What's The Definition Of The Medical Condition Testim?Clinical Pharmacology CLINICAL PHARMACOLOGY Mechanism Of Action Endogenous androgens, including testosterone and dihydrotestosterone (DHT), are responsible for the normal growth and development of the male sex organs and for maintenance of secondary sex characteristics.
These effects include the growth and maturation of prostate, seminal vesicles, penis and scrotum; the development of male hair distribution, such as facial, pubic, chest and axillary hair; laryngeal enlargement; vocal cord thickening; and alterations in body musculature and fat distribution.
Testosterone and DHT are necessary for the normal development of secondary sex characteristics.
Male hypogonadism, a clinical syndrome resulting from insufficient secretion of testosterone, has two main etiologies.
Primary hypogonadism is caused by defects of the gonads, such as Klinefelter's syndrome or Leydig cell aplasia, while secondary hypogonadism (hypogonadotropic hypogonadism) is the failure of the hypothalamus (or pituitary) to produce sufficient gonadotropins (FSH, LH).
Pharmacodynamics No specific pharmacodynamic studies were conducted using Testim.
Pharmacokinetics Absorption Testim® (testosterone gel) delivers physiologic amounts of testosterone, producing circulating testosterone concentrations that approximate normal concentrations (e.g., 300 - 1000 ng/dL) seen in healthy men.
The skin serves as a reservoir for the sustained release of testosterone into the systemic circulation.
Approximately 10% of the testosterone applied on the skin surface is absorbed into the systemic circulation during a 24-hour period.
Single Dose In single dose studies, when either Testim 50 mg or 100 mg was administered, absorption of testosterone into the blood continued for the entire 24 hour dosing period.
Also, mean peak and average serum concentrations within the normal range were achieved within 24 hours.
Multiple Dose With single daily applications of Testim 50 mg and 100 mg, follow-up measurements at 30 and 90 days after starting treatment have confirmed that serum testosterone and DHT concentrations are generally maintained within the normal range.
Figure 1 summarizes the 24-hour pharmacokinetic profile of testosterone for patients maintained on Testim 50 mg or Testim 100 mg for 30 days.
Figure 1 : Mean Steady-State Serum Testosterone (±SD) (ng/dL) Concentrations on Day 30 in Patients Applying Testim Once Daily The average daily testosterone concentration produced by Testim 100 mg at Day 30 was 612 (± 286) ng/dL and by Testim 50 mg at Day 30 was 365 (± 187) ng/dL.
Distribution Circulating testosterone is primarily bound in the serum to sex hormone-binding globulin (SHBG) and albumin.
Approximately 40% of testosterone in plasma is bound to SHBG, 2% remains unbound (free) and the rest is loosely bound to albumin and other proteins.
Metabolism Testosterone is metabolized to various 17-keto steroids through two different pathways.
The major active metabolites of testosterone are estradiol and DHT.
The average daily DHT concentration produced by Testim 100 mg at Day 30 was 555 (± 293) pg/mL and by Testim 50 mg at Day 30 was 346 (± 212) pg/mL.
Figure 2 summarizes the 24-hour pharmacokinetic profile of DHT for patients maintained on Testim 50 mg or Testim 100 mg for 30 days.
Figure 2 : Mean Steady-State Serum Dihydrotestosterone (±SD) (pg/mL) Concentrations on Day 30 in Patients Applying Testim Once Daily Excretion There is considerable variation in the half-life of testosterone concentration as reported in the literature, ranging from 10 to 100 minutes.
About 90% of a dose of testosterone given intramuscularly is excreted in the urine as glucuronic acid and sulfuric acid conjugates of testosterone and its metabolites.
About 6% of a dose is excreted in the feces, mostly in the unconjugated form.
Inactivation of testosterone occurs primarily in the liver.
Potential For Testosterone Transfer From Male Patients To Female Partners The potential for dermal testosterone transfer following Testim use was evaluated in two clinical trials with males dosed with Testim and their untreated female partners.
In the first trial, 30 couples were evenly randomized to five groups.
In the first four groups, 100 mg of Testim was applied to the male abdomen and the couples were then asked to rub abdomen-to-abdomen for 15 minutes at 1 hour, 4 hours, 8 hours or 12 hours after dose application, respectively.
In these couples, serum testosterone concentrations in female partners increased from baseline by at least 6 times and potential for transfer was seen at all timepoints.
When 6 males used a shirt to cover the abdomen at 15 minutes post-application and partners again rubbed abdomens for 15 minutes at the 1 hour timepoint, serum testosterone concentrations in female partners increased from baseline by approximately 3 times.
In the second trial, 24 couples were evenly randomized to four groups.
Testim 100 mg was applied to the male upper arms and shoulders.
In one group, 15 minutes of direct skin-to-skin rubbing began at 4 hours after application.
In these six women, all of whom showered immediately after the rubbing activity, mean maximum serum testosterone concentrations increased from baseline by approximately 4 times.
When males wore a long-sleeved T-shirt and rubbing was started at 1 and at 4 hours after application, the transfer of testosterone from male to female partners was prevented.
Effect Of Showering The effect of showering (with mild soap) at 1, 2 and 6 hours post application of Testim 100 mg was evaluated in a clinical trial in 12 men.
The study demonstrated that the overall effect of washing was to decrease testosterone concentrations; however, when washing occurred two or more hours post drug application, serum testosterone concentrations remained within the normal range.
Clinical Studies Clinical Trials In Adult Hypogonadal Males Testim® was evaluated in a randomized multicenter, multi-dose, active and placebo controlled 90-day study in 406 adult males with morning testosterone concentrations ≤ 300 ng/dL.
The study was double-blind for the doses of Testim and placebo, but open label for the non-scrotal testosterone transdermal system.
During the first 60 days, patients were evenly randomized to Testim 50 mg, Testim 100 mg, placebo gel, or testosterone transdermal system.
At Day 60, patients receiving Testim were maintained at the same dose, or were titrated up or down within their treatment group, based on 24-hour averaged serum testosterone concentration obtained on Day 30.
Of 192 hypogonadal men who were appropriately titrated with Testim and who had sufficient data for analysis, 74% achieved an average serum testosterone concentration within the normal range (300 to 1,000 ng/dL) on treatment Day 90.
Table 2 summarizes the mean testosterone concentrations on Day 30 for patients receiving Testim 50 mg or 100 mg.

Drug Description Find Lowest Prices on TESTIM® (testosterone) Gel WARNING SECONDARY EXPOSURE TO TESTOSTERONE Virilization has been reported in children who were secondarily exposed to testosterone gel [see WARNINGS AND PRECAUTIONS and ADVERSE REACTIONS].
Children should avoid contact with unwashed or unclothed application sites in men using testosterone gel [see DOSAGE AND ADMINISTRATION and WARNINGS AND PRECAUTIONS] Healthcare providers should advise patients to strictly adhere to recommended instructions for use [see DOSAGE AND ADMINISTRATION, WARNINGS AND PRECAUTIONS and PATIENT INFORMATION].
DESCRIPTION Testim® (testosterone gel) is a clear to translucent hydroalcoholic topical gel containing testosterone, an androgen.
Testim provides continuous transdermal delivery of testosterone for 24 hours, following a single application to intact, clean, dry skin of the shoulders and/or upper arms.
One 5-g or two 5-g tubes of Testim contains 50 mg or 100 mg of testosterone, respectively, to be applied daily to the skin's surface.
Approximately 10% of the applied testosterone dose is absorbed across skin of average permeability during a 24-hour period.
The active pharmacological ingredient in Testim is testosterone.
Testosterone USP is a white to practically white crystalline powder chemically described as 17-β hydroxyandrost-4-en-3-one.
The structural formula is shown in the following figure: Inactive ingredients in Testim are purified water, pentadecalactone, carbopol, acrylates, propylene glycol, glycerin, polyethylene glycol, ethanol (74%), and tromethamine.
Indications & Dosage INDICATIONS Testim® is indicated for testosterone replacement therapy in adult males for conditions associated with a deficiency or absence of endogenous testosterone: Primary hypogonadism (congenital or acquired): testicular failure due to cryptorchidism, bilateral torsion, orchitis, vanishing testis syndrome, orchiectomy, Klinefelter's syndrome, chemotherapy, or toxic damage from alcohol or heavy metals.
These men usually have low serum testosterone concentrations and gonadotropins (follicle-stimulating hormone [FSH], luteinizing hormone [LH]) above the normal range.
Hypogonadotropic hypogonadism (congenital or acquired): gonadotropin or luteinizing hormone-releasing hormone (LHRH) deficiency or pituitary-hypothalamic injury from tumors, trauma, or radiation.
These men have low testosterone serum concentrations but have gonadotropins in the normal or low range.
Limitations Of Use Safety and efficacy of Testim in men with “age-related hypogonadism” (also referred to as “late-onset hypogonadism”) have not been established.
Safety and efficacy of Testim in males less than 18 years old have not been established [see Use in Specific Populations].
Topical testosterone products may have different doses, strengths, or application instructions that may result in different systemic exposure [see DOSAGE AND ADMINISTRATION and CLINICAL PHARMACOLOGY].
DOSAGE AND ADMINISTRATION Prior to initiating, Testim confirm the diagnosis of hypogonadism by ensuring that serum testosterone concentrations have been measured in the morning on at least two separate days and that these serum testosterone concentrations are below the normal range.
Dosing And Dose Adjustment The recommended starting dose of Testim® is 50 mg of testosterone (one tube) applied once daily (preferably in the morning) to clean, dry intact skin of the shoulders and/or upper arms.
Dose Adjustment To ensure proper dosing, serum testosterone concentrations should be measured.
Morning, pre-dose serum testosterone concentrations should be measured approximately 14 days after initiation of therapy to ensure proper serum testosterone concentrations are achieved.
If the serum testosterone concentration is below the normal range (300 ng/dL to 1,000 ng/dL), the daily Testim dose may be increased from 50 mg testosterone (one tube) to 100 mg testosterone (two tubes) once daily.
The maximum recommended dose of Testim is 100 mg once daily.
The application site and dose of Testim are not interchangeable with other topical testosterone products.
Administration Instructions Upon opening the tube the entire contents should be squeezed into the palm of the hand and immediately applied to the shoulders and/or upper arms (area of application should be limited to the area that will be covered by the patient's short sleeve T-shirt (see figure below).
Do not apply Testim to the genitals or to the abdomen.
Application sites should be allowed to dry for a few minutes prior to dressing.
Hands should be washed thoroughly with soap and water after Testim has been applied.
Avoid fire, flame or smoking during the application of Testim until the Testim has dried [see WARNINGS AND PRECAUTIONS].
In order to prevent transfer to another person, wear clothing to cover the application sites.
If direct skin-to-skin contact with another person is anticipated, the application sites must be washed thoroughly with soap and water [see WARNINGS AND PRECAUTIONS and CLINICAL PHARMACOLOGY].
The patient should avoid swimming or showering or washing the administration site for a minimum of 2 hours after application [see CLINICAL PHARMACOLOGY].
Strict adherence to the following precautions is advised in order to minimize the potential for secondary exposure to testosterone from Testim-treated skin: Children and women should avoid contact with unwashed or unclothed application site(s) of men using Testim.
Testim should only be applied to the upper arms and shoulders.
The area of application should be limited to the area that will be covered by a short sleeve T-shirt.
Patients should wash their hands with soap and water immediately after applying Testim.
Patients should cover the application site(s) with clothing (e.g., a T-shirt) after the gel has dried.
Prior to situations in which direct skin-to-skin contact is anticipated, patients should wash the application site(s) thoroughly with soap and water to remove any testosterone residue.
In the event that unwashed or unclothed skin to which Testim has been applied comes in direct contact with the skin of another person, the general area of contact on the other person should be washed with soap and water as soon as possible.

Overdosage & Contraindications Side Effects & Drug Interactions Warnings & Precautions WARNINGS Included as part of the PRECAUTIONS section.
PRECAUTIONS Worsening Of Benign Prostatic Hyperplasia (BPH) And Potential Risk Of Prostate Cancer Patients with BPH treated with androgens are at an increased risk for worsening of signs and symptoms of BPH.
Monitor patients with BPH for worsening signs and symptoms.
Patients treated with androgens may be at increased risk for prostate cancer.
Evaluate patients for prostate cancer prior to initiating and during treatment with androgens [see CONTRAINDICATIONS].
Potential For Secondary Exposure To Testosterone Cases of secondary exposure resulting in virilization of children have been reported in postmarketing surveillance.
Signs and symptoms have included enlargement of the penis or clitoris, development of pubic hair, increased erections and libido, aggressive behavior, and advanced bone age.
In most cases, these signs and symptoms regressed with removal of the exposure to testosterone gel.
In a few cases, however, enlarged genitalia did not fully return to age-appropriate normal size, and bone age remained modestly greater than chronological age.
The risk of transfer was increased in some of these cases by not adhering to precautions for the appropriate use of the topical testosterone product.
Children and women should avoid contact with unwashed or unclothed application sites in men using Testim [see DOSAGE AND ADMINISTRATION, Use in Specific Populations and CLINICAL PHARMACOLOGY].
Inappropriate changes in genital size or development of pubic hair or libido in children, or changes in body hair distribution, significant increase in acne, or other signs of virilization in adult women should be brought to the attention of a physician and the possibility of secondary exposure to testosterone gel should also be brought to the attention of a physician.
Testosterone gel should be promptly discontinued until the cause of virilization has been identified.
Polycythemia Increases in hematocrit, reflective of increases in red blood cell mass, may require lowering or discontinuation of testosterone.
Check hematocrit prior to initiating treatment.
It would also be appropriate to re-evaluate the hematocrit 3 to 6 months after starting treatment, and then annually.
If hematocrit becomes elevated, stop therapy until hematocrit decreases to an acceptable concentration.
An increase in red blood cell mass may increase the risk of thromboembolic events.
Venous Thromboembolism There have been postmarketing reports of venous thromboembolic events, including deep vein thrombosis (DVT) and pulmonary embolism (PE), in patients using testosterone products, such as Testim.
Evaluate patients who report symptoms of pain, edema, warmth and erythema in the lower extremity for DVT and those who present with acute shortness of breath for PE.
If a venous thromboembolic event is suspected, discontinue treatment with Testim and initiate appropriate workup and management [see ADVERSE REACTIONS].
Cardiovascular Risk Long term clinical safety trials have not been conducted to assess the cardiovascular outcomes of testosterone replacement therapy in men.
To date, epidemiologic studies and randomized controlled trials have been inconclusive for determining the risk of major adverse cardiovascular events (MACE), such as non-fatal myocardial infarction, non-fatal stroke, and cardiovascular death, with the use of testosterone compared to non-use.
Some studies, but not all, have reported an increased risk of MACE in association with use of testosterone replacement therapy in men.
Patients should be informed of this possible risk when deciding whether to use or to continue to use Testim.
Use in Women Due to lack of controlled evaluations in women and potential virilizing effects, Testim is not indicated for use in women [see CONTRAINDICATIONS and Use in Specific Populations].
Potential For Adverse Effects On Spermatogenesis With large doses of exogenous androgens, including Testim, spermatogenesis may be suppressed through feedback inhibition of pituitary follicle-stimulating hormone (FSH) which could possibly lead to adverse effects on semen parameters including sperm count.
Hepatic Adverse Effects Prolonged use of high doses of orally active 17-alpha-alkyl androgens (e.g., methyltestosterone) has been associated with serious hepatic adverse effects (peliosis hepatis, hepatic neoplasms, cholestatic hepatitis, and jaundice).
Peliosis hepatis can be a life-threatening or fatal complication.
Long-term therapy with intramuscular testosterone enanthate, which elevates blood levels for prolonged periods, has produced multiple hepatic adenomas.
Testim is not known to cause these adverse effects.
Nonetheless, patients should be instructed to report any signs or symptoms of hepatic dysfunction (e.g., jaundice).
If these occur, promptly discontinue Testim while the cause is evaluated.
Edema Androgens, including Testim, may promote retention of sodium and water.
Edema, with or without congestive heart failure, may be a serious complication in patients with preexisting cardiac, renal, or hepatic disease.
In addition to discontinuation of the drug, diuretic therapy may be required.
Gynecomastia Gynecomastia occasionally develops and occasionally persists in patients being treated for hypogonadism [see ADVERSE REACTIONS].
Sleep Apnea The treatment of hypogonadal men with testosterone may potentiate sleep apnea in some patients, especially those with risk factors such as obesity or chronic lung diseases.
Lipids Changes in the serum lipid profile may occur.
Monitor the lipid profile periodically, particularly after starting testosterone therapy and after dose increases.
Hypercalcemia Androgens, including Testim, should be used with caution in cancer patients at risk of hypercalcemia (and associated hypercalciuria).
Regular monitoring of serum calcium concentrations is recommended in these patients.
Decreased Thyroxine-binding Globulin Androgens, including Testim, may decrease concentrations of thyroxine-binding globulins, resulting in decreased total T4 serum concentrations and increased resin uptake of T3 and T4.
Free thyroid hormone concentrations remain unchanged, however, and there is no clinical evidence of thyroid dysfunction.
Flammability Alcohol-based products, including Testim, are flammable; therefore, patients should be advised to avoid fire, flame or smoking until the Testim has dried.
Patient Counseling Information See FDA-approved patient labeling (Medication Guide).
Advise patients of the following: Men With Known Or Suspected Carcinoma Of The Breast Or Prostate Men with known or suspected prostate or breast cancer should not use Testim® [see CONTRAINDICATIONS and WARNINGS AND PRECAUTIONS].
Potential For Secondary Exposure To Testosterone And Steps To Prevent Secondary Exposure Secondary exposure to testosterone in children and women can occur with the use of testosterone gel in men.
Cases of secondary exposure to testosterone have been reported in children.
Physicians should advise patients of the reported signs and symptoms of secondary exposure which may include the following: In children; unexpected sexual development including inappropriate enlargement of the penis or clitoris, premature development of pubic hair, increased erections, and aggressive behavior In women; changes in hair distribution, increase in acne, or other signs of testosterone effects The possibility of secondary exposure to testosterone gel should be brought to the attention of a healthcare provider Testim should be promptly discontinued until the cause of virilization is identified Strict adherence to the following precautions is advised to minimize the potential for secondary exposure to testosterone from testosterone gel in men [see Medication Guide]: Children and women should avoid contact with unwashed or unclothed application site(s) of men using testosterone gel Patients using Testim should apply the product as directed and strictly adhere to the following: Wash hands with soap and water immediately after application Cover the application site(s) with clothing after the gel has dried Wash the application site(s) thoroughly with soap and water prior to any situation where skin-to-skin contact of the application site with another person is anticipated In the event that unwashed or unclothed skin to which Testim has been applied comes in contact with the skin of another person, the general area of contact on the other person should be washed with soap and water as soon as possible [see DOSAGE AND ADMINISTRATION, WARNINGS AND PRECAUTIONS and CLINICAL PHARMACOLOGY].
Potential Adverse Reactions With Androgens Patients should be informed that treatment with androgens may lead to adverse reactions which include: Changes in urinary habits, such as increased urination at night, trouble starting the urine stream, passing urine many times during the day, having an urge to go the bathroom right away, having a urine accident, or being unable to pass urine or weak urine flow Breathing disturbances, including those associated with sleep or excessive daytime sleepiness.
Too frequent or persistent erections of the penis Nausea, vomiting, changes in skin color, or ankle swelling Patients Should Be Advised Of The Following Instructions For Use Read the Medication Guide before starting Testim therapy and reread it each time the prescription is renewed.
Testim should be applied and used appropriately to maximize the benefits and to minimize the risk of secondary exposure in children and women Keep Testim out of the reach of children.
The package is not child resistant.
Testim is an alcohol-based product and is flammable; therefore avoid fire, flame or smoking until the gel has dried It is important to adhere to all recommended monitoring Report any changes in their state of health, such as changes in urinary habits, breathing, sleep, and mood Testim is prescribed to meet the patient’s specific needs; therefore, the patient should never share Testim with anyone.
Testim should be applied once daily at approximately the same time each day to clean dry skin of the shoulders and/or upper arms.
Testim should not be applied to the scrotum, penis, or abdomen.
Wait 2 hours before swimming or washing following application of Testim.
This will ensure that the greatest amount of Testim is absorbed into their system.
Nonclinical Toxicology Carcinogenesis, Mutagenesis, Impairment Of Fertility Carcinogenicity Testosterone has been tested by subcutaneous injection and implantation in mice and rats.
In mice, the implant induced cervical-uterine tumors, which metastasized in some cases.
There is suggestive evidence that injection of testosterone into some strains of female mice increases their susceptibility to hepatoma.
Testosterone is also known to increase the number of tumors and decrease the degree of differentiation of chemically induced carcinomas of the liver in rats.
Mutagenesis Testosterone was negative in the in vitro Ames and in the in vivo mouse micronucleus assays.
Impairment Of Fertility The administration of exogenous testosterone has been reported to suppress spermatogenesis in the rat, dog and non-human primates, which was reversible on cessation of the treatment.
Use In Specific Populations Pregnancy Pregnancy Category X [see CONTRAINDICATIONS]: Testim® is contraindicated in pregnant women or in women who may become pregnant.
Testosterone is teratogenic and may cause fetal harm.
Exposure of a fetus to androgens, such as testosterone, may result in varying degrees of virilization.
If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be made aware of the potential hazard to the fetus.
Nursing Mothers Although it is not known how much testosterone transfers into human milk, Testim is contraindicated in nursing women because of the potential for serious adverse reactions in nursing infants [see CONTRAINDICATIONS].
Pediatric Use The safety and effectiveness of Testim in pediatric patients less than 18 years old have not been established.
Improper use may result in acceleration of bone age and premature closure of epiphyses.
Geriatric Use There is insufficient long-term safety data in geriatric patients to assess the potentially increased risks of cardiovascular disease and prostate cancer [see WARNINGS AND PRECAUTIONS].
Renal Impairment No studies were conducted in patients with renal impairment.
Hepatic Impairment No studies were conducted in patients with hepatic impairment.
