CLINICAL PHARMACOLOGY Pharmacokinetics And Metabolism General Pharmacokinetic Characteristics Peak plasma concentrations of itraconazole are reached within 2 to 5 hours following oral administration. As a consequence of non-linear pharmacokinetics, itraconazole accumulates in plasma during multiple dosing. Steady-state concentrations are generally reached within about 15 days, with Cmax values of 0.5 μg/ml, 1.1 μg/ml and 2.0 μg/ml after oral administration of 100 mg once daily, 200 mg once daily and 200 mg b.i.d., respectively. The terminal half-life of itraconazole generally ranges from 16 to 28 hours after single dose and increases to 34 to 42 hours with repeated dosing. Once treatment is stopped, itraconazole plasma concentrations decrease to an almost undetectable concentration within 7 to 14 days, depending on the dose and duration of treatment. Itraconazole mean total plasma clearance following intravenous administration is 278 ml/min. Itraconazole clearance decreases at higher doses due to saturable hepatic metabolism. Absorption Itraconazole is rapidly absorbed after oral administration. Peak plasma concentrations of itraconazole are reached within 2 to 5 hours following an oral capsule dose. The observed absolute oral bioavailability of itraconazole is about 55%. The oral bioavailability of itraconazole is maximal when SPORANOX® (itraconazole) Capsules are taken immediately after a full meal. Absorption of itraconazole capsules is reduced in subjects with reduced gastric acidity, such as subjects taking medications known as gastric acid secretion suppressors (e.g., H2-receptor antagonists, proton pump inhibitors) or subjects with achlorhydria caused by certain diseases. (See DRUG INTERACTIONS.) Absorption of itraconazole under fasted conditions in these subjects is increased when SPORANOX® Capsules are administered with an acidic beverage (such as a non-diet cola). When SPORANOX® Capsules were administered as a single 200-mg dose under fasted conditions with non-diet cola after ranitidine pretreatment, a H2-receptor antagonist, itraconazole absorption was comparable to that observed when SPORANOX® Capsules were administered alone. (See DRUG INTERACTIONS.) Itraconazole exposure is lower with the Capsule formulation than with the Oral Solution when the same dose of drug is given. (See WARNINGS) Distribution Most of the itraconazole in plasma is bound to protein (99.8%), with albumin being the main binding component (99.6% for the hydroxy-metabolite). It has also a marked affinity for lipids. Only 0.2% of the itraconazole in plasma is present as free drug. Itraconazole is distributed in a large apparent volume in the body (>700 L), suggesting extensive distribution into tissues. Concentrations in lung, kidney, liver, bone, stomach, spleen and muscle were found to be two to three times higher than corresponding concentrations in plasma, and the uptake into keratinous tissues, skin in particular, up to four times higher. Concentrations in the cerebrospinal fluid are much lower than in plasma. Metabolism Itraconazole is extensively metabolized by the liver into a large number of metabolites. In vitro studies have shown that CYP3A4 is the major enzyme involved in the metabolism of itraconazole. The main metabolite is hydroxy-itraconazole, which has in vitro antifungal activity comparable to itraconazole; trough plasma concentrations of this metabolite are about twice those of itraconazole. Excretion Itraconazole is excreted mainly as inactive metabolites in urine (35%) and in feces (54%) within one week of an oral solution dose. Renal excretion of itraconazole and the active metabolite hydroxy-itraconazole account for less than 1% of an intravenous dose. Based on an oral radiolabeled dose, fecal excretion of unchanged drug ranges from 3% to 18% of the dose. As re-distribution of itraconazole from keratinous tissues appears to be negligible, elimination of itraconazole from these tissues is related to epidermal regeneration. Contrary to plasma, the concentration in skin persists for 2 to 4 weeks after discontinuation of a 4-week treatment and in nail keratin – where itraconazole can be detected as early as 1 week after start of treatment – for at least six months after the end of a 3-month treatment period. Special Populations Renal Impairment Limited data are available on the use of oral itraconazole in patients with renal impairment. A pharmacokinetic study using a single 200-mg oral dose of itraconazole was conducted in three groups of patients with renal impairment (uremia: n=7; hemodialysis: n=7; and continuous ambulatory peritoneal dialysis: n=5). In uremic subjects with a mean creatinine clearance of 13 mL/min. × 1.73 m², the exposure, based on AUC, was slightly reduced compared with normal population parameters. This study did not demonstrate any significant effect of hemodialysis or continuous ambulatory peritoneal dialysis on the pharmacokinetics of itraconazole (Tmax, Cmax, and AUC0-8h). Plasma concentration-versus-time profiles showed wide intersubject variation in all three groups. After a single intravenous dose, the mean terminal half-lives of itraconazole in patients with mild (defined in this study as CrCl 50-79 ml/min), moderate (defined in this study as CrCl 20-49 ml/min), and severe renal impairment (defined in this study as CrCl <20 ml/min) were similar to that in healthy subjects (range of means 42-49 hours vs 48 hours in renally impaired patients and healthy subjects, respectively). Overall exposure to itraconazole, based on AUC, was decreased in patients with moderate and severe renal impairment by approximately 30% and 40%, respectively, as compared with subjects with normal renal function. Data are not available in renally impaired patients during long-term use of itraconazole. Dialysis has no effect on the half-life or clearance of itraconazole or hydroxy-itraconazole. (See PRECAUTIONS and DOSAGE AND ADMINISTRATION.) Hepatic Impairment Itraconazole is predominantly metabolized in the liver. A pharmacokinetic study was conducted in 6 healthy and 12 cirrhotic subjects who were administered a single 100-mg dose of itraconazole as capsule. A statistically significant reduction in mean Cmax (47%) and a twofold increase in the elimination half-life (37±17 hours vs. 16±5 hours) of itraconazole were noted in cirrhotic subjects compared with healthy subjects. However, overall exposure to itraconazole, based on AUC, was similar in cirrhotic patients and in healthy subjects. Data are not available in cirrhotic patients during long-term use of itraconazole. (See CONTRAINDICATIONS, DRUG INTERACTIONS and DOSAGE AND ADMINISTRATION.) Decreased Cardiac Contractility When itraconazole was administered intravenously to anesthetized dogs, a dose-related negative inotropic effect was documented. In a healthy volunteer study of itraconazole intravenous infusion, transient, asymptomatic decreases in left ventricular ejection fraction were observed using gated SPECT imaging; these resolved before the next infusion, 12 hours later. If signs or symptoms of congestive heart failure appear during administration of SPORANOX® Capsules, SPORANOX® should be discontinued. (See BOXED WARNING, CONTRAINDICATIONS, WARNINGS, DRUG INTERACTIONS and ADVERSE REACTIONS: Post-marketing Experience for more information.) Microbiology Mechanism Of Action In vitro studies have demonstrated that itraconazole inhibits the cytochrome P450-dependent synthesis of ergosterol, which is a vital component of fungal cell membranes. Activity In Vitro And In Clinical Infections Itraconazole exhibits in vitro activity against Blastomyces dermatitidis, Histoplasma capsulatum, Histoplasma duboisii, Aspergillus flavus, Aspergillus fumigatus, and Trichophyton species (See INDICATIONS AND USAGE: Description of Clinical Studies). Correlation between minimum inhibitory concentration (MIC) results in vitro and clinical outcome has yet to be established for azole antifungal agents. Drug Resistance Isolates from several fungal species with decreased susceptibility to itraconazole have been isolated in vitro and from patients receiving prolonged therapy. Itraconazole is not active against Zygomycetes (e.g., Rhizopus spp., Rhizomucor spp., Mucor spp. and Absidia spp.), Fusarium spp., Scedosporium spp. and Scopulariopsis spp. Cross-Resistance Several in vitro studies have reported that some fungal clinical isolates with reduced susceptibility to one azole antifungal agent may also be less susceptible to other azole derivatives. The finding of cross-resistance is dependent on a number of factors, including the species evaluated, its clinical history, the particular azole compounds compared, and the type of susceptibility test that is performed. Studies (both in vitro and in vivo) suggest that the activity of amphotericin B may be suppressed by prior azole antifungal therapy. As with other azoles, itraconazole inhibits the 14C-demethylation step in the synthesis of ergosterol, a cell wall component of fungi. Ergosterol is the active site for amphotericin B. In one study the antifungal activity of amphotericin B against Aspergillus fumigatus infections in mice was inhibited by ketoconazole therapy. The clinical significance of test results obtained in this study is unknown. Description Of Clinical Studies Blastomycosis Analyses were conducted on data from two open-label, non-concurrently controlled studies (N=73 combined) in patients with normal or abnormal immune status. The median dose was 200 mg/day. A response for most signs and symptoms was observed within the first 2 weeks, and all signs and symptoms cleared between 3 and 6 months. Results of these two studies demonstrated substantial evidence of the effectiveness of itraconazole for the treatment of blastomycosis compared with the natural history of untreated cases. Histoplasmosis Analyses were conducted on data from two open-label, non-concurrently controlled studies (N=34 combined) in patients with normal or abnormal immune status (not including HIV-infected patients). The median dose was 200 mg/day. A response for most signs and symptoms was observed within the first 2 weeks, and all signs and symptoms cleared between 3 and 12 months. Results of these two studies demonstrated substantial evidence of the effectiveness of itraconazole for the treatment of histoplasmosis, compared with the natural history of untreated cases. Histoplasmosis In HIV-Infected Patients Data from a small number of HIV-infected patients suggested that the response rate of histoplasmosis in HIV-infected patients is similar to that of non-HIV-infected patients. The clinical course of histoplasmosis in HIV-infected patients is more severe and usually requires maintenance therapy to prevent relapse. Aspergillosis Analyses were conducted on data from an open-label, “single-patient-use” protocol designed to make itraconazole available in the U.S. for patients who either failed or were intolerant of amphotericin B therapy (N=190). The findings were corroborated by two smaller open-label studies (N=31 combined) in the same patient population. Most adult patients were treated with a daily dose of 200 to 400 mg, with a median duration of 3 months. Results of these studies demonstrated substantial evidence of effectiveness of itraconazole as a second-line therapy for the treatment of aspergillosis compared with the natural history of the disease in patients who either failed or were intolerant of amphotericin B therapy. Onychomycosis Of The Toenail Analyses were conducted on data from three double-blind, placebo-controlled studies (N=214 total; 110 given SPORANOX® Capsules) in which patients with onychomycosis of the toenails received 200 mg of SPORANOX® Capsules once daily for 12 consecutive weeks. Results of these studies demonstrated mycologic cure, defined as simultaneous occurrence of negative KOH plus negative culture, in 54% of patients. Thirty-five percent (35%) of patients were considered an overall success (mycologic cure plus clear or minimal nail involvement with significantly decreased signs) and 14% of patients demonstrated mycologic cure plus clinical cure (clearance of all signs, with or without residual nail deformity). The mean time to overall success was approximately 10 months. Twenty-one percent (21%) of the overall success group had a relapse (worsening of the global score or conversion of KOH or culture from negative to positive). Onychomycosis Of The Fingernail Analyses were conducted on data from a double-blind, placebo-controlled study (N=73 total; 37 given SPORANOX® Capsules) in which patients with onychomycosis of the fingernails received a 1-week course (pulse) of 200 mg of SPORANOX® Capsules b.i.d., followed by a 3-week period without SPORANOX®, which was followed by a second 1-week pulse of 200 mg of SPORANOX® Capsules b.i.d. Results demonstrated mycologic cure in 61% of patients. Fifty-six percent (56%) of patients were considered an overall success and 47% of patients demonstrated mycologic cure plus clinical cure. The mean time to overall success was approximately 5 months. None of the patients who achieved overall success relapsed.

INDICATIONS SPORANOX® (itraconazole) Capsules are indicated for the treatment of the following fungal infections in immunocompromised and non-immunocompromised patients: Blastomycosis, pulmonary and extrapulmonary Histoplasmosis, including chronic cavitary pulmonary disease and disseminated, non-meningeal histoplasmosis, and Aspergillosis, pulmonary and extrapulmonary, in patients who are intolerant of or who are refractory to amphotericin B therapy. Specimens for fungal cultures and other relevant laboratory studies (wet mount, histopathology, serology) should be obtained before therapy to isolate and identify causative organisms. Therapy may be instituted before the results of the cultures and other laboratory studies are known; however, once these results become available, antiinfective therapy should be adjusted accordingly. SPORANOX® Capsules are also indicated for the treatment of the following fungal infections in non-immunocompromised patients: Onychomycosis of the toenail, with or without fingernail involvement, due to dermatophytes (tinea unguium), and Onychomycosis of the fingernail due to dermatophytes (tinea unguium). Prior to initiating treatment, appropriate nail specimens for laboratory testing (KOH preparation, fungal culture, or nail biopsy) should be obtained to confirm the diagnosis of onychomycosis. (See CLINICAL PHARMACOLOGY: Special Populations, CONTRAINDICATIONS, WARNINGS, and ADVERSE REACTIONS: Post-marketing Experience for more information.) DOSAGE AND ADMINISTRATION SPORANOX® (itraconazole) Capsules should be taken with a full meal to ensure maximal absorption. SPORANOX® (itraconazole) Capsules must be swallowed whole. SPORANOX® Capsules is a different preparation than SPORANOX® Oral Solution and should not be used interchangeably. Treatment Of Blastomycosis And Histoplasmosis The recommended dose is 200 mg once daily (2 capsules). If there is no obvious improvement, or there is evidence of progressive fungal disease, the dose should be increased in 100-mg increments to a maximum of 400 mg daily. Doses above 200 mg/day should be given in two divided doses. Treatment Of Aspergillosis A daily dose of 200 to 400 mg is recommended. Treatment In Life-Threatening Situations In life-threatening situations, a loading dose should be used. Although clinical studies did not provide for a loading dose, it is recommended, based on pharmacokinetic data, that a loading dose of 200 mg (2 capsules) three times daily (600 mg/day) be given for the first 3 days of treatment. Treatment should be continued for a minimum of three months and until clinical parameters and laboratory tests indicate that the active fungal infection has subsided. An inadequate period of treatment may lead to recurrence of active infection. SPORANOX® Capsules and SPORANOX® Oral Solution should not be used interchangeably. Only the oral solution has been demonstrated effective for oral and/or esophageal candidiasis. Treatment Of Onychomycosis Toenails with or without fingernail involvement: The recommended dose is 200 mg (2 capsules) once daily for 12 consecutive weeks. Treatment Of Onychomycosis Fingernails only: The recommended dosing regimen is 2 treatment pulses, each consisting of 200 mg (2 capsules) b.i.d. (400 mg/day) for 1 week. The pulses are separated by a 3-week period without SPORANOX®. Use In Patients With Renal Impairment Limited data are available on the use of oral itraconazole in patients with renal impairment. Caution should be exercised when this drug is administered in this patient population. (See CLINICAL PHARMACOLOGY: Special Populations and PRECAUTIONS.)

PATIENT INFORMATION SPORANOX® (itraconazole) Capsules 100 mg This summary contains important information about SPORANOX® (SPOR-ah-nox). This information is for patients who have been prescribed SPORANOX® to treat fungal nail infections. If your doctor prescribed SPORANOX® for medical problems other than fungal nail infections, ask your doctor if there is any information in this summary that does not apply to you. Read this information carefully each time you start to use SPORANOX®. This information does not take the place of discussion between you and your doctor. Only your doctor can decide if SPORANOX® is the right treatment for you. If you do not understand some of this information or have any questions, talk with your doctor or pharmacist. WHAT IS THE MOST IMPORTANT INFORMATION I SHOULD KNOW ABOUT SPORANOX®? SPORANOX® is used to treat fungal nail infections. However, SPORANOX® is not for everyone. Do not take SPORANOX® for fungal nail infections if you have had heart failure, including congestive heart failure. You should not take SPORANOX® if you are taking certain medicines that could lead to serious or life-threatening medical problems. (See “Who Should Not Take SPORANOX®?” below.) If you have had heart, lung, liver, kidney or other serious health problems, ask your doctor if it is safe for you to take SPORANOX®. WHAT HAPPENS IF I HAVE A FUNGAL NAIL INFECTION? Anyone can have a fungal nail infection, but it is usually found in adults. When a fungus infects the tip or sides of a nail, the infected part of the nail may turn yellow or brown. If not treated, the fungus may spread under the nail towards the cuticle. If the fungus spreads, more of the nail may change color, may become thick or brittle, and the tip of the nail may become raised. In some patients, this can cause pain and discomfort. WHAT IS SPORANOX®? SPORANOX® is a prescription medicine used to treat fungal infections of the toenails and fingernails. It is also used to treat some types of fungal infections in other areas of your body. We do not know if SPORANOX® works in children with fungal nail infections or if it is safe for children to take. SPORANOX® comes in the form of capsules and liquid (oral solution). The capsule and liquid forms work differently, so you should not use one in place of the other. This Patient Information discusses only the capsule form of SPORANOX®. You will get these capsules in a medicine bottle or a SPORANOX PulsePak®. The PulsePak® contains 28 capsules for treatment of your fungal nail infection. SPORANOX® goes into your bloodstream and travels to the source of the infection underneath the nail so that it can fight the infection there. Improved nails may not be obvious for several months after the treatment period is finished because it usually takes about 6 months to grow a new fingernail and 12 months to grow a new toenail. WHO SHOULD NOT TAKE SPORANOX®? SPORANOX® is not for everyone. Your doctor will decide if SPORANOX® is the right treatment for you. Some patients should not take SPORANOX® because they may have certain health problems or may be taking certain medicines that could lead to serious or life-threatening medical problems. Tell your doctor and pharmacist the name of all the prescription and non-prescription medicines you are taking, including dietary supplements and herbal remedies. Also tell your doctor about any other medical conditions you have had, especially heart, lung, liver or kidney conditions; or if you have cystic fibrosis, or have had an allergic reaction to SPORANOX® or any other antifungal medicines. Never take SPORANOX® if you: have had heart failure, including congestive heart failure. are taking any of the medicines listed below. Dangerous or even life-threatening side effects could result: avanafil (such as Stendra™) cisapride (such as Propulsid®) colchicine (such as Colcrys™) [if you also have pre-existing kidney or liver impairment] disopyramide (such as Norpace®) dofetilide (such as Tikosyn™) dronedarone (such as Multaq®) eliglustat (such as Cerdelga™) [if you know you do not break down drugs that are broken down by the enzyme CYP 2D6] eplerenone (such as Inspra®) ergot alkaloids (such as Migranal®, Ergonovine, Cafergot®, Methergine®) felodipine (such as Plendil®) fesoterodine (such as Toviaz®) [if you also have pre-existing kidney or liver impairment] irinotecan (such as Camptosar®) isavuconazole (such as Cresemba®) ivabradine (such as Corlanor®) lomitapide (such as Juxtapid™) lovastatin (such as Mevacor®, Advicor®, Altocor™) lurasidone (such as Latuda®) methadone (such as Dolophine®) midazolam (such as Versed®) naloxegol (such as Movantik®) nisoldipine (such as Sular®) pimozide (such as Orap®) quinidine (such as Cardioquin®, Quinaglute®, Quinidex®) ranolazine (such as Ranexa®) simvastatin (such as Zocor®) solifenacin (such as Vesicare®) [if you also have pre-existing kidney or liver impairment] ticagrelor (such as Brilinta®) triazolam (such as Hacion®) have ever had an allergic reaction to itraconazole. Taking SPORANOX® with certain other medicines may lead to serious or life-threatening medical problems. Tell your doctor and pharmacist the name of all the prescription and non-prescription medicines you are taking, including dietary supplements and herbal remedies. Your doctor will decide if SPORANOX® is the right treatment for you. WHAT SHOULD I KNOW ABOUT SPORANOX® AND PREGNANCY OR BREAST FEEDING? Never take SPORANOX® if you have a fungal nail infection and are pregnant or planning to become pregnant within 2 months after you have finished your treatment. If you are able to become pregnant, you should use effective birth control during SPORANOX® treatment and for 2 months after finishing treatment. Ask your doctor about effective types of birth control. If you are breast-feeding, talk with your doctor about whether you should take SPORANOX®. HOW SHOULD I TAKE SPORANOX®? Always take SPORANOX® Capsules during or right after a full meal. Your doctor will decide the right dose for you. Depending on your infection, you will take SPORANOX® once a day for 12 weeks, or twice a day for 1 week in a “pulse” dosing schedule. You will receive either a bottle of capsules or a PulsePak®. Do not skip any doses. Be sure to finish all your SPORANOX® as prescribed by your doctor. If you have ever had liver problems, your doctor should do a blood test to check your condition. If you haven't had liver problems, your doctor may recommend blood tests to check the condition of your liver because patients taking SPORANOX® can develop liver problems. SPORANOX® can sometimes cause dizziness or blurred/double vision. If you have these symptoms, do not drive or use machines. If you forget to take or miss doses of SPORANOX®, ask your doctor what you should do with the missed doses. THE SPORANOX PulsePak® If you use the PulsePak®, you will take SPORANOX® for 1 week and then take no SPORANOX® for the next 3 weeks before repeating the 1-week treatment. This is called “pulse dosing.” The SPORANOX PulsePak® contains enough medicine for one “pulse” (1 week of treatment). The SPORANOX PulsePak® comes with special instructions. It contains 7 pouches-one for each day of treatment. Inside each pouch is a card containing 4 capsules. Looking at the back of the card, fold it back along the dashed line and peel away the backing so that you can remove 2 capsules. Take 2 capsules in the morning and 2 capsules in the evening. This means you will take 4 capsules a day for 7 days. At the end of 7 days, you will have taken all of the capsules in the PulsePak® box. After you finish the PulsePak®, do not take any SPORANOX® for the next 3 weeks. Even though you are not taking any capsules during this time, SPORANOX® keeps working inside your nails to help fight the fungal infection. You will need more than one “pulse” to treat your fungal nail infection. When your doctor prescribes another pulse treatment, be sure to get your refill before the end of week 4. SPORANOX® Pulse Dosing Take 2 SPORANOX® capsules twice a day for 1 week Day 1 Day 2 Day 3 Day 4 Day 5 Day 6 Day 7 AM PM AM PM AM PM AM PM AM PM AM PM AM PM Week 1 ” ” ” ” ” ” ” ” ” ” ” ” ” ” Week 2 For the next 3 weeks, do not take any SPORANOX® capsules. Remember to get a refill before the end of Week 4 when your doctor prescribes another PulsePak® . Week 3 Week 4 WHAT ARE THE POSSIBLE SIDE EFFECTS OF SPORANOX®? The most common side effects include: headache, and digestive system problems (such as nausea, and abdominal pain). Stop SPORANOX® and call your doctor or get medical assistance right away if you have a severe allergic reaction. Symptoms of an allergic reaction may include skin rash, itching, hives, shortness of breath or difficulty breathing, and/or swelling of the face. Very rarely, an oversensitivity to sunlight, a tingling sensation in the limbs or a severe skin disorder can occur. If any of these symptoms occur, stop taking SPORANOX® and contact your doctor. Stop SPORANOX® and call your doctor right away if you develop shortness of breath; have unusual swelling of your feet, ankles or legs; suddenly gain weight; are unusually tired; cough up white or pink phlegm; have unusual fast heartbeats; or begin to wake up at night. In rare cases, patients taking SPORANOX® could develop serious heart problems, and these could be warning signs of heart failure. Stop SPORANOX® and call your doctor right away if you become unusually tired; lose your appetite; or develop nausea, abdominal pain, or vomiting, a yellow color to your skin or eyes, or dark colored urine or pale stools (bowel movements). In rare cases, patients taking SPORANOX® could develop serious liver problems and these could be warning signs. Stop SPORANOX® and call your doctor right away if you experience any hearing loss symptoms. In very rare cases, patients taking SPORANOX® have reported temporary or permanent hearing loss. Call your doctor right away if you develop tingling or numbness in your extremities (hands or feet), if your vision gets blurry or you see double, if you hear a ringing in your ears, if you lose the ability to control your urine or urinate much more than usual. Additional possible side effects include upset stomach, vomiting, constipation, fever, inflammation of the pancreas, menstrual disorder, erectile dysfunction, dizziness, muscle pain, painful joints, unpleasant taste, or hair loss. These are not all the side effects of SPORANOX®. Your doctor or pharmacist can give you a more complete list. WHAT SHOULD I DO IF I TAKE AN OVERDOSE OF SPORANOX®? If you think you took too much SPORANOX®, call your doctor or local poison control center, or go to the nearest hospital emergency room right away. HOW SHOULD I STORE SPORANOX®? Keep all medicines, including SPORANOX®, out of the reach of children. Store SPORANOX® Capsules and the PulsePak® at room temperature in a dry place away from light. GENERAL ADVICE ABOUT SPORANOX® Medicines are sometimes prescribed for conditions that are not mentioned in patient information leaflets. Do not use SPORANOX® for a condition for which it was not prescribed. Do not give SPORANOX® to other people, even if they have the same symptoms you have. It may harm them. This leaflet summarizes the most important information about SPORANOX®. If you would like more information, talk with your doctor. You can ask your doctor or pharmacist for information about SPORANOX® that is written for health professionals or you can call 1-800-526-7736. This patient information has been approved by the U.S. Food and Drug Administration.

OVERDOSE Itraconazole is not removed by dialysis. In the event of accidental overdosage, supportive measures should be employed. Activated charcoal may be given if considered appropriate. In general, adverse events reported with overdose have been consistent with adverse drug reactions already listed in this package insert for itraconazole. (See ADVERSE REACTIONS.) CONTRAINDICATIONS Congestive Heart Failure SPORANOX® (itraconazole) Capsules should not be administered for the treatment of onychomycosis in patients with evidence of ventricular dysfunction such as congestive heart failure (CHF) or a history of CHF. (See BOXED WARNING, WARNINGS, DRUG INTERACTIONS-Calcium Channel Blockers, ADVERSE REACTIONS: Post-marketing Experience, and CLINICAL PHARMACOLOGY: Special Populations.) Drug Interactions Coadministration of a number of CYP3A4 substrates are contraindicated with SPORANOX®. Plasma concentrations increase for the following drugs: levaceytlmethadol (levomethadyl), methadone, disopyramide, dofetilide, dronedarone, quinidine, isavuconazole, ergot alkaloids (such as dihydroergotamine, ergometrine (ergonovine), ergotamine, methylergometrine (methylergonovine)), irinotecan, lurasidone, oral midazolam, pimozide, triazolam, felodipine, nisoldipine, ivabradine, ranolazine, eplerenone, cisapride, naloxegol, lomitapide, lovastatin, simvastatin, avanafil, ticagrelor. In addition, coadministration with colchicine, fesoterodine and solifenacin is contraindicated in subjects with varying degrees of renal or hepatic impairment, and coadministration with eliglustat is contraindicated in subjects that are poor or intermediate metabolizers of CYP2D6 and in subjects taking strong or moderate CYP2D6 inhibitors. (See DRUG INTERACTIONS Section for specific examples.) This increase in drug concentrations caused by coadministration with itraconazole may increase or prolong both the pharmacologic effects and/or adverse reactions to these drugs. For example, increased plasma concentrations of some of these drugs can lead to QT prolongation and ventricular tachyarrhythmias including occurrences of torsade de pointes, a potentially fatal arrhythmia. Specific examples are listed in DRUG INTERACTIONS. SPORANOX® should not be administered for the treatment of onychomycosis to pregnant patients or to women contemplating pregnancy. SPORANOX® is contraindicated for patients who have shown hypersensitivity to itraconazole. There is limited information regarding cross-hypersensitivity between itraconazole and other azole antifungal agents. Caution should be used when prescribing SPORANOX® to patients with hypersensitivity to other azoles.

SIDE EFFECTS 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 clinical practice. SPORANOX® has been associated with rare cases of serious hepatotoxicity, including liver failure and death. Some of these cases had neither pre-existing liver disease nor a serious underlying medical condition. If clinical signs or symptoms develop that are consistent with liver disease, treatment should be discontinued and liver function testing performed. The risks and benefits of SPORANOX® use should be reassessed. (See WARNINGS: Hepatic Effects and PRECAUTIONS: Hepatotoxicity and PATIENT INFORMATION.) Adverse Events In The Treatment Of Systemic Fungal Infections Adverse event data were derived from 602 patients treated for systemic fungal disease in U.S. clinical trials who were immunocompromised or receiving multiple concomitant medications. Treatment was discontinued in 10.5% of patients due to adverse events. The median duration before discontinuation of therapy was 81 days (range: 2 to 776 days). The table lists adverse events reported by at least 1% of patients.

The following adverse events led to temporary or permanent discontinuation of therapy. Table 5: Clinical Trials of Onychomycosis of the Fingernail: Adverse Events Leading to Temporary or Permanent Discontinuation of Therapy Adverse Event Incidence (%) Itraconazole (N=37) Rash/Pruritus 3 Hypertriglyceridemia 3 The following adverse events occurred with an incidence of greater than or equal to 1% (N=37): headache: 8%; pruritus, nausea, rhinitis: 5%; rash, bursitis, anxiety, depression, constipation, abdominal pain, dyspepsia, ulcerative stomatitis, gingivitis, hypertriglyceridemia, sinusitis, fatigue, malaise, pain, injury: 3%. Adverse Events Reported From Other Clinical Trials In addition, the following adverse drug reaction was reported in patients who participated in SPORANOX® Capsules clinical trials: Hepatobiliary Disorders: hyperbilirubinemia. The following is a list of additional adverse drug reactions associated with itraconazole that have been reported in clinical trials of SPORANOX® Oral Solution and itraconazole IV excluding the adverse reaction term “Injection site inflammation” which is specific to the injection route of administration: Cardiac Disorders: cardiac failure, left ventricular failure, tachycardia; General Disorders and Administration Site Conditions: face edema, chest pain, chills; Hepatobiliary Disorders: hepatic failure, jaundice; Investigations: alanine aminotransferase increased, aspartate aminotransferase increased, blood alkaline phosphatase increased, blood lactate dehydrogenase increased, blood urea increased, gamma-glutamyltransferase increased, urine analysis abnormal; Metabolism and Nutrition Disorders: hyperglycemia, hyperkalemia, hypomagnesemia; Psychiatric Disorders: confusional state; Renal and Urinary Disorders: renal impairment; Respiratory, Thoracic and Mediastinal Disorders: dysphonia, cough; Skin and Subcutaneous Tissue Disorders: rash erythematous, hyperhidrosis; Vascular Disorders: hypotension Post-marketing Experience Adverse drug reactions that have been first identified during post-marketing experience with SPORANOX® (all formulations) are listed in the table below. Because these reactions are reported voluntarily from a population of uncertain size, reliably estimating their frequency or establishing a causal relationship to drug exposure is not always possible. Table 6: Postmarketing Reports of Adverse Drug Reactions Blood and Lymphatic System Disorders: Leukopenia, neutropenia, thrombocytopenia Immune System Disorders: Anaphylaxis; anaphylactic, anaphylactoid and allergic reactions; serum sickness; angioneurotic edema Nervous System Disorders: Peripheral neuropathy, paresthesia, hypoesthesia, tremor Visual disturbances, including vision blurred and Eye Disorders: diplopia Ear and Labyrinth Disorders: Transient or permanent hearing loss Cardiac Disorders: Congestive heart failure Respiratory, Thoracic and Mediastinal Disorders: Pulmonary edema, dyspnea Gastrointestinal Disorders: Pancreatitis, dysgeusia Hepatobiliary Disorders: Serious hepatotoxicity (including some cases of fatal acute liver failure), hepatitis Skin and Subcutaneous Tissue Disorders: Toxic epidermal necrolysis, Stevens-Johnson syndrome, acute generalized exanthematous pustulosis, erythema multiforme, exfoliative dermatitis, leukocytoclastic vasculitis, alopecia, photosensitivity, urticaria Musculoskeletal and Connective Tissue Disorders: Arthralgia Renal and Urinary Disorders: Urinary incontinence, pollakiuria Reproductive System and Breast Disorders: Erectile dysfunction General Disorders and Administration Site Conditions: Peripheral edema Investigations: Blood creatine phosphokinase increased There is limited information on the use of SPORANOX® during pregnancy. Cases of congenital abnormalities including skeletal, genitourinary tract, cardiovascular and ophthalmic malformations as well as chromosomal and multiple malformations have been reported during post-marketing experience. A causal relationship with SPORANOX® has not been established. (See CLINICAL PHARMACOLOGY: Special Populations, CONTRAINDICATIONS, WARNINGS, and DRUG INTERACTIONS for more information.) DRUG INTERACTIONS Effect Of SPORANOX® On Other Drugs Itraconazole and its major metabolite, hydroxy-itraconazole, are potent CYP3A4 inhibitors. Itraconazole is an inhibitor of the drug transporters P-glycoprotein and breast cancer resistance protein (BCRP). Consequently, SPORANOX® has the potential to interact with many concomitant drugs resulting in either increased or sometimes decreased concentrations of the concomitant drugs. Increased concentrations may increase the risk of adverse reactions associated with the concomitant drug which can be severe or life-threatening in some cases (e.g., QT prolongation, Torsade de Pointes, respiratory depression, hepatic adverse reactions, hypersensitivity reactions, myelosuppression, hypotension, seizures, angioedema, atrial fibrillation, bradycardia, priapism). Reduced concentrations of concomitant drugs may reduce their efficacy. Table 1 lists examples of drugs that may have their concentrations affected by itraconazole, but is not a comprehensive list. Refer to the approved product labeling to become familiar with the interaction pathways, risk potential, and specific actions to be taken with regards to each concomitant drug prior to initiating therapy with SPORANOX®. Although many of the clinical drug interactions in Table 1 are based on information with a similar azole antifungal, ketoconazole, these interactions are expected to occur with SPORANOX®.

Other substances that either share this metabolic pathway or modify CYP3A4 activity may influence the pharmacokinetics of itraconazole. Some concomitant drugs have the potential to interact with SPORANOX® resulting in either increased or sometimes decreased concentrations of SPORANOX®. Increased concentrations may increase the risk of adverse reactions associated with SPORANOX®. Decreased concentrations may reduce SPORANOX® efficacy. Table 2 lists examples of drugs that may affect itraconazole concentrations, but is not a comprehensive list. Refer to the approved product labeling to become familiar with the interaction pathways, risk potential and specific actions to be taken with regards to each concomitant drug prior to initiating therapy with SPORANOX®.

Pediatric Population Interaction studies have only been performed in adults.

WARNINGS Hepatic Effects SPORANOX® has been associated with rare cases of serious hepatotoxicity, including liver failure and death. Some of these cases had neither pre-existing liver disease nor a serious underlying medical condition, and some of these cases developed within the first week of treatment. If clinical signs or symptoms develop that are consistent with liver disease, treatment should be discontinued and liver function testing performed. Continued SPORANOX® use or reinstitution of treatment with SPORANOX® is strongly discouraged unless there is a serious or life-threatening situation where the expected benefit exceeds the risk. (See PATIENT INFORMATION and ADVERSE REACTIONS.) Cardiac Dysrhythmias Life-threatening cardiac dysrhythmias and/or sudden death have occurred in patients using drugs such as cisapride, pimozide, methadone, or quinidine concomitantly with SPORANOX® and/or other CYP3A4 inhibitors. Concomitant administration of these drugs with SPORANOX® is contraindicated. (See BOXED WARNING, CONTRAINDICATIONS, and DRUG INTERACTIONS.) Cardiac Disease SPORANOX® Capsules should not be administered for the treatment of onychomycosis in patients with evidence of ventricular dysfunction such as congestive heart failure (CHF) or a history of CHF. SPORANOX® Capsules should not be used for other indications in patients with evidence of ventricular dysfunction unless the benefit clearly outweighs the risk. For patients with risk factors for congestive heart failure, physicians should carefully review the risks and benefits of SPORANOX® therapy. These risk factors include cardiac disease such as ischemic and valvular disease; significant pulmonary disease such as chronic obstructive pulmonary disease; and renal failure and other edematous disorders. Such patients should be informed of the signs and symptoms of CHF, should be treated with caution, and should be monitored for signs and symptoms of CHF during treatment. If signs or symptoms of CHF appear during administration of SPORANOX® Capsules, discontinue administration. Itraconazole has been shown to have a negative inotropic effect. When itraconazole was administered intravenously to anesthetized dogs, a dose-related negative inotropic effect was documented. In a healthy volunteer study of itraconazole intravenous infusion, transient, asymptomatic decreases in left ventricular ejection fraction were observed using gated SPECT imaging; these resolved before the next infusion, 12 hours later. SPORANOX® has been associated with reports of congestive heart failure. In post-marketing experience, heart failure was more frequently reported in patients receiving a total daily dose of 400 mg although there were also cases reported among those receiving lower total daily doses. Calcium channel blockers can have negative inotropic effects which may be additive to those of itraconazole. In addition, itraconazole can inhibit the metabolism of calcium channel blockers. Therefore, caution should be used when co-administering itraconazole and calcium channel blockers due to an increased risk of CHF. Concomitant administration of SPORANOX® and felodipine or nisoldipine is contraindicated. Cases of CHF, peripheral edema, and pulmonary edema have been reported in the post-marketing period among patients being treated for onychomycosis and/or systemic fungal infections. (See CLINICAL PHARMACOLOGY: Special Populations, CONTRAINDICATIONS, DRUG INTERACTIONS, and ADVERSE REACTIONS: Post-marketing Experience for more information.) Interaction Potential SPORANOX® has a potential for clinically important drug interactions. Coadministration of specific drugs with itraconazole may result in changes in efficacy of itraconazole and/or the coadministered drug, life-threatening effects and/or sudden death. Drugs that are contraindicated, not recommended or recommended for use with caution in combination with itraconazole are listed in PRECAUTIONS: Drug Interactions. Interchangeability SPORANOX® (itraconazole) Capsules and SPORANOX® Oral Solution should not be used interchangeably. This is because drug exposure is greater with the Oral Solution than with the Capsules when the same dose of drug is given. In addition, the topical effects of mucosal exposure may be different between the two formulations. Only the Oral Solution has been demonstrated effective for oral and/or esophageal candidiasis. PRECAUTIONS General SPORANOX® (itraconazole) Capsules should be administered after a full meal. (See CLINICAL PHARMACOLOGY: Pharmacokinetics and Metabolism). Under fasted conditions, itraconazole absorption was decreased in the presence of decreased gastric acidity. The absorption of itraconazole may be decreased with the concomitant administration of antacids or gastric acid secretion suppressors. Studies conducted under fasted conditions demonstrated that administration with 8 ounces of a non-diet cola beverage resulted in increased absorption of itraconazole in AIDS patients with relative or absolute achlorhydria. This increase relative to the effects of a full meal is unknown. (See CLINICAL PHARMACOLOGY: Pharmacokinetics and Metabolism). Hepatotoxicity Rare cases of serious hepatotoxicity have been observed with SPORANOX® treatment, including some cases within the first week. It is recommended that liver function monitoring be considered in all patients receiving SPORANOX®. Treatment should be stopped immediately and liver function testing should be conducted in patients who develop signs and symptoms suggestive of liver dysfunction. Neuropathy If neuropathy occurs that may be attributable to SPORANOX® Capsules, the treatment should be discontinued. Cystic Fibrosis If a cystic fibrosis patient does not respond to SPORANOX® Capsules, consideration should be given to switching to alternative therapy. For more information concerning the use of itraconazole in cystic fibrosis patients see the prescribing information for SPORANOX® Oral Solution. Hearing Loss Transient or permanent hearing loss has been reported in patients receiving treatment with itraconazole. Several of these reports included concurrent administration of quinidine which is contraindicated (See BOXED WARNING:Drug Interactions, CONTRAINDICATIONS: Drug Interactions and DRUG INTERACTIONS). The hearing loss usually resolves when treatment is stopped, but can persist in some patients. Information For Patients The topical effects of mucosal exposure may be different between the SPORANOX® Capsules and Oral Solution. Only the Oral Solution has been demonstrated effective for oral and/or esophageal candidiasis. SPORANOX® Capsules should not be used interchangeably with SPORANOX® Oral Solution. Instruct patients to take SPORANOX® Capsules with a full meal. SPORANOX® Capsules must be swallowed whole. Instruct patients about the signs and symptoms of congestive heart failure, and if these signs or symptoms occur during SPORANOX® administration, they should discontinue SPORANOX® and contact their healthcare provider immediately. Instruct patients to stop SPORANOX® treatment immediately and contact their healthcare provider if any signs and symptoms suggestive of liver dysfunction develop. Such signs and symptoms may include unusual fatigue, anorexia, nausea and/or vomiting, jaundice, dark urine, or pale stools. Instruct patients to contact their physician before taking any concomitant medications with itraconazole to ensure there are no potential drug interactions. Instruct patients that hearing loss can occur with the use of itraconazole. The hearing loss usually resolves when treatment is stopped, but can persist in some patients. Advise patients to discontinue therapy and inform their physicians if any hearing loss symptoms occur. Instruct patients that dizziness or blurred/double vision can sometimes occur with itraconazole. Advise patients that if they experience these events, they should not drive or use machines. Carcinogenesis, Mutagenesis, And Impairment Of Fertility Itraconazole showed no evidence of carcinogenicity potential in mice treated orally for 23 months at dosage levels up to 80.mg/kg/day (approximately 10 times the maximum recommended human dose [MRHD]). Male rats treated with 25.mg/kg/day (3.1 times the MRHD) had a slightly increased incidence of soft tissue sarcoma. These sarcomas may have been a consequence of hypercholesterolemia, which is a response of rats, but not dogs or humans, to chronic itraconazole administration. Female rats treated with 50 mg/kg/day (6.25 times the MRHD) had an increased incidence of squamous cell carcinoma of the lung (2/50) as compared to the untreated group. Although the occurrence of squamous cell carcinoma in the lung is extremely uncommon in untreated rats, the increase in this study was not statistically significant. Itraconazole produced no mutagenic effects when assayed in DNA repair test (unscheduled DNA synthesis) in primary rat hepatocytes, in Ames tests with Salmonella typhimurium (6 strains) and Escherichia coli, in the mouse lymphoma gene mutation tests, in a sex-linked recessive lethal mutation (Drosophila melanogaster) test, in chromosome aberration tests in human lymphocytes, in a cell transformation test with C3H/10T½ C18 mouse embryo fibroblasts cells, in a dominant lethal mutation test in male and female mice, and in micronucleus tests in mice and rats. Itraconazole did not affect the fertility of male or female rats treated orally with dosage levels of up to 40.mg/kg/day (5 times the MRHD), even though parental toxicity was present at this dosage level. More severe signs of parental toxicity, including death, were present in the next higher dosage level, 160 mg/kg/day (20 times the MRHD). Pregnancy Teratogenic Effects Pregnancy Category C Itraconazole was found to cause a dose-related increase in maternal toxicity, embryotoxicity, and teratogenicity in rats at dosage levels of approximately 40-160 mg/kg/day (5-20 times the MRHD), and in mice at dosage levels of approximately 80 mg/kg/day (10 times the MRHD). Itraconazole has been shown to cross the placenta in a rat model. In rats, the teratogenicity consisted of major skeletal defects; in mice, it consisted of encephaloceles and/or macroglossia. There are no studies in pregnant women. SPORANOX® should be used for the treatment of systemic fungal infections in pregnancy only if the benefit outweighs the potential risk. SPORANOX® should not be administered for the treatment of onychomycosis to pregnant patients or to women contemplating pregnancy. SPORANOX® should not be administered to women of childbearing potential for the treatment of onychomycosis unless they are using effective measures to prevent pregnancy and they begin therapy on the second or third day following the onset of menses. Effective contraception should be continued throughout SPORANOX® therapy and for 2 months following the end of treatment. During post-marketing experience, cases of congenital abnormalities have been reported. (See ADVERSE REACTIONS: Post-marketing Experience.) Nursing Mothers Itraconazole is excreted in human milk; therefore, the expected benefits of SPORANOX® therapy for the mother should be weighed against the potential risk from exposure of itraconazole to the infant. The U.S. Public Health Service Centers for Disease Control and Prevention advises HIV-infected women not to breast-feed to avoid potential transmission of HIV to uninfected infants. Pediatric Use The efficacy and safety of SPORANOX® have not been established in pediatric patients. The long-term effects of itraconazole on bone growth in children are unknown. In three toxicology studies using rats, itraconazole induced bone defects at dosage levels as low as 20 mg/kg/day (2.5 times the MRHD). The induced defects included reduced bone plate activity, thinning of the zona compacta of the large bones, and increased bone fragility. At a dosage level of 80 mg/kg/day (10 times the MRHD) over 1 year or 160 mg/kg/day (20 times the MRHD) for 6 months, itraconazole induced small tooth pulp with hypocellular appearance in some rats. Geriatric Use Clinical studies of SPORANOX® Capsules did not include sufficient numbers of subjects aged 65 years and over to determine whether they respond differently from younger subjects. It is advised to use SPORANOX® Capsules in these patients only if it is determined that the potential benefit outweighs the potential risks. In general, it is recommended that the dose selection for an elderly patient should be taken into consideration, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Transient or permanent hearing loss has been reported in elderly patients receiving treatment with itraconazole. Several of these reports included concurrent administration of quinidine which is contraindicated (See BOXED WARNING: Drug Interactions, CONTRAINDICATIONS: Drug Interactions and DRUG INTERACTIONS). HIV-Infected Patients Because hypochlorhydria has been reported in HIV-infected individuals, the absorption of itraconazole in these patients may be decreased. Renal Impairment Limited data are available on the use of oral itraconazole in patients with renal impairment. The exposure of itraconazole may be lower in some patients with renal impairment. Caution should be exercised when itraconazole is administered in this patient population and dose adjustment may be needed. (See CLINICAL PHARMACOLOGY: Special Populations and DOSAGE AND ADMINISTRATION.) Hepatic Impairment Limited data are available on the use of oral itraconazole in patients with hepatic impairment. Caution should be exercised when this drug is administered in this patient population. It is recommended that patients with impaired hepatic function be carefully monitored when taking SPORANOX®. It is recommended that the prolonged elimination half-life of itraconazole observed in the single oral dose clinical trial with itraconazole capsules in cirrhotic patients be considered when deciding to initiate therapy with other medications metabolized by CYP3A4. In patients with elevated or abnormal liver enzymes or active liver disease, or who have experienced liver toxicity with other drugs, treatment with SPORANOX® is strongly discouraged unless there is a serious or life-threatening situation where the expected benefit exceeds the risk. It is recommended that liver function monitoring be done in patients with pre-existing hepatic function abnormalities or those who have experienced liver toxicity with other medications.
