or if the adverse event or abnormality is severe, Neoral® should be discontinued.
(See Special Monitoring of Psoriasis Patients) Patients generally show some improvement in the clinical manifestations of psoriasis in 2 weeks.
Satisfactory control and stabilization of the disease may take 12-16 weeks to achieve.
Results of a dosetitration clinical trial with Neoral® indicate that an improvement of psoriasis by 75% or more (based on PASI) was achieved in 51% of the patients after 8 weeks and in 79% of the patients after 16 weeks.
Treatment should be discontinued if satisfactory response cannot be achieved after 6 weeks at 4 mg/kg/day or the patient's maximum tolerated dose.
Once a patient is adequately controlled and appears stable the dose of Neoral® should be lowered, and the patient treated with the lowest dose that maintains an adequate response (this should not necessarily be total clearing of the patient).
In clinical trials, cyclosporine doses at the lower end of the recommended dosage range were effective in maintaining a satisfactory response in 60% of the patients.
Doses below 2.5 mg/kg/day may also be equally effective.
Upon stopping treatment with cyclosporine, relapse will occur in approximately 6 weeks (50% of the patients) to 16 weeks (75% of the patients).
In the majority of patients rebound does not occur after cessation of treatment with cyclosporine.
Thirteen cases of transformation of chronic plaque psoriasis to more severe forms of psoriasis have been reported.
There were 9 cases of pustular and 4 cases of erythrodermic psoriasis.
Long term experience with Neoral® in psoriasis patients is limited and continuous treatment for extended periods greater than one year is not recommended.
Alternation with other forms of treatment should be considered in the long term management of patients with this life long disease.
Neoral® Oral Solution (cyclosporine oral solution, USP) MODIFIED–Recommendations for Administration To make Neoral® Oral Solution (cyclosporine oral solution, USP) MODIFIED more palatable, it should be diluted with orange or apple juice that is at room temperature.
Patients should avoid switching diluents frequently.
Grapefruit juice affects metabolism of cyclosporine and should be avoided.
The combination of Neoral® solution with milk can be unpalatable.
The effect of milk on the bioavailability of cyclosporine when administered as Neoral Oral Solution has not been evaluated.
Take the prescribed amount of Neoral® Oral Solution (cyclosporine oral solution, USP) MODIFIED from the container using the dosing syringe supplied, after removal of the protective cover, and transfer the solution to a glass of orange or apple juice.
Stir well and drink at once.
Do not allow diluted oral solution to stand before drinking.
Use a glass container (not plastic).
Rinse the glass with more diluent to ensure that the total dose is consumed.
After use, dry the outside of the dosing syringe with a clean towel and replace the protective cover.
Do not rinse the dosing syringe with water or other cleaning agents.
If the syringe requires cleaning, it must be completely dry before resuming use.
Blood Concentration Monitoring in Transplant Patients Transplant centers have found blood concentration monitoring of cyclosporine to be an essential component of patient management.
Of importance to blood concentration analysis are the type of assay used, the transplanted organ, and other immunosuppressant agents being administered.
While no fixed relationship has been established, blood concentration monitoring may assist in the clinical evaluation of rejection and toxicity, dose adjustments, and the assessment of compliance.
Various assays have been used to measure blood concentrations of cyclosporine.
Older studies using a nonspecific assay often cited concentrations that were roughly twice those of the specific assays.
Therefore, comparison between concentrations in the published literature and an individual patient concentration using current assays must be made with detailed knowledge of the assay methods employed.
Current assay results are also not interchangeable and their use should be guided by their approved labeling.
A discussion of the different assay methods is contained in Annals of Clinical Biochemistry 1994;31:420-446.
While several assays and assay matrices are available, there is a consensus that parent-compound-specific assays correlate best with clinical events.
Of these, HPLC is the standard reference, but the monoclonal antibody RIAs and the monoclonal antibody FPIA offer sensitivity, reproducibility, and convenience.
Most clinicians base their monitoring on trough cyclosporine concentrations.
Applied Pharmacokinetics, Principles of Therapeutic Drug Monitoring (1992) contains a broad discussion of cyclosporine pharmacokinetics and drug monitoring techniques.
Blood concentration monitoring is not a replacement for renal function monitoring or tissue biopsies.

Overdosage & Contraindications OVERDOSE There is a minimal experience with overdosage.
Because of the slow absorption of Sandimmune Soft Gelatin Capsules or Oral Solution, forced emesis and gastric lavage would be of value up to 2 hours after administration.
Transient hepatotoxicity and nephrotoxicity may occur which should resolve following drug withdrawal.
Oral doses of cyclosporine up to 10 g (about 150 mg/kg) have been tolerated with relatively minor clinical consequences, such as vomiting, drowsiness, headache, tachycardia and, in a few patients, moderately severe, reversible impairment of renal function.
However, serious symptoms of intoxication have been reported following accidental parenteral overdosage with cyclosporine in premature neonates.
General supportive measures and symptomatic treatment should be followed in all cases of overdosage.
Sandimmune (cyclosporine) is not dialyzable to any great extent, nor is it cleared well by charcoal hemoperfusion.
The oral LD50 is 2329 mg/kg in mice, 1480 mg/kg in rats, and > 1000 mg/kg in rabbits.
The intravenous (IV) LD50 is 148 mg/kg in mice, 104 mg/kg in rats, and 46 mg/kg in rabbits.
CONTRAINDICATIONS Sandimmune Injection (cyclosporine injection, USP) is contraindicated in patients with a hypersensitivity to Sandimmune (cyclosporine) and/or Cremophor® EL (polyoxyethylated castor oil).
Overdosage & Contraindications OVERDOSE No information provided.
CONTRAINDICATIONS RESTASIS® is contraindicated in patients with known or suspected hypersensitivity to any of the ingredients in the formulation.
Overdosage & Contraindications OVERDOSE There is a minimal experience with cyclosporine overdosage.
Forced emesis and gastric lavage can be of value up to 2 hours after administration of Neoral®.
Transient hepatotoxicity and nephrotoxicity may occur which should resolve following drug withdrawal.
Oral doses of cyclosporine up to 10 g (about 150 mg/kg) have been tolerated with relatively minor clinical consequences, such as vomiting, drowsiness, headache, tachycardia and, in a few patients, moderately severe, reversible impairment of renal function.
However, serious symptoms of intoxication have been reported following accidental parenteral overdosage with cyclosporine in premature neonates.
General supportive measures and symptomatic treatment should be followed in all cases of overdosage.
Cyclosporine is not dialyzable to any great extent, nor is it cleared well by charcoal hemoperfusion.
The oral dosage at which half of experimental animals are estimated to die is 31 times, 39 times, and > 54 times the human maintenance dose for transplant patients (6mg/kg; corrections based on body surface area) in mice, rats, and rabbits.
CONTRAINDICATIONS General Neoral® is contraindicated in patients with a hypersensitivity to cyclosporine or to any of the ingredients of the formulation.
Rheumatoid Arthritis Rheumatoid arthritis patients with abnormal renal function, uncontrolled hypertension, or malignancies should not receive Neoral®.
Psoriasis Psoriasis patients who are treated with Neoral® should not receive concomitant PUVA or UVB therapy, methotrexate or other immunosuppressive agents, coal tar or radiation therapy.
Psoriasis patients with abnormal renal function, uncontrolled hypertension, or malignancies should not receive Neoral®.
Side Effects & Drug Interactions SIDE EFFECTS The principal adverse reactions of Sandimmune (cyclosporine) therapy are renal dysfunction, tremor, hirsutism, hypertension, and gum hyperplasia.
Hypertension Hypertension, which is usually mild to moderate, may occur in approximately 50% of patients following renal transplantation and in most cardiac transplant patients.
Glomerular Capillary Thrombosis Glomerular capillary thrombosis has been found in patients treated with cyclosporine and may progress to graft failure.
The pathologic changes resemble those seen in the hemolytic-uremic syndrome and include thrombosis of the renal microvasculature, with platelet-fibrin thrombi occluding glomerular capillaries and afferent arterioles, microangiopathic hemolytic anemia, thrombocytopenia, and decreased renal function.
Similar findings have been observed when other immunosuppressives have been employed post transplantation.
Hypomagnesemia Hypomagnesemia has been reported in some, but not all, patients exhibiting convulsions while on cyclosporine therapy.
Although magnesium-depletion studies in normal subjects suggest that hypomagnesemia is associated with neurologic disorders, multiple factors, including hypertension, high-dose methylprednisolone, hypocholesterolemia, and nephrotoxicity associated with high plasma concentrations of cyclosporine appear to be related to the neurological manifestations of cyclosporine toxicity.

In some cases, patients have been unable to continue cyclosporine, however, the final decision on treatment discontinuation should be made by the treating physician following the careful assessment of benefits versus risks.
Pain of Lower Extremities Isolated cases of pain of lower extremities have been reported in association with cyclosporine.
Pain of lower extremities has also been noted as part of Calcineurin-Inhibitor Induced Pain Syndrome (CIPS) as described in the literature.
DRUG INTERACTIONS Effect Of Drugs And Other Agents On Cyclosporine Pharmacokinetics And/Or Safety All of the individual drugs cited below are well substantiated to interact with cyclosporine.
In addition, concomitant use of nonsteroidal anti-inflammatory drugs (NSAIDs) with cyclosporine, particularly in the setting of dehydration, may potentiate renal dysfunction.
Caution should be exercised when using other drugs which are known to impair renal function.
(See WARNINGS, Nephrotoxicity) Drugs That May Potentiate Renal Dysfunction Antibiotics Antineoplastic Antifungals Anti- Inflammatory Drugs Gastrointestinal Agents Immunosuppressives Other Drugs ciprofloxacin melphalan amphotericin B azapropazon cimetidine tacrolimus fibric acid derivatives (e.g., bezafibrate, fenofibrate) gentamicin ketoconazole colchicine ranitidine methotrexate tobramycin diclofenac trimethoprim with sulfamethoxazole naproxen vancomycin sulindac During the concomitant use of a drug that may exhibit additive or synergistic renal impairment potential with cyclosporine, close monitoring of renal function (in particular serum creatinine) should be performed.
If a significant impairment of renal function occurs, reduction in the dosage of cyclosporine and/or coadministered drug or an alternative treatment should be considered.
Cyclosporine is extensively metabolized by CYP 3A isoenzymes, in particular CYP3A4, and is a substrate of the multidrug efflux transporter P-glycoprotein.
Various agents are known to either increase or decrease plasma or whole blood concentrations of cyclosporine usually by inhibition or induction of CYP3A4 or P-glycoprotein transporter or both.
Compounds that decrease cyclosporine absorption such as orlistat should be avoided.
Appropriate Sandimmune (cyclosporine) dosage adjustment to achieve the desired cyclosporine concentrations is essential when drugs that significantly alter cyclosporine concentrations are used concomitantly.
(See Blood Concentration Monitoring) Drugs That Increase Cyclosporine Concentrations Calcium Channel Blockers Antifungals Antibiotics Glucocorticoids Other Drugs diltiazem nicardipine verapamil fluconazole itraconazole ketoconazole voriconazole azithromycin clarithromycin erythromycin quinupristin/ dalfopristin methylprednisolone allopurinol amiodarone bromocriptine colchicine danazol imatinib metoclopramide nefazodone oral contraceptives HIV Protease inhibitors The HIV protease inhibitors (e.g., indinavir, nelfinavir, ritonavir, and saquinavir) are known to inhibit cytochrome P-450 3A and thus could potentially increase the concentrations of cyclosporine, however no formal studies of the interaction are available.
Care should be exercised when these drugs are administered concomitantly.
Grapefruit juice Grapefruit and grapefruit juice affect metabolism, increasing blood concentrations of cyclosporine, thus should be avoided.
Drugs/Dietary Supplements That Decrease Cyclosporine Concentrations Antibiotics Anticonvulsants Other Drugs /Dietary Supplements nafcillin rifampin carbamazepine oxcarbazepine phenobarbital phenytoin bosentan octreotide orlistat sulfinpyrazone terbinafine ticlopidine St.
John's Wort Bosentan Co-administration of bosentan (250 to 1000 mg every 12 hours based on tolerability) and cyclosporine (300 mg every 12 hours for 2 days then dosing to achieve a Cmin of 200 to 250 ng/mL) for 7 days in healthy subjects resulted in decreases in the cyclosporine mean dose-normalized AUC, Cmax, and trough concentration of approximately 50%, 30% and 60%, respectively, compared to when cyclosporine was given alone.
(See also Effect of Cyclosporine on the Pharmacokinetics and/or Safety of Other Drugs or Agents) Coadministration of cyclosporine with bosentan should be avoided.
Boceprevir Coadministration of boceprevir (800 mg three times daily for 7 days) and cyclosporine (100 mg single dose) in healthy subjects resulted in increases in the mean AUC and Cmax of cyclosporine approximately 2.7-fold and 2-fold, respectively, compared to when cyclosporine was given alone.
Telaprevir Coadministration of telaprevir (750 mg every 8 hours for 11 days) with cyclosporine (10 mg on day 8) in healthy subjects resulted in increases in the mean dose-normalized AUC and Cmax of cyclosporine approximately 4.5-fold and 1.3-fold, respectively, compared to when cyclosporine (100 mg single dose) was given alone.
St.
John's Wort There have been reports of a serious drug interaction between cyclosporine and the herbal dietary supplement, St.
John's Wort.
This interaction has been reported to produce a marked reduction in the blood concentrations of cyclosporine, resulting in subtherapeutic levels, rejection of transplanted organs, and graft loss.
Rifabutin Rifabutin is known to increase the metabolism of other drugs metabolized by the cytochrome P-450 system.
The interaction between rifabutin and cyclosporine has not been studied.
Care should be exercised when these two drugs are administered concomitantly.
Effect Of Cyclosporine On The Pharmacokinetics And/Or Safety Of Other Drugs Or Agents Cyclosporine is an inhibitor of CYP3A4 and of multiple drug efflux transporters (e.g., P-glycoprotein) and may increase plasma concentrations of comedications that are substrates of CYP3A4, Pglycoprotein, or organic anion transporter proteins.
Cyclosporine may reduce the clearance of digoxin, colchicine, prednisolone, HMG-CoA reductase inhibitors (statins) and aliskiren, bosentan, dabigatran, repaglinide, NSAIDs, sirolimus, etoposide, and other drugs.
See the full prescribing information of the other drug for further information and specific recommendations.
The decision on coadministration of cyclosporine with other drugs or agents should be made by the healthcare provider following the careful assessment of benefits and risks.
Digoxin Severe digitalis toxicity has been seen within days of starting cyclosporine in several patients taking digoxin.
If digoxin is used concurrently with cyclosporine, serum digoxin concentrations should be monitored.
Colchicine There are reports on the potential of cyclosporine to enhance the toxic effects of colchicine such as myopathy and neuropathy, especially in patients with renal dysfunction.
Concomitant administration of cyclosporine and colchicine results in significant increases in colchicine plasma concentrations.
If colchicine is used concurrently with cyclosporine, a reduction in the dosage of colchicine is recommended.
HMG Co-A Reductase Inhibitors (statins) Literature and postmarketing cases of myotoxicity, including muscle pain and weakness, myositis, and rhabdomyolysis, have been reported with concomitant administration of cyclosporine with lovastatin, simvastatin, atorvastatin, pravastatin, and rarely, fluvastatin.
When concurrently administered with cyclosporine, the dosage of these statins should be reduced according to label recommendations.
Statin therapy needs to be temporarily withheld or discontinued in patients with signs and symptoms of myopathy or those with risk factors predisposing to severe renal injury, including renal failure, secondary to rhabdomyolysis.
Repaglinide Cyclosporine may increase the plasma concentrations of repaglinide and thereby increase the risk of hypoglycemia.
In 12 healthy male subjects who received two doses of 100 mg cyclosporine capsule orally 12 hours apart with a single dose of 0.25 mg repaglinide tablet (one half of a 0.5 mg tablet) orally 13 hours after the cyclosporine initial dose, the repaglinide mean Cmax and AUC were increased 1.8 fold (range: 0.6 to 3.7 fold) and 2.4 fold (range 1.2 to 5.3 fold), respectively.
Close monitoring of blood glucose level is advisable for a patient taking cyclosporine and repaglinide concomitantly.
Ambrisentan Coadministration of ambrisentan (5 mg daily) and cyclosporine (100 to 150 mg twice daily initially, then dosing to achieve Cmin 150 to 200 ng/mL) for 8 days in healthy subjects resulted mean increases in ambrisentan AUC and Cmax of approximately 2-fold and 1.5-fold, respectively, compared to ambrisentan alone.
When coadministering ambrisentan with cyclosporine, the ambrisentan dose should not be titrated to the recommended maximum daily dose.
Anthracycline Antibiotics High doses of cyclosporine (e.g., at starting intravenous dose of 16 mg/kg/day) may increase the exposure to anthracycline antibiotics (e.g., doxorubicin, mitoxantrone, daunorubicin) in cancer patients.
Aliskiren Cyclosporine alters the pharmacokinetics of aliskiren, a substrate of P-glycoprotein and CYP3A4.
In 14 healthy subjects who received concomitantly single doses of cyclosporine (200 mg) and reduced dose aliskiren (75 mg), the mean Cmax of aliskiren was increased by approximately 2.5-fold (90% CI: 1.96 to 3.17) and the mean AUC by approximately 4.3 fold (90% CI: 3.52 to 5.21), compared to when these subjects received aliskiren alone.
The concomitant administration of aliskiren with cyclosporine prolonged the median aliskiren elimination half-life (26 hours versus 43 to 45 hours) and the Tmax (0.5 hours versus 1.5 to 2.0 hours).
The mean AUC and Cmax of cyclosporine were comparable to reported literature values.
Coadministration of cyclosporine and aliskiren in these subjects also resulted in an increase in the number and/or intensity of adverse events, mainly headache, hot flush, nausea, vomiting, and somnolence.
The coadministration of cyclosporine with aliskiren is not recommended.
Bosentan In healthy subjects, coadministration of bosentan and cyclosporine resulted in time-dependent mean increases in dose-normalized bosentan trough concentrations (i.e., approximately 21-fold on day 1 and 2-fold on day 8 (steady state)) compared to when bosentan was given alone as a single dose on day 1.
(See also Effect of Drugs and Other Agents on Cyclosporine Pharmacokinetics and/or Safety) Coadministration of cyclosporine with bosentan should be avoided.
Dabigatran The effect of cyclosporine on dabigatran concentrations had not been formally studied.
Concomitant administration of dabigatran and cyclosporine may result in increased plasma dabigatran concentrations due to the P-gp inhibitory activity of cyclosporine.
Coadministration of cyclosporine with dabigatran should be avoided.
Potassium Sparing Diuretics Cyclosporine should not be used with potassium-sparing diuretics because hyperkalemia can occur.
Caution is also required when cyclosporine is coadministered with potassium-sparing drugs (e.g., angiotensin-converting enzyme inhibitors, angiotensin II receptor antagonists), potassium-containing drugs as well as in patients on a potassium-rich diet.
Control of potassium levels in these situations is advisable.
Nonsteroidal Anti-inflammatory Drug (NSAID) Interactions Clinical status and serum creatinine should be closely monitored when cyclosporine is used with NSAIDs in rheumatoid arthritis patients.
(See WARNINGS) Pharmacodynamic interactions have been reported to occur between cyclosporine and both naproxen and sulindac, in that concomitant use is associated with additive decreases in renal function, as determined by 99mTc-diethylenetriaminepentaacetic acid (DTPA) and (p-aminohippuric acid) PAH clearances.
Although concomitant administration of diclofenac does not affect blood concentrations of cyclosporine, it has been associated with approximate doubling of diclofenac blood levels and occasional reports of reversible decreases in renal function.
Consequently, the dose of diclofenac should be in the lower end of the therapeutic range.
Methotrexate Interaction Preliminary data indicate that when methotrexate and cyclosporine were coadministered to rheumatoid arthritis patients (N=20), methotrexate concentrations (AUCs) were increased approximately 30% and the concentrations (AUCs) of its metabolite, 7-hydroxy methotrexate, were decreased by approximately 80%.
The clinical significance of this interaction is not known.
Cyclosporine concentrations do not appear to have been altered (N=6).
Sirolimus Elevations in serum creatinine were observed in studies using sirolimus in combination with full-dose cyclosporine.
This effect is often reversible with cyclosporine dose reduction.
Simultaneous coadministration of cyclosporine significantly increases blood levels of sirolimus.
To minimize increases in sirolimus blood concentrations, it is recommended that sirolimus be given 4 hours after cyclosporine administration.
Nifedipine Frequent gingival hyperplasia when nifedipine is given concurrently with cyclosporine has been reported.
The concomitant use of nifedipine should be avoided in patients in whom gingival hyperplasia develops as a side effect of cyclosporine.
Methylprednisolone Convulsions when high dose methylprednisolone is given concomitantly with cyclosporine have been reported.
Other Immunosuppressive Drugs and Agents Psoriasis patients receiving other immunosuppressive agents or radiation therapy (including PUVA and UVB) should not receive concurrent cyclosporine because of the possibility of excessive immunosuppression.
Effect Of Cyclosporine On The Efficacy Of Live Vaccines During treatment with cyclosporine, vaccination may be less effective.
The use of live vaccines should be avoided.

Side Effects & Drug Interactions SIDE EFFECTS The following serious adverse reactions are described elsewhere in the labeling: Potential for Eye Injury and Contamination [see WARNINGS AND PRECAUTIONS] Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In clinical trials, the most common adverse reaction following the use of RESTASIS®was ocular burning (17%).
Other reactions reported in 1% to 5% of patients included conjunctival hyperemia, discharge, epiphora, eye pain, foreign body sensation, pruritus, stinging, and visual disturbance (most often blurring).
Post-marketing Experience The following adverse reactions have been identified during post approval use of RESTASIS®.
Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Reported reactions have included: hypersensitivity (including eye swelling, urticaria, rare cases of severe angioedema, face swelling, tongue swelling, pharyngeal edema, and dyspnea); and superficial injury of the eye (from the vial tip touching the eye during administration).
DRUG INTERACTIONS No information provided.
Side Effects & Drug Interactions SIDE EFFECTS Kidney, Liver, and Heart Transplantation The principal adverse reactions of cyclosporine therapy are renal dysfunction, tremor, hirsutism, hypertension, and gum hyperplasia.
Hypertension Hypertension, which is usually mild to moderate, may occur in approximately 50% of patients following renal transplantation and in most cardiac transplant patients.
Glomerular Capillary Thrombosis Glomerular capillary thrombosis has been found in patients treated with cyclosporine and may progress to graft failure.
The pathologic changes resembled those seen in the hemolytic-uremic syndrome and included thrombosis of the renal microvasculature, with platelet-fibrin thrombi occluding glomerular capillaries and afferent arterioles, microangiopathic hemolytic anemia, thrombocytopenia, and decreased renal function.
Similar findings have been observed when other immunosuppressives have been employed post-transplantation.
Hypomagnesemia Hypomagnesemia has been reported in some, but not all, patients exhibiting convulsions while on cyclosporine therapy.
Although magnesium-depletion studies in normal subjects suggest that hypomagnesemia is associated with neurologic disorders, multiple factors, including hypertension, high dose methylprednisolone, hypocholesterolemia, and nephrotoxicity associated with high plasma concentrations of cyclosporine appear to be related to the neurological manifestations of cyclosporine toxicity.Clinical Studies In controlled studies, the nature, severity, and incidence of the adverse events that were observed in 493 transplanted patients treated with Neoral® were comparable with those observed in 208 transplanted patients who received Sandimmune® in these same studies when the dosage of the two drugs was adjusted to achieve the same cyclosporine blood trough concentrations.
Based on the historical experience with Sandimmune®, the following reactions occurred in 3% or greater of 892 patients involved in clinical trials of kidney, heart, and liver transplants.

The following reactions occurred in 2% or less of cyclosporine-treated patients: allergic reactions, anemia, anorexia, confusion, conjunctivitis, edema, fever, brittle fingernails, gastritis, hearing loss, hiccups, hyperglycemia, migraine (Neoral®) muscle pain, peptic ulcer, thrombocytopenia, tinnitus.
The following reactions occurred rarely: anxiety, chest pain, constipation, depression, hair breaking, hematuria, joint pain, lethargy, mouth sores, myocardial infarction, night sweats, pancreatitis, pruritus, swallowing difficulty, tingling, upper GI bleeding, visual disturbance, weakness, weight loss.
Patients receiving immunosuppressive therapies, including cyclosporine and cyclosporine -containing regimens, are at increased risk of infections (viral, bacterial, fungal, parasitic).
Both generalized and localized infections can occur.
Pre-existing infections may also be aggravated.
Fatal outcomes have been reported.

In some cases, patients have been unable to continue cyclosporine, however, the final decision on treatment discontinuation should be made by the treating physician following the careful assessment of benefits versus risks.
The principal adverse reactions associated with the use of cyclosporine in rheumatoid arthritis are renal dysfunction (see WARNINGS), hypertension (see PRECAUTIONS), headache, gastrointestinal disturbances, and hirsutism/hypertrichosis.
In rheumatoid arthritis patients treated in clinical trials within the recommended dose range, cyclosporine therapy was discontinued in 5.3% of the patients because of hypertension and in 7% of the patients because of increased creatinine.
These changes are usually reversible with timely dose decrease or drug discontinuation.
The frequency and severity of serum creatinine elevations increase with dose and duration of cyclosporine therapy.
These elevations are likely to become more pronounced without dose reduction or discontinuation.

Psoriasis The principal adverse reactions associated with the use of cyclosporine in patients with psoriasis are renal dysfunction, headache, hypertension, hypertriglyceridemia, hirsutism/hypertrichosis, paresthesia or hyperesthesia, influenza-like symptoms, nausea/vomiting, diarrhea, abdominal discomfort, lethargy, and musculoskeletal or joint pain.
In psoriasis patients treated in US controlled clinical studies within the recommended dose range, cyclosporine therapy was discontinued in 1.0% of the patients because of hypertension and in 5.4% of the patients because of increased creatinine.
In the majority of cases, these changes were reversible after dose reduction or discontinuation of cyclosporine.
There has been one reported death associated with the use of cyclosporine in psoriasis.
A 27-year-old male developed renal deterioration and was continued on cyclosporine.
He had progressive renal failure leading to death.
Frequency and severity of serum creatinine increases with dose and duration of cyclosporine therapy.
These elevations are likely to become more pronounced and may result in irreversible renal damage without dose reduction or discontinuation.

Mild hypomagnesemia and hyperkalemia may occur but are asymptomatic.
Increases in uric acid may occur and attacks of gout have been rarely reported.
A minor and dose related hyperbilirubinemia has been observed in the absence of hepatocellular damage.
Cyclosporine therapy may be associated with a modest increase of serum triglycerides or cholesterol.
Elevations of triglycerides ( > 750 mg/dL) occur in about 15% of psoriasis patients; elevations of cholesterol ( > 300 mg/dL) are observed in less than 3% of psoriasis patients.
Generally these laboratory abnormalities are reversible upon dose reduction or discontinuation of cyclosporine.
DRUG INTERACTIONS Effect of Drugs and Other Agents on Cyclosporine Pharmacokinetics and/or Safety All of the individual drugs cited below are well substantiated to interact with cyclosporine.
In addition, concomitant non-steroidal anti-inflammatory drugs, particularly in the setting of dehydration, may potentiate renal dysfunction.
Drugs That May Potentiate Renal Dysfunction Antibiotics Antineoplastics Antifungals Anti-inflammatory Drugs Gastrointestinal Agents Immunosuppressives Other Drugs ciprofloxacin gentamicin tobramycin vancomycin trimethoprim with sulfamethoxazole melphalan amphotericin B ketoconazole azapropazon colchicine diclofenac naproxen sulindac cimetidine ranitidine tacrolimus fibric acid derivatives (e.g., bezafibrate, fenofibrate) methotrexate Cyclosporine is extensively metabolized by CYP 3A isoenzymes, in particular CYP3A4, and is a substrate of the multidrug efflux transporter P-glycoprotein.
Various agents are known to either increase or decrease plasma or whole blood of cyclosporine levels usually by inhibition or induction of CYP3A4 or P-glycoprotein transporter or both.
Compounds that decrease cyclosporine absorption such as orlistat should be avoided.
Monitoring of circulating cyclosporine concentrations and appropriate Neoral® dosage adjustment are essential when these drugs are used concomitantly.
(See Blood Concentration Monitoring) Drugs That Increase Cyclosporine Concentrations Calcium Channel Blockers Antifungals Antibiotics Glucocorticoids Other Drugs diltiazem nicardipine verapamil fluconazole itraconazole ketoconazole voriconazole azithromycin clarithromycin erythromycin quinupristin/ dalfopristin methylprednisolone Allopurinol Amiodarone Bromocriptine colchicine danazol imatinib metoclopramide nefazodone oral contraceptives HIV Protease inhibitors The HIV protease inhibitors (e.g., indinavir, nelfinavir, ritonavir, and saquinavir) are known to inhibit cytochrome P-450 3A and thus could potentially increase the concentrations of cyclosporine, however no formal studies of the interaction are available.
Care should be exercised when these drugs are administered concomitantly.
Grapefruit juice Grapefruit and grapefruit juice affect metabolism, increasing blood concentrations of cyclosporine, thus should be avoided.
Drugs/Dietary Supplements That Decrease Cyclosporine Concentrations Antibiotics Anticonvulsants Other Drugs/Dietary Supplements nafcillin rifampin phenytoin carbamazepine oxcarbazepine phenobarbital sulfinpyrazone terbinafine ticlopidine bosentan octreotide orlistat St.
John's Wort St.
John's Wort There have been reports of a serious drug interaction between cyclosporine and the herbal dietary supplement, St.
John's Wort.
This interaction has been reported to produce a marked reduction in the blood concentrations of cyclosporine, resulting in subtherapeutic levels, rejection of transplanted organs, and graft loss.
Rifabutin Rifabutin is known to increase the metabolism of other drugs metabolized by the cytochrome P-450 system.
The interaction between rifabutin and cyclosporine has not been studied.
Care should be exercised when these two drugs are administered concomitantly.
Effect of Cyclosporine on the Pharmacokinetics and/or Safety of Other Drugs or Agents Cyclosporine is an inhibitor of CYP3A4 and of the multidrug efflux transporter P-glycoprotein and may increase plasma concentrations of comedications that are substrates of CYP3A4 or Pglycoprotein or both.
Cyclosporine may reduce the clearance of digoxin, colchicine, prednisolone, HMG-CoA reductase inhibitors (statins), and, aliskiren, repaglinide, NSAIDs, sirolimus, etoposide, and other drugs.
See the full prescribing information of the other drug for further information and specific recommendations.
The decision on co-administration of cyclosporine with other drugs or agents should be made by the physician following the careful assessment of benefits and risks.
Digoxin Severe digitalis toxicity has been seen within days of starting cyclosporine in several patients taking digoxin.
If digoxin is used concurrently with cyclosporine, serum digoxin concentrations should be monitored.
Colchicine There are reports on the potential of cyclosporine to enhance the toxic effects of colchicine such as myopathy and neuropathy, especially in patients with renal dysfunction.
Concomitant administration of cyclosporine and colchicine results in significant increases in colchicine plasma concentrations.
If colchicine is used concurrently with cyclosporine, a reduction in the dosage of colchicine is recommended.
HMG-CoA reductase inhibitors (statins) Literature and postmarketing cases of myotoxicity, including muscle pain and weakness, myositis, and rhabdomyolysis, have been reported with concomitant administration of cyclosporine with lovastatin, simvastatin, atorvastatin, pravastatin, and, rarely fluvastatin.
When concurrently administered with cyclosporine, the dosage of these statins should be reduced according to label recommendations.
Statin therapy needs to be temporarily withheld or discontinued in patients with signs and symptoms of myopathy or those with risk factors predisposing to severe renal injury, including renal failure, secondary to rhabdomyolysis.
Repaglinide Cyclosporine may increase the plasma concentrations of repaglinide and thereby increase the risk of hypoglycemia.
In 12 healthy male subjects who received two doses of 100mg cyclosporine capsule orally 12 hours apart with a single dose of 0.25mg repaglinide tablet (one half of a 0.5mg tablet) orally 13 hours after the cyclosporine initial dose, the repaglinide mean Cmax and AUC were increased 1.8 fold (range: 0.6 - 3.7 fold) and 2.4 fold (range 1.2 - 5.3 fold), respectively.
Close monitoring of blood glucose level is advisable for a patient taking cyclosporine and repaglinide concomitantly.
Aliskiren Cyclosporine alters the pharmacokinetics of aliskiren, a substrate of P-glycoprotein and CYP3A4.
In 14 healthy subjects who received concomitantly single doses of cyclosporine (200 mg) and reduced dose aliskiren (75 mg), the mean Cmax of aliskiren was increased by approximately 2.5 fold (90% CI: 1.96 - 3.17) and the mean AUC by approximately 4.3 fold (90% CI: 3.52 - 5.21), compared to when these subjects received aliskiren alone.
The concomitant administration of aliskiren with cyclosporine prolonged the median aliskiren elimination half-life (26 hours versus 43 to 45 hours) and the Tmax (0.5 hours versus 1.5 to 2.0 hours).
The mean AUC and Cmax of cyclosporine were comparable to reported literature values.
Co-administration of cyclosporine and aliskiren in these subjects also resulted in an increase in the number and/or intensity of adverse events, mainly headache, hot flush, nausea, vomiting, and somnolence.
The co-administration of cyclosporine with aliskiren is not recommended.
Potassium-Sparing Diuretics Cyclosporine should not be used with potassium-sparing diuretics because hyperkalemia can occur.
Caution is also required when cyclosporine is co-administered with potassium sparing drugs (e.g.
angiotensin converting enzyme inhibitors, angiotensin II receptor antagonists), potassium containing drugs as well as in patients on a potassium rich diet.
Control of potassium levels in these situations is advisable.
Nonsteroidal Anti-inflammatory Drug (NSAID) Interactions Clinical status and serum creatinine should be closely monitored when cyclosporine is used with nonsteroidal anti-inflammatory agents in rheumatoid arthritis patients.
(See WARNINGS) Pharmacodynamic interactions have been reported to occur between cyclosporine and both naproxen and sulindac, in that concomitant use is associated with additive decreases in renal function, as determined by 99mTc-diethylenetriaminepentaacetic acid (DTPA) and (p-aminohippuric acid) PAH clearances.
Although concomitant administration of diclofenac does not affect blood concentrations of cyclosporine, it has been associated with approximate doubling of diclofenac blood concentrations and occasional reports of reversible decreases in renal function.
Consequently, the dose of diclofenac should be in the lower end of the therapeutic range.
Methotrexate Interaction Preliminary data indicate that when methotrexate and cyclosporine were co-administered to rheumatoid arthritis patients (N=20), methotrexate concentrations (AUCs) were increased approximately 30% and the concentrations (AUCs) of its metabolite, 7-hydroxy methotrexate, were decreased by approximately 80%.
The clinical significance of this interaction is not known.
Cyclosporine concentrations do not appear to have been altered (N=6).
Sirolimus Elevations in serum creatinine were observed in studies using sirolimus in combination with full-dose cyclosporine.
This effect is often reversible with cyclosporine dose reduction.
Simultaneous coadministration of cyclosporine significantly increases blood concentrations of sirolimus.
To minimize increases in sirolimus concentrations, it is recommended that sirolimus be given 4 hours after cyclosporine administration.
Nifedipine Frequent gingival hyperplasia when nifedipine is given concurrently with cyclosporine have been reported.
Methylprednisolone Convulsions when high dose methylprednisolone is given concurrently with cyclosporine have been reported.
Other Immunosuppressive Drugs and Agents Psoriasis patients receiving other immunosuppressive agents or radiation therapy (including PUVA and UVB) should not receive concurrent cyclosporine because of the possibility of excessive immunosuppression.
Effect of Cyclosporine on the Efficacy of Live Vaccines During treatment with cyclosporine, vaccination may be less effective.
The use of live vaccines should be avoided.

Warnings & Precautions WARNINGS Kidney, Liver, And Heart Transplant (See BOXED WARNING): Sandimmune (cyclosporine), when used in high doses, can cause hepatotoxicity and nephrotoxicity.
Nephrotoxicity It is not unusual for serum creatinine and BUN levels to be elevated during Sandimmune (cyclosporine) therapy.
These elevations in renal transplant patients do not necessarily indicate rejection, and each patient must be fully evaluated before dosage adjustment is initiated.
Nephrotoxicity has been noted in 25% of cases of renal transplantation, 38% of cases of cardiac transplantation, and 37% of cases of liver transplantation.
Mild nephrotoxicity was generally noted 2 to 3 months after transplant and consisted of an arrest in the fall of the preoperative elevations of BUN and creatinine at a range of 35 to 45 mg/dl and 2.0 to 2.5 mg/dl, respectively.
These elevations were often responsive to dosage reduction.
More overt nephrotoxicity was seen early after transplantation and was characterized by a rapidly rising BUN and creatinine.
Since these events are similar to rejection episodes, care must be taken to differentiate between them.
This form of nephrotoxicity is usually responsive to Sandimmune (cyclosporine) dosage reduction.
Although specific diagnostic criteria which reliably differentiate renal graft rejection from drug toxicity have not been found, a number of parameters have been significantly associated to one or the other.
It should be noted however, that up to 20% of patients may have simultaneous nephrotoxicity and rejection.

From 5% to 15% of transplant recipients will fail to show a reduction in a rising serum creatinine despite a decrease or discontinuation of cyclosporine therapy.
Renal biopsies from these patients will demonstrate an interstitial fibrosis with tubular atrophy.
In addition, toxic tubulopathy, peritubular capillary congestion, arteriolopathy, and a striped form of interstitial fibrosis with tubular atrophy may be present.
Though none of these morphologic changes is entirely specific, a histologic diagnosis of chronic progressive cyclosporine-associated nephrotoxicity requires evidence of these.
When considering the development of chronic nephrotoxicity it is noteworthy that several authors have reported an association between the appearance of interstitial fibrosis and higher cumulative doses or persistently high circulating trough concentrations of cyclosporine.
This is particularly true during the first 6 posttransplant months when the dosage tends to be highest and when, in kidney recipients, the organ appears to be most vulnerable to the toxic effects of cyclosporine.
Among other contributing factors to the development of interstitial fibrosis in these patients must be included, prolonged perfusion time, warm ischemia time, as well as episodes of acute toxicity, and acute and chronic rejection.
The reversibility of interstitial fibrosis and its correlation to renal function have not yet been determined.
Impaired renal function at any time requires close monitoring, and frequent dosage adjustment may be indicated.
In patients with persistent high elevations of BUN and creatinine who are unresponsive to dosage adjustments, consideration should be given to switching to other immunosuppressive therapy.
In the event of severe and unremitting rejection, it is preferable to allow the kidney transplant to be rejected and removed rather than increase the Sandimmune (cyclosporine) dosage to a very high level in an attempt to reverse the rejection.
Due to the potential for additive or synergistic impairment of renal function, caution should be exercised when coadministering Sandimmune with other drugs that may impair renal function.
(See PRECAUTIONS: DRUG INTERACTIONS) Thrombotic Microangiopathy Occasionally patients have developed a syndrome of thrombocytopenia and microangiopathic hemolytic anemia which may result in graft failure.
The vasculopathy can occur in the absence of rejection and is accompanied by avid platelet consumption within the graft as demonstrated by Indium 111 labeled platelet studies.
Neither the pathogenesis nor the management of this syndrome is clear.
Though resolution has occurred after reduction or discontinuation of Sandimmune (cyclosporine) and 1) administration of streptokinase and heparin or 2) plasmapheresis, this appears to depend upon early detection with Indium 111 labeled platelet scans.
(See ADVERSE REACTIONS) Hyperkalemia Significant hyperkalemia (sometimes associated with hyperchloremic metabolic acidosis) and hyperuricemia have been seen occasionally in individual patients.
Hepatotoxicity Cases of hepatotoxicity and liver injury including cholestasis, jaundice, hepatitis, and liver failure have been reported in patients treated with cyclosporine.
Most reports included patients with significant comorbidities, underlying conditions and other confounding factors including infectious complications and comedications with hepatotoxic potential.
In some cases, mainly in transplant patients, fatal outcomes have been reported (See ADVERSE REACTIONS, Postmarketing Experience) Hepatotoxicity, usually manifested by elevations in hepatic enzymes and bilirubin, was reported in patients treated with cyclosporine in clinical trials: 4% in renal transplantation, 7% in cardiac transplantation, and 4% in liver transplantation.
This was usually noted during the first month of therapy when high doses of Sandimmune (cyclosporine) were used.
The chemistry elevations usually decreased with a reduction in dosage.
Malignancies As in patients receiving other immunosuppressants, those patients receiving Sandimmune (cyclosporine) are at increased risk for development of lymphomas and other malignancies, particularly those of the skin.
The increased risk appears related to the intensity and duration of immunosuppression rather than to the use of specific agents.
Because of the danger of oversuppression of the immune system, which can also increase susceptibility to infection, Sandimmune (cyclosporine) should not be administered with other immunosuppressive agents except adrenal corticosteroids.
The efficacy and safety of cyclosporine in combination with other immunosuppressive agents have not been determined.
Some malignancies may be fatal.
Transplant patients receiving cyclosporine are at increased risk for serious infection with fatal outcome.
Serious Infections Patients receiving immunosuppressants, including Sandimmune, are at increased risk of developing bacterial, viral, fungal, and protozoal infections, including opportunistic infections.
These infections may lead to serious, including fatal, outcomes (See BOXED WARNING, and ADVERSE REACTIONS).
Polyoma Virus Infections Patients receiving immunosuppressants, including Sandimmune, are at increased risk for opportunistic infections, including polyoma virus infections.
Polyoma virus infections in transplant patients may have serious, and sometimes, fatal outcomes.
These include cases of JC virus-associated progressive multifocal leukoencephalopathy (PML), and polyoma virus-associated nephropathy (PVAN), especially due to BK virus infection, which have been observed in patients receiving cyclosporine.
PVAN is associated with serious outcomes, including deteriorating renal function and renal graft loss, (See ADVERSE REACTIONS/Postmarketing Experience).
Patient monitoring may help detect patients at risk for PVAN.
Cases of PML have been reported in patients treated with cyclosporine_ PML, which is sometimes fatal, commonly presents with hemiparesis, apathy, confusion, cognitive deficiencies and ataxia.
Risk factors for PML include treatment with immunosuppressant therapies and impairment of immune function.
In immunosuppressed patients, physicians should consider PML in the differential diagnosis in patients reporting neurological symptoms and consultation with a neurologist should be considered as clinically indicated.
Consideration should be given to reducing the total immunosuppression in transplant patients who develop PML or PVAN.
However, reduced immunosuppression may place the graft at risk.
Neurotoxicity There have been reports of convulsions in adult and pediatric patients receiving cyclosporine, particularly in combination with high-dose methylprednisolone.
Encephalopathy, including Posterior Reversible Encephalopathy Syndrome (PRES), has been described both in postmarketing reports and in the literature.
Manifestations include impaired consciousness, convulsions, visual disturbances (including blindness), loss of motor function, movement disorders and psychiatric disturbances.
In many cases, changes in the white matter have been detected using imaging techniques and pathologic specimens.
Predisposing factors such as hypertension, hypomagnesemia, hypocholesterolemia, high-dose corticosteroids, high cyclosporine blood concentrations, and graft-versus-host disease have been noted in many but not all of the reported cases.
The changes in most cases have been reversible upon discontinuation of cyclosporine, and in some cases, improvement was noted after reduction of dose.
It appears that patients receiving liver transplant are more susceptible to encephalopathy than those receiving kidney transplant.
Another rare manifestation of cyclosporine-induced neurotoxicity is optic disc edema including papilloedema, with possible visual impairment, secondary to benign intracranial hypertension.
Specific Excipients Anaphylactic Reactions Rarely (approximately 1 in 1000), patients receiving Sandimmune Injection (cyclosporine injection, USP) have experienced anaphylactic reactions.
Although the exact cause of these reactions is unknown, it is believed to be due to the Cremophor EL (polyoxyethylated castor oil) used as the vehicle for the intravenous (IV) formulation.
These reactions can consist of flushing of the face and upper thorax, and noncardiogenic pulmonary edema, with acute respiratory distress, dyspnea, wheezing, blood pressure changes, and tachycardia.
One patient died after respiratory arrest and aspiration pneumonia.
In some cases, the reaction subsided after the infusion was stopped.
Patients receiving Sandimmune Injection (cyclosporine injection, USP) should be under continuous observation for at least the first 30 minutes following the start of the infusion and at frequent intervals thereafter.
If anaphylaxis occurs, the infusion should be stopped.
An aqueous solution of epinephrine 1:1000 should be available at the bedside as well as a source of oxygen.
Anaphylactic reactions have not been reported with the soft gelatin capsules or oral solution which lack Cremophor EL (polyoxyethylated castor oil).
In fact, patients experiencing anaphylactic reactions have been treated subsequently with the soft gelatin capsules or oral solution without incident.
Alcohol (ethanol) The alcohol content (See DESCRIPTION) of Sandimmune should be taken into account when given to patients in whom alcohol intake should be avoided or minimized, e.g.
pregnant or breastfeeding women, in patients presenting with liver disease or epilepsy, in alcoholic patients, or pediatric patients.
For an adult weighing 70 kg, the maximum daily oral dose would deliver about 1 gram of alcohol which is approximately 6% of the amount of alcohol contained in a standard drink.
The daily intravenous dose would deliver approximately 15% of the amount of alcohol contained in a standard drink.
Care should be taken in using Sandimmune (cyclosporine) with nephrotoxic drugs.
(See PRECAUTIONS) Conversion from Neoral to Sandimmune Because Sandimmune (cyclosporine) is not bioequivalent to Neoral, conversion from Neoral to Sandimmune (cyclosporine) using a 1:1 ratio (mg/kg/day) may result in a lower cyclosporine blood concentration.
Conversion from Neoral to Sandimmune (cyclosporine) should be made with increased blood concentration monitoring to avoid the potential of underdosing.
PRECAUTIONS General Patients with malabsorption may have difficulty in achieving therapeutic concentrations with Sandimmune Soft Gelatin Capsules or Oral Solution.
Hypertension Hypertension is a common side effect of Sandimmune (cyclosporine) therapy.
(See ADVERSE REACTIONS) Mild or moderate hypertension is more frequently encountered than severe hypertension and the incidence decreases over time.
Antihypertensive therapy may be required.
Control of blood pressure can be accomplished with any of the common antihypertensive agents.
However, since cyclosporine may cause hyperkalemia, potassium-sparing diuretics should not be used.
While calcium antagonists can be effective agents in treating cyclosporine-associated hypertension, care should be taken since interference with cyclosporine metabolism may require a dosage adjustment.
(See DRUG INTERACTIONS) Vaccination During treatment with Sandimmune (cyclosporine), vaccination may be less effective and the use of live attenuated vaccines should be avoided.
Laboratory Tests Renal and liver functions should be assessed repeatedly by measurement of BUN, serum creatinine, serum bilirubin, and liver enzymes.
Carcinogenesis, Mutagenesis, And Impairment Of Fertility Cyclosporine gave no evidence of mutagenic or teratogenic effects in appropriate test systems.
Only at dose levels toxic to dams, were adverse effects seen in reproduction studies in rats.
(See Pregnancy) Carcinogenicity studies were carried out in male and female rats and mice.
In the 78-week mouse study, at doses of 1, 4, and 16 mg/kg/day, evidence of a statistically significant trend was found for lymphocytic lymphomas in females, and the incidence of hepatocellular carcinomas in mid-dose males significantly exceeded the control value.
In the 24–month rat study, conducted at 0.5, 2, and 8 mg/kg/day, pancreatic islet cell adenomas significantly exceeded the control rate in the low-dose level.
The hepatocellular carcinomas and pancreatic islet cell adenomas were not dose related.
No impairment in fertility was demonstrated in studies in male and female rats.
Cyclosporine has not been found mutagenic/genotoxic in the Ames Test, the V79-HGPRT Test, the micronucleus test in mice and Chinese hamsters, the chromosome-aberration tests in Chinese hamster bone marrow, the mouse dominant lethal assay, and the DNA-repair test in sperm from treated mice.
A recent study analyzing sister chromatid exchange (SCE) induction by cyclosporine using human lymphocytes in vitro gave indication of a positive effect (i.e., induction of SCE), at high concentrations in this system.
In two published research studies, rabbits exposed to cyclosporine in utero (10 mg/kg/day subcutaneously) demonstrated reduced numbers of nephrons, renal hypertrophy, systemic hypertension and progressive renal insufficiency up to 35 weeks of age.
Pregnant rats which received 12 mg/kg/day of cyclosporine intravenously (twice the recommended human intravenous dose) had fetuses with an increased incidence of ventricular septal defect.
These findings have not been demonstrated in other species and their relevance for humans is unknown.
An increased incidence of malignancy is a recognized complication of immunosuppression in recipients of organ transplants.
The most common forms of neoplasms are non-Hodgkin's lymphoma and carcinomas of the skin.
The risk of malignancies in cyclosporine recipients is higher than in the normal, healthy population, but similar to that in patients receiving other immunosuppressive therapies.
It has been reported that reduction or discontinuance of immunosuppression may cause the lesions to regress.
Pregnancy Pregnancy Category C Animal studies have shown reproductive toxicity in rats and rabbits.
Cyclosporine gave no evidence of mutagenic or teratogenic effects in the standard test systems with oral application (rats up to 17 mg/kg and rabbits up to 30 mg/kg per day orally).
Sandimmune Oral Solution (cyclosporine oral solution, USP) has been shown to be embryo-and fetotoxic in rats and rabbits when given in doses 2-5 times the human dose.
At toxic doses (rats at 30 mg/kg/day and rabbits at 100 mg/kg/day), Sandimmune Oral Solution (cyclosporine oral solution, USP) was embryo-and fetotoxic as indicated by increased pre-and postnatal mortality and reduced fetal weight together with related skeletal retardations.
In the well-tolerated dose range (rats at up to 17 mg/kg/day and rabbits at up to 30 mg/kg/day), Sandimmune Oral Solution (cyclosporine oral solution, USP) proved to be without any embryolethal or teratogenic effects.
There are no adequate and well-controlled studies in pregnant women and therefore, Sandimmune (cyclosporine) should not be used during pregnancy unless the potential benefit to the mother justifies the potential risk to the fetus.
In pregnant transplant recipients who are being treated with immunosuppressants, the risk of premature birth is increased.
The following data represent the reported outcomes of 116 pregnancies in women receiving Sandimmune (cyclosporine) during pregnancy, 90% of whom were transplant patients, and most of whom received Sandimmune (cyclosporine) throughout the entire gestational period.
Since most of the patients were not prospectively identified, the results are likely to be biased toward negative outcomes.
The only consistent patterns of abnormality were premature birth (gestational period of 28 to 36 weeks) and low birth weight for gestational age.
It is not possible to separate the effects of Sandimmune (cyclosporine) on these pregnancies from the effects of the other immunosuppressants, the underlying maternal disorders, or other aspects of the transplantation milieu.
Sixteen fetal losses occurred.
Most of the pregnancies (85 of 100) were complicated by disorders; including, preeclampsia, eclampsia, premature labor, abruptio placentae, oligohydramnios, Rh incompatibility and fetoplacental dysfunction.
Preterm delivery occurred in 47%.
Seven malformations were reported in 5 viable infants and in 2 cases of fetal loss.
Twenty-eight percent of the infants were small for gestational age.
Neonatal complications occurred in 27%.
In a report of 23 children followed up to 4 years, postnatal development was said to be normal.
More information on cyclosporine use in pregnancy is available from Novartis Pharmaceuticals Corporation.
A limited number of observations in children exposed to cyclosporine in utero are available, up to an age of approximately 7 years.
Renal function and blood pressure in these children were normal.
The alcohol content of the Sandimmune formulations should also be taken into account in pregnant women.
(See WARNINGS, Special Excipients) Nursing Mothers Cyclosporine is present in breast milk.
Because of the potential for serious adverse drug reactions in nursing infants from Sandimmune, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Sandimmune contains ethanol.
Ethanol will be present in human milk at levels similar to that found in maternal serum and if present in breast milk will be orally absorbed by a nursing infant.
(See WARNINGS) Pediatric Use Although no adequate and well-controlled studies have been conducted in children, patients as young as 6 months of age have received the drug with no unusual adverse effects.
Geriatric Use Clinical studies of Sandimmune (cyclosporine) did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger patients.
Other reported clinical experience has not identified differences in responses between the elderly and younger patients.
In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
Warnings & Precautions WARNINGS Included as part of the PRECAUTIONS section.
PRECAUTIONS Potential For Eye Injury And Contamination Be careful not to touch the vial tip to your eye or other surfaces to avoid potential for eye injury and contamination.
Use With Contact Lenses RESTASIS® should not be administered while wearing contact lenses.
Patients with decreased tear production typically should not wear contact lenses.
If contact lenses are worn, they should be removed prior to the administration of the emulsion.
Lenses may be reinserted 15 minutes following administration of RESTASIS® ophthalmic emulsion.
Nonclinical Toxicology Carcinogenesis, Mutagenesis, Impairment Of Fertility Carcinogenesis Systemic carcinogenicity studies were conducted in male and female mice and rats.
In the 78-week oral (diet) mouse study, at doses of 1, 4, and 16 mg/kg/day, evidence of a statistically significant trend was found for lymphocytic lymphomas in females, and the incidence of hepatocellular carcinomas in mid-dose males significantly exceeded the control value.
In the 24-month oral (diet) rat study, conducted at 0.5, 2, and 8 mg/kg/day, pancreatic islet cell adenomas significantly exceeded the control rate in the low dose level.
The hepatocellular carcinomas and pancreatic islet cell adenomas were not dose related.
The low doses in mice and rats are approximately 80 times greater (normalized to body surface area) than the daily recommended human dose of one drop (approximately 28 mcL) of 0.05% RESTASIS® twice daily into each eye of a 60 kg person (0.001 mg/kg/day), assuming that the entire dose is absorbed.
Mutagenesis Cyclosporine has not been found to be mutagenic/genotoxic in the Ames Test, the V79-HGPRT Test, the micronucleus test in mice and Chinese hamsters, the chromosome-aberration tests in Chinese hamster bone-marrow, the mouse dominant lethal assay, and the DNA-repair test in sperm from treated mice.
A study analyzing sister chromatid exchange (SCE) induction by cyclosporine using human lymphocytes in vitro gave indication of a positive effect (i.e., induction of SCE).
Impairment Of Fertility No impairment in fertility was demonstrated in studies in male and female rats receiving oral doses of cyclosporine up to 15 mg/kg/day (approximately 2,000 times the human daily dose of 0.001 mg/kg/day normalized to body surface area) for 9 weeks (male) and 2 weeks (female) prior to mating.
Use In Specific Populations Pregnancy Risk Summary Clinical administration of cyclosporine ophthalmic emulsion 0.05% is not detected systemically following topical ocular administration [see CLINICAL PHARMACOLOGY], and maternal use is not expected to result in fetal exposure to the drug.
Oral administration of cyclosporine to pregnant rats or rabbits did not produce teratogenicity at clinically relevant doses [see Data].
Data Animal Data At maternally toxic doses (30 mg/kg/day in rats and 100 mg/kg/day in rabbits), cyclosporine oral solution (USP) was teratogenic as indicated by increased pre- and postnatal mortality, reduced fetal weight and skeletal retardations.
These doses (normalized to body surface area) are 5,000 and 32,000 times greater, respectively, than the daily recommended human dose of one drop (approximately 28 mcL) of cyclosporine ophthalmic emulsion 0.05% twice daily into each eye of a 60 kg person (0.001 mg/kg/day), assuming that the entire dose is absorbed.
No evidence of embryofetal toxicity was observed in rats or rabbits receiving cyclosporine during organogenesis at oral doses up to 17 mg/kg/day or 30 mg/kg/day, respectively.
These doses in rats and rabbits are approximately 3,000 and 10,000 times greater, respectively, than the daily recommended human dose.
An oral dose of 45 mg/kg/day cyclosporine administered to rats from Day 15 of pregnancy until Day 21 postpartum produced maternal toxicity and an increase in postnatal mortality in offspring.
This dose is 7,000 times greater than the daily recommended human dose.
No adverse effects in dams or offspring were observed at oral doses up to 15 mg/kg/day (2,000 times greater than the daily recommended human dose).
Lactation Risk Summary Cyclosporine is known to appear in human milk following systemic administration, but its presence in human milk following topical treatment has not been investigated.
Although blood concentrations are undetectable following topical administration of RESTASIS® ophthalmic emulsion [see CLINICAL PHARMACOLOGY], caution should be exercised when RESTASIS® is administered to a nursing woman.
The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for RESTASIS® and any potential adverse effects on the breast-fed child from cyclosporine.
Pediatric Use Safety and efficacy have not been established in pediatric patients below the age of 16.
Geriatric Use No overall difference in safety or effectiveness has been observed between elderly and younger patients.
Warnings & Precautions WARNINGS (See also BOXED WARNING) All Patients Cyclosporine, the active ingredient of Neoral®, can cause nephrotoxicity and hepatotoxicity.
The risk increases with increasing doses of cyclosporine.
Renal dysfunction including structural kidney damage is a potential consequence of Neoral® and therefore renal function must be monitored during therapy.
Care should be taken in using cyclosporine with nephrotoxic drugs.
(See PRECAUTIONS) Patients receiving Neoral® require frequent monitoring of serum creatinine.
(See Special Monitoring under DOSAGE AND ADMINISTRATION) Elderly patients should be monitored with particular care, since decreases in renal function also occur with age.
If patients are not properly monitored and doses are not properly adjusted, cyclosporine therapy can be associated with the occurrence of structural kidney damage and persistent renal dysfunction.
An increase in serum creatinine and BUN may occur during Neoral® therapy and reflect a reduction in the glomerular filtration rate.
Impaired renal function at any time requires close monitoring, and frequent dosage adjustment may be indicated.
The frequency and severity of serum creatinine elevations increase with dose and duration of cyclosporine therapy.
These elevations are likely to become more pronounced without dose reduction or discontinuation.
Because Neoral® is not bioequivalent to Sandimmune®, conversion from Neoral® to Sandimmune® using a 1:1 ratio (mg/kg/day) may result in lower cyclosporine blood concentrations.
Conversion from Neoral® to Sandimmune® should be made with increased monitoring to avoid the potential of underdosing.
Kidney, Liver, and Heart Transplant Nephrotoxicity Cyclosporine, the active ingredient of Neoral®, can cause nephrotoxicity and hepatotoxicity when used in high doses.
It is not unusual for serum creatinine and BUN levels to be elevated during cyclosporine therapy.
These elevations in renal transplant patients do not necessarily indicate rejection, and each patient must be fully evaluated before dosage adjustment is initiated.
Based on the historical Sandimmune® experience with oral solution, nephrotoxicity associated with cyclosporine had been noted in 25% of cases of renal transplantation, 38% of cases of cardiac transplantation, and 37% of cases of liver transplantation.
Mild nephrotoxicity was generally noted 2-3 months after renal transplant and consisted of an arrest in the fall of the pre-operative elevations of BUN and creatinine at a range of 35-45 mg/dl and 2.0-2.5 mg/dl respectively.
These elevations were often responsive to cyclosporine dosage reduction.
More overt nephrotoxicity was seen early after transplantation and was characterized by a rapidly rising BUN and creatinine.
Since these events are similar to renal rejection episodes, care must be taken to differentiate between them.
This form of nephrotoxicity is usually responsive to cyclosporine dosage reduction.
Although specific diagnostic criteria which reliably differentiate renal graft rejection from drug toxicity have not been found, a number of parameters have been significantly associated with one or the other.
It should be noted however, that up to 20% of patients may have simultaneous nephrotoxicity and rejection.

From 5%-15% of transplant recipients who have received cyclosporine will fail to show a reduction in rising serum creatinine despite a decrease or discontinuation of cyclosporine therapy.
Renal biopsies from these patients will demonstrate one or several of the following alterations: tubular vacuolization, tubular microcalcifications, peritubular capillary congestion, arteriolopathy, and a striped form of interstitial fibrosis with tubular atrophy.
Though none of these morphologic changes is entirely specific, a diagnosis of cyclosporine-associated structural nephrotoxicity requires evidence of these findings.
When considering the development of cyclosporine-associated nephropathy, it is noteworthy that several authors have reported an association between the appearance of interstitial fibrosis and higher cumulative doses or persistently high circulating trough levels of cyclosporine.
This is particularly true during the first 6 post-transplant months when the dosage tends to be highest and when, in kidney recipients, the organ appears to be most vulnerable to the toxic effects of cyclosporine.
Among other contributing factors to the development of interstitial fibrosis in these patients are prolonged perfusion time, warm ischemia time, as well as episodes of acute toxicity, and acute and chronic rejection.
The reversibility of interstitial fibrosis and its correlation to renal function have not yet been determined.
Reversibility of arteriolopathy has been reported after stopping cyclosporine or lowering the dosage.
Impaired renal function at any time requires close monitoring, and frequent dosage adjustment may be indicated.
In the event of severe and unremitting rejection, when rescue therapy with pulse steroids and monoclonal antibodies fail to reverse the rejection episode, it may be preferable to switch to alternative immunosuppressive therapy rather than increase the Neoral® dose to excessive levels.
Thrombotic Microangiopathy Occasionally patients have developed a syndrome of thrombocytopenia and microangiopathic hemolytic anemia which may result in graft failure.
The vasculopathy can occur in the absence of rejection and is accompanied by avid platelet consumption within the graft as demonstrated by Indium 111 labeled platelet studies.
Neither the pathogenesis nor the management of this syndrome is clear.
Though resolution has occurred after reduction or discontinuation of cyclosporine and 1) administration of streptokinase and heparin or 2) plasmapheresis, this appears to depend upon early detection with Indium 111 labeled platelet scans.
(See ADVERSE REACTIONS) Hyperkalemia Significant hyperkalemia (sometimes associated with hyperchloremic metabolic acidosis) and hyperuricemia have been seen occasionally in individual patients.
Hepatotoxicity Cases of hepatotoxicity and liver injury including cholestasis, jaundice, hepatitis, and liver failure have been reported in patients treated with cyclosporine.
Most reports included patients with significant comorbidities, underlying conditions and other confounding factors including infectious complications and comedications with hepatotoxic potential.
In some cases, mainly in transplant patients, fatal outcomes have been reported (see ADVERSE REACTIONS, Postmarketing Experience, Kidney, Liver and Heart Transplantation).
Hepatotoxicity, usually manifested by elevations in hepatic enzymes and bilirubin, was reported in patients treated with cyclosporine in clinical trials: 4% in renal transplantation, 7% in cardiac transplantation, and 4% in liver transplantation.
This was usually noted during the first month of therapy when high doses of cyclosporine were used.
The chemistry elevations usually decreased with a reduction in dosage.
Malignancies As in patients receiving other immunosuppressants, those patients receiving cyclosporine are at increased risk for development of lymphomas and other malignancies, particularly those of the skin.
Patients taking cyclosporine should be warned to avoid excess ultraviolet light exposure.
The increased risk appears related to the intensity and duration of immunosuppression rather than to the use of specific agents.
Because of the danger of oversuppression of the immune system resulting in increased risk of infection or malignancy, a treatment regimen containing multiple immunosuppressants should be used with caution.
Some malignancies may be fatal.
Transplant patients receiving cyclosporine are at increased risk for serious infection with fatal outcome.
Serious Infections Patients receiving immunosuppressants, including Neoral, are at increased risk of developing bacterial, viral, fungal, and protozoal infections, including opportunistic infections.
These infections may lead to serious, including fatal, outcomes [See BOXED WARNING, and ADVERSE REACTIONS].
Polyomavirus Infections Patients receiving immunosuppressants, including Neoral, are at increased risk for opportunistic infections, including polyomavirus infections.
Polyoma virus infections in transplant patients may have serious, and sometimes, fatal outcomes.
These include cases of JC virus-associated progressive multifocal leukoencephalopathy (PML), and polyoma virus-associated nephropathy (PVAN), especially due to BK virus infection, which have been observed in patients receiving cyclosporine.
PVAN is associated with serious outcomes, including deteriorating renal function and renal graft loss, (see ADVERSE REACTIONS/Postmarketing Experience, Kidney, Liver and Heart Transplantation).
Patient monitoring may help detect patients at risk for PVAN.
Cases of PML have been reported in patients treated with Neoral.
PML, which is sometimes fatal, commonly presents with hemiparesis, apathy, confusion, cognitive deficiencies and ataxia.
Risk factors for PML include treatment with immunosuppressant therapies and impairment of immune function.
In immunosuppressed patients, physicians should consider PML in the differential diagnosis in patients reporting neurological symptoms and consultation with a neurologist should be considered as clinically indicated.
Consideration should be given to reducing the total immunosuppression in transplant patients who develop PML or PVAN.
However, reduced immunosuppression may place the graft at risk.
Neurotoxicity There have been reports of convulsions in adult and pediatric patients receiving cyclosporine, particularly in combination with high dose methylprednisolone.
Encephalopathy has been described both in post-marketing reports and in the literature.
Manifestations include impaired consciousness, convulsions, visual disturbances (including blindness), loss of motor function, movement disorders and psychiatric disturbances.
In many cases, changes in the white matter have been detected using imaging techniques and pathologic specimens.
Predisposing factors such as hypertension, hypomagnesemia, hypocholesterolemia, high-dose corticosteroids, high cyclosporine blood concentrations, and graft-versus-host disease have been noted in many but not all of the reported cases.
The changes in most cases have been reversible upon discontinuation of cyclosporine, and in some cases improvement was noted after reduction of dose.
It appears that patients receiving liver transplant are more susceptible to encephalopathy than those receiving kidney transplant.
Another rare manifestation of cyclosporine-induced neurotoxicity, occurring in transplant patients more frequently than in other indications, is optic disc edema including papilloedema, with possible visual impairment, secondary to benign intracranial hypertension.
Care should be taken in using cyclosporine with nephrotoxic drugs.
(See PRECAUTIONS) Rheumatoid Arthritis Cyclosporine nephropathy was detected in renal biopsies of 6 out of 60 (10%) rheumatoid arthritis patients after the average treatment duration of 19 months.
Only one patient, out of these 6 patients, was treated with a dose ≤ 4 mg/kg/day.
Serum creatinine improved in all but one patient after discontinuation of cyclosporine.
The “maximal creatinine increase” appears to be a factor in predicting cyclosporine nephropathy.
There is a potential, as with other immunosuppressive agents, for an increase in the occurrence of malignant lymphomas with cyclosporine.
It is not clear whether the risk with cyclosporine is greater than that in rheumatoid arthritis patients or in rheumatoid arthritis patients on cytotoxic treatment for this indication.
Five cases of lymphoma were detected: four in a survey of approximately 2,300 patients treated with cyclosporine for rheumatoid arthritis, and another case of lymphoma was reported in a clinical trial.
Although other tumors (12 skin cancers, 24 solid tumors of diverse types, and 1 multiple myeloma) were also reported in this survey, epidemiologic analyses did not support a relationship to cyclosporine other than for malignant lymphomas.
Patients should be thoroughly evaluated before and during Neoral® treatment for the development of malignancies.
Moreover, use of Neoral® therapy with other immunosuppressive agents may induce an excessive immunosuppression which is known to increase the risk of malignancy.
Psoriasis (See also BOXED WARNINGS for Psoriasis) Since cyclosporine is a potent immunosuppressive agent with a number of potentially serious side effects, the risks and benefits of using Neoral® should be considered before treatment of patients with psoriasis.
Cyclosporine, the active ingredient in Neoral®, can cause nephrotoxicity and hypertension (see PRECAUTIONS) and the risk increases with increasing dose and duration of therapy.
Patients who may be at increased risk such as those with abnormal renal function, uncontrolled hypertension or malignancies, should not receive Neoral®.
Renal dysfunction is a potential consequence of Neoral® therefore renal function must be monitored during therapy.
Patients receiving Neoral® require frequent monitoring of serum creatinine.
(See Special Monitoring under DOSAGE AND ADMINISTRATION) Elderly patients should be monitored with particular care, since decreases in renal function also occur with age.
If patients are not properly monitored and doses are not properly adjusted, cyclosporine therapy can cause structural kidney damage and persistent renal dysfunction.
An increase in serum creatinine and BUN may occur during Neoral® therapy and reflects a reduction in the glomerular filtration rate.
Kidney biopsies from 86 psoriasis patients treated for a mean duration of 23 months with 1.2-7.6 mg/kg/day of cyclosporine showed evidence of cyclosporine nephropathy in 18/86 (21%) of the patients.
The pathology consisted of renal tubular atrophy and interstitial fibrosis.
On repeat biopsy of 13 of these patients maintained on various dosages of cyclosporine for a mean of 2 additional years, the number with cyclosporine induced nephropathy rose to 26/86 (30%).
The majority of patients (19/26) were on a dose of ≥ 5.0 mg/kg/day (the highest recommended dose is 4 mg/kg/day).
The patients were also on cyclosporine for greater than 15 months (18/26) and/or had a clinically significant increase in serum creatinine for greater than 1 month (21/26).
Creatinine levels returned to normal range in 7 of 11 patients in whom cyclosporine therapy was discontinued.
There is an increased risk for the development of skin and lymphoproliferative malignancies in cyclosporine-treated psoriasis patients.
The relative risk of malignancies is comparable to that observed in psoriasis patients treated with other immunosuppressive agents.
Tumors were reported in 32 (2.2%) of 1439 psoriasis patients treated with cyclosporine worldwide from clinical trials.
Additional tumors have been reported in 7 patients in cyclosporine postmarketing experience.
Skin malignancies were reported in 16 (1.1%) of these patients; all but 2 of them had previously received PUVA therapy.
Methotrexate was received by 7 patients.
UVB and coal tar had been used by 2 and 3 patients, respectively.
Seven patients had either a history of previous skin cancer or a potentially predisposing lesion was present prior to cyclosporine exposure.
Of the 16 patients with skin cancer, 11 patients had 18 squamous cell carcinomas and 7 patients had 10 basal cell carcinomas.
There were two lymphoproliferative malignancies; one case of non-Hodgkin's lymphoma which required chemotherapy, and one case of mycosis fungoides which regressed spontaneously upon discontinuation of cyclosporine.
There were four cases of benign lymphocytic infiltration: 3 regressed spontaneously upon discontinuation of cyclosporine, while the fourth regressed despite continuation of the drug.
The remainder of the malignancies, 13 cases (0.9%), involved various organs.
Patients should not be treated concurrently with cyclosporine and PUVA or UVB, other radiation therapy, or other immunosuppressive agents, because of the possibility of excessive immunosuppression and the subsequent risk of malignancies.
(See CONTRAINDICATIONS) Patients should also be warned to protect themselves appropriately when in the sun, and to avoid excessive sun exposure.
Patients should be thoroughly evaluated before and during treatment for the presence of malignancies remembering that malignant lesions may be hidden by psoriatic plaques.
Skin lesions not typical of psoriasis should be biopsied before starting treatment.
Patients should be treated with Neoral® only after complete resolution of suspicious lesions, and only if there are no other treatment options.
(See Special Monitoring for Psoriasis Patients) PRECAUTIONS General Hypertension Cyclosporine is the active ingredient of Neoral®.
Hypertension is a common side effect of cyclosporine therapy which may persist.
(See ADVERSE REACTIONS and DOSAGE AND ADMINISTRATION for monitoring recommendations) Mild or moderate hypertension is encountered more frequently than severe hypertension and the incidence decreases over time.
In recipients of kidney, liver, and heart allografts treated with cyclosporine, antihypertensive therapy may be required.
(See Special Monitoring of Rheumatoid Arthritis and Psoriasis Patients) However, since cyclosporine may cause hyperkalemia, potassium-sparing diuretics should not be used.
While calcium antagonists can be effective agents in treating cyclosporine-associated hypertension, they can interfere with cyclosporine metabolism.
(See DRUG INTERACTIONS) Vaccination During treatment with cyclosporine, vaccination may be less effective; and the use of live attenuated vaccines should be avoided.
Special Monitoring of Rheumatoid Arthritis Patients Before initiating treatment, a careful physical examination, including blood pressure measurements (on at least two occasions) and two creatinine levels to estimate baseline should be performed.
Blood pressure and serum creatinine should be evaluated every 2 weeks during the initial 3 months and then monthly if the patient is stable.
It is advisable to monitor serum creatinine and blood pressure always after an increase of the dose of nonsteroidal anti-inflammatory drugs and after initiation of new nonsteroidal anti-inflammatory drug therapy during Neoral® treatment.
If co-administered with methotrexate, CBC and liver function tests are recommended to be monitored monthly.
(See also PRECAUTIONS, General, Hypertension) In patients who are receiving cyclosporine, the dose of Neoral® should be decreased by 25%-50% if hypertension occurs.
If hypertension persists, the dose of Neoral® should be further reduced or blood pressure should be controlled with antihypertensive agents.
In most cases, blood pressure has returned to baseline when cyclosporine was discontinued.
In placebo-controlled trials of rheumatoid arthritis patients, systolic hypertension (defined as an occurrence of two systolic blood pressure readings > 140 mmHg) and diastolic hypertension (defined as two diastolic blood pressure readings > 90 mmHg) occurred in 33% and 19% of patients treated with cyclosporine, respectively.
The corresponding placebo rates were 22% and 8%.
Special Monitoring for Psoriasis Patients Before initiating treatment, a careful dermatological and physical examination, including blood pressure measurements (on at least two occasions) should be performed.
Since Neoral® is an immunosuppressive agent, patients should be evaluated for the presence of occult infection on their first physical examination and for the presence of tumors initially, and throughout treatment with Neoral®.
Skin lesions not typical for psoriasis should be biopsied before starting Neoral®.
Patients with malignant or premalignant changes of the skin should be treated with Neoral® only after appropriate treatment of such lesions and if no other treatment option exists.
Baseline laboratories should include serum creatinine (on two occasions), BUN, CBC, serum magnesium, potassium, uric acid, and lipids.
The risk of cyclosporine nephropathy is reduced when the starting dose is low (2.5 mg/kg/day), the maximum dose does not exceed 4.0 mg/kg/day, serum creatinine is monitored regularly while cyclosporine is administered, and the dose of Neoral® is decreased when the rise in creatinine is greater than or equal to 25% above the patient's pretreatment level.
The increase in creatinine is generally reversible upon timely decrease of the dose of Neoral® or its discontinuation.
Serum creatinine and BUN should be evaluated every 2 weeks during the initial 3 months of therapy and then monthly if the patient is stable.
If the serum creatinine is greater than or equal to 25% above the patient's pretreatment level, serum creatinine should be repeated within two weeks.
If the change in serum creatinine remains greater than or equal to 25% above baseline, Neoral® should be reduced by 25%-50%.
If at any time the serum creatinine increases by greater than or equal to 50% above pretreatment level, Neoral® should be reduced by 25%-50%.
Neoral® should be discontinued if reversibility (within 25% of baseline) of serum creatinine is not achievable after two dosage modifications.
It is advisable to monitor serum creatinine after an increase of the dose of nonsteroidal anti-inflammatory drug and after initiation of new nonsteroidal anti-inflammatory therapy during Neoral® treatment.
Blood pressure should be evaluated every 2 weeks during the initial 3 months of therapy and then monthly if the patient is stable, or more frequently when dosage adjustments are made.
Patients without a history of previous hypertension before initiation of treatment with Neoral®, should have the drug reduced by 25%-50% if found to have sustained hypertension.
If the patient continues to be hypertensive despite multiple reductions of Neoral®, then Neoral® should be discontinued.
For patients with treated hypertension, before the initiation of Neoral® therapy, their medication should be adjusted to control hypertension while on Neoral®.
Neoral® should be discontinued if a change in hypertension management is not effective or tolerable.
CBC, uric acid, potassium, lipids, and magnesium should also be monitored every 2 weeks for the first 3 months of therapy, and then monthly if the patient is stable or more frequently when dosage adjustments are made.
Neoral® dosage should be reduced by 25%-50% for any abnormality of clinical concern.
In controlled trials of cyclosporine in psoriasis patients, cyclosporine blood concentrations did not correlate well with either improvement or with side effects such as renal dysfunction.
Laboratory Tests In all patients treated with cyclosporine, renal and liver functions should be assessed repeatedly by measurement of serum creatinine, BUN, serum bilirubin, and liver enzymes.
Serum lipids, magnesium, and potassium should also be monitored.
Cyclosporine blood concentrations should be routinely monitored in transplant patients (see DOSAGE AND ADMINISTRATION, Blood Concentration Monitoring in Transplant Patients), and periodically monitored in rheumatoid arthritis patients.
Carcinogenesis, Mutagenesis, and Impairment of Fertility Carcinogenicity studies were carried out in male and female rats and mice.
In the 78-week mouse study, evidence of a statistically significant trend was found for lymphocytic lymphomas in females, and the incidence of hepatocellular carcinomas in mid-dose males significantly exceeded the control value.
In the 24-month rat study, pancreatic islet cell adenomas significantly exceeded the control rate in the low dose level.
Doses used in the mouse and rat studies were 0.01 to 0.16 times the clinical maintenance dose (6 mg/kg).
The hepatocellular carcinomas and pancreatic islet cell adenomas were not dose related.
Published reports indicate that co-treatment of hairless mice with UV irradiation and cyclosporine or other immunosuppressive agents shorten the time to skin tumor formation compared to UV irradiation alone.
Cyclosporine was not mutagenic in appropriate test systems.
Cyclosporine has not been found to be mutagenic/genotoxic in the Ames Test, the V79-HGPRT Test, the micronucleus test in mice and Chinese hamsters, the chromosome-aberration tests in Chinese hamster bone-marrow, the mouse dominant lethal assay, and the DNA-repair test in sperm from treated mice.
A recent study analyzing sister chromatid exchange (SCE) induction by cyclosporine using human lymphocytes in vitro gave indication of a positive effect (i.e., induction of SCE), at high concentrations in this system.
In two published research studies, rabbits exposed to cyclosporine in utero (10 mg/kg/day subcutaneously) demonstrated reduced numbers of nephrons, renal hypertrophy, systemic hypertension and progressive renal insufficiency up to 35 weeks of age.
Pregnant rats which received 12 mg/kg/day of cyclosporine intravenously (twice the recommended human intravenous dose) had fetuses with an increased incidence of ventricular septal defect.
These findings have not been demonstrated in other species and their relevance for humans is unknown.
No impairment in fertility was demonstrated in studies in male and female rats.
Widely distributed papillomatosis of the skin was observed after chronic treatment of dogs with cyclosporine at 9 times the human initial psoriasis treatment dose of 2.5 mg/kg, where doses are expressed on a body surface area basis.
This papillomatosis showed a spontaneous regression upon discontinuation of cyclosporine.
An increased incidence of malignancy is a recognized complication of immunosuppression in recipients of organ transplants and patients with rheumatoid arthritis and psoriasis.
The most common forms of neoplasms are non-Hodgkin's lymphoma and carcinomas of the skin.
The risk of malignancies in cyclosporine recipients is higher than in the normal, healthy population but similar to that in patients receiving other immunosuppressive therapies.
Reduction or discontinuance of immunosuppression may cause the lesions to regress.
In psoriasis patients on cyclosporine, development of malignancies, especially those of the skin has been reported.
(See WARNINGS) Skin lesions not typical for psoriasis should be biopsied before starting cyclosporine treatment.
Patients with malignant or premalignant changes of the skin should be treated with cyclosporine only after appropriate treatment of such lesions and if no other treatment option exists.
Pregnancy Pregnancy Category C Animal studies have shown reproductive toxicity in rats and rabbits.
Cyclosporine gave no evidence of mutagenic or teratogenic effects in the standard test systems with oral application (rats up to 17 mg/kg and rabbits up to 30 mg/kg per day orally.) Only at dose levels toxic to dams, were adverse effects seen in reproduction studies in rats.
Cyclosporine has been shown to be embryo- and fetotoxic in rats and rabbits following oral administration at maternally toxic doses.
Fetal toxicity was noted in rats at 0.8 and rabbits at 5.4 times the transplant doses in humans of 6.0 mg/kg, where dose corrections are based on body surface area.
Cyclosporine was embryo- and fetotoxic as indicated by increased pre- and postnatal mortality and reduced fetal weight together with related skeletal retardation.
There are no adequate and well-controlled studies in pregnant women therefore, Neoral® should not be used during pregnancy unless the potential benefit to the mother justifies the potential risk to the fetus.
In pregnant transplant recipients who are being treated with immunosuppressants the risk of premature birth is increased.
The following data represent the reported outcomes of 116 pregnancies in women receiving cyclosporine during pregnancy, 90% of whom were transplant patients, and most of whom received cyclosporine throughout the entire gestational period.
The only consistent patterns of abnormality were premature birth (gestational period of 28 to 36 weeks) and low birth weight for gestational age.
Sixteen fetal losses occurred.
Most of the pregnancies (85 of 100) were complicated by disorders; including, pre-eclampsia, eclampsia, premature labor, abruptio placentae, oligohydramnios, Rh incompatibility, and fetoplacental dysfunction.
Pre-term delivery occurred in 47%.
Seven malformations were reported in 5 viable infants and in 2 cases of fetal loss.
Twenty-eight percent of the infants were small for gestational age.
Neonatal complications occurred in 27%.
Therefore, the risks and benefits of using Neoral® during pregnancy should be carefully weighed.
A limited number of observations in children exposed to cyclosporine in utero are available, up to an age of approximately 7 years.
Renal function and blood pressure in these children were normal.
Because of the possible disruption of maternal-fetal interaction, the risk/benefit ratio of using Neoral® in psoriasis patients during pregnancy should carefully be weighed with serious consideration for discontinuation of Neoral®.
Nursing Mothers Cyclosporine passes into breast milk.
Mothers receiving treatment with Neoral® should not breast-feed.
Pediatric Use Although no adequate and well-controlled studies have been completed in children, transplant recipients as young as one year of age have received Neoral® with no unusual adverse effects.
The safety and efficacy of Neoral® treatment in children with juvenile rheumatoid arthritis or psoriasis below the age of 18 have not been established.
Geriatric Use In rheumatoid arthritis clinical trials with cyclosporine, 17.5% of patients were age 65 or older.
These patients were more likely to develop systolic hypertension on therapy, and more likely to show serum creatinine rises ≥ 50% above the baseline after 3-4 months of therapy.
Clinical studies of Neoral® in transplant and psoriasis patients did not include a sufficient number of subjects aged 65 and over to determine whether they respond differently from younger subjects.
Other reported clinical experiences have not identified differences in response between the elderly and younger patients.
In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
