INDICATIONS

Testosterone Replacement Therapy

AndroGel, an androgen, is indicated for replacement therapy in adult males for conditions associated with a deficiency or absence of endogenous testosterone:

DOSAGE AND ADMINISTRATION

General Dosing

The recommended starting dose of AndroGel is 5 g once daily (preferably in the morning) to clean, dry, intact skin of the shoulders and upper arms and/or abdomen (area of application should be limited to the area that will be covered by the patient's short sleeve t-shirt). AndroGel must not be applied to the genitals. AndroGel is supplied as either a pump or in individual packets. After applying the gel, the application site should be allowed to dry for a few minutes prior to dressing. Avoid fire, flames or smoking until the gel has dried since alcohol based products, including AndroGel, are flammable. Hands should be washed with soap and water after AndroGel has been applied, [see WARNINGS AND PRECAUTIONS].

Administration

Multi-Dose Pump

Patients should be instructed to prime the pump before using it for the first time by fully depressing the pump mechanism (actuation) 3 times and discard this portion of the product to assure precise dose delivery. After the priming procedure, patients should completely depress the pump one time (actuation) for every 1.25 g (AndroGel Pump) of product required to achieve the daily prescribed dosage. The product may be delivered directly into the palm of the hand and then applied to the desired application sites, either one pump actuation at a time or upon completion of all pump actuations required for the daily dose. Alternatively, the product can be applied directly to the application sites. Application directly to the sites may prevent loss of product that may occur during transfer from the palm of the hand onto the application sites. Table 1 has specific dosing guidelines for adult males when the 75 g AndroGel Pump is used.

Table 1: Specific Dosing Guidelines for Using the Adult Multi-Dose Pump

Prescribed Daily Dose Number of Pump Actuations in 75 g Pump
5g 4 (once daily)
7.5 g 6 (once daily)
10 g 8 (once daily)

Packets

The entire contents should be squeezed into the palm of the hand and immediately applied to the application sites. Alternately, patients may squeeze a portion of the gel from the packet into the palm of the hand and apply to application sites. Repeat until entire contents have been applied.

Dose Adjustment and Patient Assessments

  • To ensure proper dosing, serum testosterone levels should be measured at intervals and replaced to serum testosterone levels in the normal range. If the serum testosterone concentration is below the normal range, the daily AndroGel dose may be increased from 5 g to 7.5 g and from 7.5 g to 10 g for adult males as instructed by the physician. If the serum testosterone concentration exceeds the normal range, the daily AndroGel dose may be decreased. If the serum testosterone concentration consistently exceeds the normal range at a daily dose of 5 g, AndroGel therapy should be discontinued.

The following is general advice for treating and monitoring adult patients on AndroGel. No specific recommendations can be made.

  • Prescribers should be aware that testosterone is contraindicated in men with known or suspected prostate cancer. Therefore, evaluation for prostate cancer prior to initiation of AndroGel therapy is appropriate [see CONTRAINDICATIONS].
  • Based on results from controlled studies, serum PSA may rise when taking AndroGel. Therefore, periodic assessment of serum PSA is recommended in patients taking AndroGel [see ADVERSE REACTIONS].
  • Based on results from controlled studies, worsening of BPH may occur in patients taking AndroGel [see ADVERSE REACTIONS]. Therefore, periodic assessments for signs and symptoms of BPH are recommended in patients taking AndroGel.
  • Hematocrit, serum lipid profile, and liver function test should be monitored in patients taking AndroGel [see WARNINGS AND PRECAUTIONS].

SIDE EFFECTS

Clinical Trial 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.

Clinical Trials in Hypogonadal Men

Table 2 shows the incidence of all adverse events judged by the investigator to be at least possibly related to treatment with AndroGel and reported by > 1% of patients in a 180 Day, Phase 3 study.

*Lab test abnormal occurred in nine patients with one or more of the following events reported: elevated hemoglobin or hematocrit, hyperlipidemia, elevated triglycerides, hypokalemia, decreased HDL, elevated glucose, elevated creatinine, elevated total bilirubin.
**Prostate disorders included five patients with enlarged prostate, one with BPH, and one with elevated PSA results.
***Testis disorders were reported in two patients: one with left varicocele and one with slight sensitivity of left testis.

Other less common adverse reactions, reported in fewer than 1% of patients included: amnesia, anxiety, discolored hair, dizziness, dry skin, hirsutism, hostility, impaired urination, paresthesia, penis disorder, peripheral edema, sweating, and vasodilation.

In this 180 day clinical trial, skin reactions at the site of application were reported with AndroGel, but none was severe enough to require treatment or discontinuation of drug.

Six patients (4%) in this trial had adverse events that led to discontinuation of AndroGel. These events included: cerebral hemorrhage, convulsion (neither of which were considered related to AndroGel administration), depression, sadness, memory loss, elevated prostate specific antigen, and hypertension. No AndroGel patient discontinued due to skin reactions.

In a separate uncontrolled pharmacokinetic study of 10 patients, two had adverse events associated with AndroGel; these were asthenia and depression in one patient and increased libido and hyperkinesia in the other.

In a 3 year, flexible dose, extension study, the incidence of all adverse events judged by the investigator to be at least possibly related to treatment with AndroGel and reported by > 1% of patients is shown in Table 3.

**Testis disorders included three patients. There were two with a non-palpable testis and one with slight right testicular tenderness.

Two patients reported serious adverse events considered possibly related to treatment: deep vein thrombosis (DVT) and prostate disorder requiring a transurethral resection of the prostate (TURP).

Discontinuation for adverse events in this study included: two patients with application site reactions, one with kidney failure, and five with prostate disorders (including increase in serum PSA in 4 patients, and increase in PSA with prostate enlargement in a fifth patient).

Increases in Serum PSA Observed in Clinical Trials of Hypogonadal Men

During the initial 6-month study, the mean change in PSA values had a statistically significant increase of 0.26 ng/mL. Serum PSA was measured every 6 months thereafter in the 162 hypogonadal men on AndroGel in the 3-year extension study. There was no additional statistically significant increase observed in mean PSA from 6 months through 36 months. However, there were increases in serum PSA observed in approximately 18% of individual patients. The overall mean change from baseline in serum PSA values for the entire group from month 6 to 36 was 0.11 ng/mL.

Twenty-nine patients (18%) met the per-protocol criterion for increase in serum PSA, defined as > 2X the baseline or any single serum PSA > 6 ng/mL. Most of these (25/29) met this criterion by at least doubling of their PSA from baseline. In most cases where PSA at least doubled (22/25), the maximum serum PSA value was still < 2 ng/mL. The first occurrence of a pre-specified, post-baseline increase in serum PSA was seen at or prior to Month 12 in most of the patients who met this criterion (23 of 29; 79%).

Four patients met this criterion by having a serum PSA > 6 ng/mL and in these, maximum serum PSA values were 6.2 ng/mL, 6.6 ng/mL, 6.7 ng/mL, and 10.7 ng/mL. In two of these patients, prostate cancer was detected on biopsy. The first patient's PSA levels were 4.7 ng/mL and 6.2 ng/mL at baseline and at Month 6/Final, respectively. The second patient's PSA levels were 4.2 ng/mL, 5.2 ng/mL, 5.8 ng/mL, and 6.6 ng/mL at baseline, Month 6, Month 12, and Final, respectively.

Postmarketing Experience

The following adverse reactions have been identified during post approval use of AndroGel. Because the 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.

Secondary Exposure to Testosterone in Children

Cases of secondary exposure to testosterone resulting in virilization of children have been reported in postmarket surveillance. Signs and symptoms of these reported cases have included enlargement of the clitoris (with surgical intervention) or the penis, development of pubic hair, increased erections and libido, aggressive behavior, and advanced bone age. In most cases with a reported outcome, these signs and symptoms were reported to have regressed with removal of the testosterone gel exposure. 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. In some of the cases, direct contact with the sites of application on the skin of men using testosterone gel was reported. In at least one reported case, the reporter considered the possibility of secondary exposure from items such as the testosterone gel user's shirts and/or other fabric, such as towels and sheets [see WARNINGS AND PRECAUTIONS].

DRUG INTERACTIONS

Insulin

Changes in insulin sensitivity or glycemic control may occur in patients treated with androgens. In diabetic patients, the metabolic effects of androgens may decrease blood glucose and, therefore, insulin requirements.

Corticostcroids

The concurrent use of testosterone with ACTH or corticosteroids may result in increased fluid retention and should be monitored cautiously, particularly in patients with cardiac, renal or hepatic disease.

Oral Anticoagulants

Changes in anticoagulant activity may be seen with androgens. More frequent monitoring of INR and prothrombin time are recommended in patients taking anticoagulants, especially at the initiation and termination of androgen therapy.

Drug Abuse And Dependence

Controlled Substance

AndroGel contains testosterone, a Schedule III controlled substance as defined by the Anabolic Steroids Control Act.

Oral ingestion of AndroGel will not result in clinically significant serum testosterone concentrations due to extensive first-pass metabolism.

Last reviewed on RxList: 12/12/2011

WARNINGS

Included as part of the PRECAUTIONS section.

PRECAUTIONS

Benign Prostatic Hyperplasia 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.
  • Patients treated with androgens may be at increased risk for prostate cancer. Evaluation of the patient for prostate cancer prior to initiating and during treatment with androgens is appropriate.
  • Increases in serum PSA from baseline values were seen in approximately 18% of individuals in an open label study of 162 hypogonadal men treated with AndroGel for up to 42 months. Most of these increases were seen within the first year of therapy [see CONTRAINDICATIONS, ADVERSE REACTIONS, and Nonclinical Toxicology].

Potential for Secondary Exposure to Testosterone

Secondary exposure to testosterone in children and women can occur with testosterone gel use in men [see Clinical Studies]. 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 testosterone gel.

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.

Testosterone may cause fetal harm in a pregnant woman due to virilization of a female fetus [see Use In Specific Populations].

Strict adherence to the following precautions is advised in order to minimize the potential for secondary exposure to testosterone from AndroGel-treated skin:

  • Children and women should avoid contact with unwashed or unclothed application site(s) of men using testosterone gel.
  • AndroGel should only be applied to the shoulders, upper arms, and/or abdomen (area of application should be limited to the area that will be covered by the patient's short sleeve t-shirt).
  • Patients should wash their hands immediately with soap and water after applying AndroGel.
  • Patients should cover the application site(s) with clothing (e.g., a shirt) after the gel has dried.
  • Prior to any situation in which skin-to-skin contact with the application site 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 AndroGel 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. Studies show that residual testosterone is removed from the skin surface by washing with soap and water.

Use in Women

Due to lack of controlled evaluations in women and potential virilizing effects, AndroGel is not indicated for use in women [see Use In Specific Populations].

Potential for Adverse Effects on Spermatogenesis

At large doses of exogenous androgens, 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 has produced multiple hepatic adenomas. AndroGel is not known to produce these adverse effects.

There are rare reports of hepatocellular carcinoma in patients receiving long-term oral therapy with androgens in high doses. Withdrawal of the drugs did not lead to regression of the tumors in all cases.

Edema

Drugs in the androgen class 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 [see ADVERSE REACTIONS].

Gynecomastia

Gynecomastia may develop and may persist in patients being treated with androgens, including AndroGel, for hypogonadism.

Sleep Apnea

The treatment of hypogonadal men with testosterone products may potentiate sleep apnea in some patients, especially those with risk factors such as obesity or chronic lung diseases [see ADVERSE REACTIONS].

Laboratory Tests

  • Increases in hematocrit, reflective of increases in red blood cell mass, may require lowering or discontinuation of testosterone. Increase in red blood cell mass may increase the risk for a thromboembolic event.
  • Changes in serum lipid profile may require dose adjustment or discontinuation of testosterone therapy.
  • Androgens may decrease levels of thyroxin-binding globulin, resulting in decreased total T4 serum levels and increased resin uptake of T3 and T4. Free thyroid hormone levels remain unchanged, however, and there is no clinical evidence of thyroid dysfunction.
  • Androgens 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.

Flammable Until Dry

  • Alcohol Based Products including AndroGel are flammable; therefore avoid fire, flame or smoking until the gel has dried.

Patient Counseling Information

See FDA-Approved Medication Guide

Men with known or suspected prostate or breast cancer should not use AndroGel

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 with signs and symptoms including enlargement of the penis or clitoris, premature development of pubic hair, increased erections, and aggressive behavior.

  • 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
  • Testosterone gel 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 FDA-Approved Medication Guide]:

  • Children and women should avoid contact with unwashed or unclothed application site(s) of men using testosterone gel
  • To minimize the potential for transfer to others, patients using AndroGel should apply the product as directed and strictly adhere to the following:
  • Wash hands with soap and water 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 testosterone gel 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.

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 your urine stream, passing urine many times during the day, having an urge that you have to go to the bathroom right away, having a urine accident, being unable to pass urine and 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

  • To read the Medication Guide before starting AndroGel therapy and to reread it each time the prescription is renewed
  • Of the appropriate application and use of AndroGel to maximize the benefits and to minimize the risk of secondary exposure in children and women
  • To keep AndroGel out of the reach of children
  • That AndroGel is an alcohol based product and is flammable; therefore avoid fire, flame or smoking until the gel has dried
  • Of the importance of adhering to all recommended monitoring
  • To report any changes in their state of health, such as changes in urinary habits, breathing, sleep, and mood
  • To wait 5 hours before showering or swimming. This will ensure that the greatest amount of AndroGel is absorbed into their system.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility

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.

Use In Specific Populations

Pregnancy

Pregnancy Category X: AndroGel is contraindicated during pregnancy or in women who may become pregnant. It is teratogenic and may cause fetal harm [see CONTRAINDICATIONS]. Exposure of a female fetus to androgens 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 apprised of the potential hazard to a fetus.

Nursing Mothers

Although it is not known how much testosterone transfers into human milk, AndroGel is contraindicated in nursing women because of the potential for serious adverse reactions in nursing infants [see CONTRAINDICATIONS].

Testosterone and other androgens may adversely affect lactation.

Pediatric Use

Safety and efficacy of AndroGel in males < 18 years old has not been established. Improper use may result in acceleration of bone age and premature closure of epiphyses.

Geriatric Use

There have not been sufficient numbers of geriatric patients involved in controlled clinical studies utilizing AndroGel to determine whether efficacy in those over 65 years of age differs from younger subjects. Additionally, there is insufficient long-term safety data in geriatric patients to assess the potential risks of cardiovascular disease and prostate cancer.

Renal or Hepatic Impairment

No formal studies were conducted involving patients with renal or hepatic insufficiencies.

This monograph has been modified to include the generic and brand name in many instances.

OVERDOSE

There is one report of acute overdosage with use of an approved injectable testosterone product: this subject had serum testosterone levels of up to 11,400 ng/dL with a cerebrovascular accident. Treatment of overdosage would consist of discontinuation of AndroGel together with appropriate symptomatic and supportive care.

CONTRAINDICATIONS

AndroGel should not be used in any of the following patients:

Men with carcinoma of the breast or known or suspected carcinoma of the prostate [see WARNINGS AND PRECAUTIONS, ADVERSE REACTIONS, and Nonclinical Toxicology].

Women who are or may become pregnant, or who are breastfeeding. AndroGel can cause fetal harm when administered to a pregnant woman. AndroGel may cause serious adverse reactions in nursing infants. Exposure of a female fetus or nursing infant to androgens may result in varying degrees of virilization. Pregnant women or those who may become pregnant need to be aware of the potential for transfer of testosterone from men treated with AndroGel [see WARNINGS AND PRECAUTIONS and Use In Specific Populations].

Men with known hypersensitivity to any of its ingredients, including alcohol and soy products.

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 chord thickening, alterations in body musculature and fat distribution. Testosterone and DHT are necessary for the normal development of secondary sex characteristics. Male hypogonadism results from insufficient secretion of testosterone and is characterized by low serum testosterone concentrations. Signs/symptoms associated with male hypogonadism include erectile dysfunction and decreased sexual desire, fatigue and loss of energy, mood depression, regression of secondary sexual characteristics and osteoporosis.

Male hypogonadism has two main etiologies. Primary hypogonadism is caused by defects of the gonads, such as Klinefelter's Syndrome or Leydig cell aplasia, whereas secondary hypogonadism is the failure of the hypothalamus (or pituitary) to produce sufficient gonadotropins (FSH, LH).

Pharmacokinetics

Adult Males

Absorption

AndroGel delivers physiologic amounts of testosterone, producing circulating testosterone concentrations that approximate normal levels (298 - 1043 ng/dL) seen in healthy men. AndroGel provides continuous transdermal delivery of testosterone for 24 hours following a single application to intact, clean, dry skin of the shoulders, upper arms and/or abdomen.

AndroGel is a hydroalcoholic formulation that dries quickly when applied to the skin surface. The skin serves as a reservoir for the sustained release of testosterone into the systemic circulation. Approximately 10% of the testosterone dose applied on the skin surface from AndroGel is absorbed into systemic circulation. Therefore, 5 g and 10 g of AndroGel systemically deliver approximately 5 mg and 10 mg of testosterone, respectively. In a study with 10 g of AndroGel, all patients showed an increase in serum testosterone within 30 minutes, and eight of nine patients had a serum testosterone concentration within normal range by 4 hours after the initial application. Absorption of testosterone into the blood continues for the entire 24-hour dosing interval. Serum concentrations approximate the steady-state level by the end of the first 24 hours and are at steady state by the second or third day of dosing.

With single daily applications of AndroGel, follow-up measurements 30, 90 and 180 days after starting treatment have confirmed that serum testosterone concentrations are generally maintained within the eugonadal range. Figure 1 summarizes the 24-hour pharmacokinetic profiles of testosterone for hypogonadal men ( < 300 ng/dL) maintained on 5 g or 10 g of AndroGel for 30 days. The average (± SD) daily testosterone concentration produced by AndroGel 10 g on Day 30 was 792 (± 294) ng/dL and by AndroGel 5 g 566 (± 262) ng/dL.

Figure 1: Mean (± SD) Steady-State Serum Testosterone Concentrations on Day 30 in Patients Applying AndroGel Once Daily

Mean (± SD) Steady-State Serum Testosterone Concentrations - Illustration

When AndroGel treatment is discontinued after achieving steady state, serum testosterone levels remain in the normal range for 24 to 48 hours but return to their pretreatment levels by the fifth day after the last application.

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 bound to albumin and other proteins.

Metabolism

There is considerable variation in the half-life of testosterone as reported in the literature, ranging from 10 to 100 minutes. Testosterone is metabolized to various 17-keto steroids through two different pathways. The major active metabolites of testosterone are estradiol and DHT.

DHT concentrations increased in parallel with testosterone concentrations during AndroGel treatment. After 180 days of treatment in adult males, mean DHT concentrations were within the normal range with 5 g AndroGel and were about 7% above the normal range after a 10 g dose. The mean steady-state DHT/T ratio during 180 days of AndroGel treatment remained within normal limits and ranged from 0.23 to 0.29 (5 g/day) and from 0.27 to 0.33 (10 g/day).

Excretion

About 90% of a dose of testosterone given intramuscularly is excreted in the urine as glucuronic 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.

Clinical Studies

Clinical Trials in Adult Hypogonadal Males

AndroGel was evaluated in a multi-center, randomized, parallel-group, active-controlled, 180-day trial in 227 hypogonadal men. The study was conducted in 2 phases. During the Initial Treatment Period (Days 1-90), 73 patients were randomized to AndroGel 5 g daily, 78 patients to AndroGel 10 g daily, and 76 patients to a non-scrotal testosterone transdermal system. The study was double-blind for dose of AndroGel but open-label for active control. Patients who were originally randomized to AndroGel and who had single-sample serum testosterone levels above or below the normal range on Day 60 were titrated to 7.5 g daily on Day 91. During the Extended Treatment Period (Days 91-180), 51 patients continued on AndroGel 5 g daily, 52 patients continued on AndroGel 10 g daily, 41 patients continued on a non-scrotal testosterone transdermal system (5 mg daily), and 40 patients received AndroGel 7.5 g daily. Upon completion of the initial study, 163 enrolled and 162 patients received treatment in an open-label extension study of AndroGel for an additional period of up to 3 years.

Mean peak, trough and average serum testosterone concentrations within the normal range (298-1043 ng/dL) were achieved on the first day of treatment with doses of 5 g and 10 g. In patients continuing on AndroGel 5 g and 10 g, these mean testosterone levels were maintained within the normal range for the 180-day duration of the original study. Figure 2 summarizes the 24-hour pharmacokinetic profiles of testosterone administered as AndroGel for 30, 90 and 180 days. Testosterone concentrations were maintained as long as the patient continued to properly apply the prescribed AndroGel treatment.

Figure 2: Mean Steady-State Testosterone Concentrations in Patients with Once-Daily AndroGel Therapy

Mean Steady-State Testosterone Concentrations in Patients with Once-Daily AndroGel Therapy - Illustration

Table 5 summarizes the mean testosterone concentrations on Treatment Day 180 for patients receiving 5 g, 7.5 g, or 10 g of AndroGel. The 7.5 g dose produced mean concentrations intermediate to those produced by 5 g and 10 g of AndroGel.

Table 5: Mean (± SD) Steady-State Serum Testosterone Concentrations During Therapy (Day 180)

  5g 7.5 g 10 g
  N = 44 N = 37 N = 48
Cavg 555 ±225 601 ±309 713 ±209
Cmax 830 ± 347 901 ±471 1083 ±434
Cmin 371 ± 165 406 ±220 485 ±156

Of 129 hypogonadal men who were appropriately titrated with AndroGel and who had sufficient data for analysis, 87% achieved an average serum testosterone level within the normal range on Treatment Day 180.

In patients treated with AndroGel, there were no observed differences in the average daily serum testosterone concentrations at steady-state based on age, cause of hypogonadism, or body mass index.

AndroGel 5 g/day and 10 g/day resulted in significant increases over time in total body mass and total body lean mass, while total body fat mass and the percent body fat decreased significantly. These changes were maintained for 180 days of treatment during the original study. Changes in the 7.5 g dose group were similar. Bone mineral density in both hip and spine increased significantly from Baseline to Day 180 with 10 g AndroGel.

AndroGel treatment at 5 g/day and 10 g/day for 90 days produced significant improvement in libido (measured by sexual motivation, sexual activity and enjoyment of sexual activity as assessed by patient responses to a questionnaire). The degree of penile erection as subjectively estimated by the patients, increased with AndroGel treatment, as did the subjective score for "satisfactory duration of erection." AndroGel treatment at 5 g/day and 10 g/day produced positive effects on mood and fatigue. Similar changes were seen after 180 days of treatment and in the group treated with the 7.5 g dose. DHT concentrations increased in parallel with testosterone concentrations at AndroGel doses of 5 g/day and 10 g/day, but the DHT/T ratio stayed within the normal range, indicating enhanced availability of the major physiologically active androgen. Serum estradiol (E2) concentrations increased significantly within 30 days of starting treatment with AndroGel 5 or 10 g/day and remained elevated throughout the treatment period but remained within the normal range for eugonadal men. Serum levels of SHBG decreased very slightly (1 to 11%) during AndroGel treatment. In men with hypergonadotropic hypogonadism, serum levels of LH and FSH fell in a dose- and time-dependent manner during treatment with AndroGel.

Phototoxicity in Humans

The phototoxic potential of AndroGel was evaluated in a double-blind, single-dose study in 27 subjects with photosensitive skin types. The Minimal Erythema Dose (MED) of ultraviolet radiation was determined for each subject. A single 24 (+1) hour application of duplicate patches containing test articles (placebo gel, testosterone gel, or saline) was made to naive skin sites on Day 1. On Day 2, each subject received five exposure times of ultraviolet radiation, each exposure being 25% greater than the previous one. Skin evaluations were made on Days 2 to 5. Exposure of test and control article application sites to ultraviolet light did not produce increased inflammation relative to non-irradiated sites, indicating no phototoxic effect.

Testosterone Transfer from Male Patients to Female Partners

The potential for dermal testosterone transfer following AndroGel use was evaluated in a clinical study between males dosed with AndroGel and their untreated female partners. Two (2) to 12 hours after AndroGel (10 g) application by the male subjects, the couples (N = 38 couples) engaged in daily, 15-minute sessions of vigorous skin-to-skin contact so that the female partners gained maximum exposure to the AndroGel application sites. Under these study conditions, all unprotected female partners had a serum testosterone concentration > 2 times the baseline value at some time during the study. When a shirt covered the application site(s), the transfer of testosterone from the males to the female partners was completely prevented.

TESTOSTERONE GEL - TRANSDERMAL

(tess-TOSS-ter-own)

COMMON BRAND NAME(S): Androgel, Testim

WARNING: Children accidentally exposed to this medication by direct contact with someone using it may absorb this drug through their skin. If this occurs, the child may have unwanted side effects due to testosterone gel. Children should avoid contact with the unwashed or unclothed area where the medication has been applied. Tell both of your doctors immediately if you notice unexpected signs of puberty in a child such as unusual increase in size of genitals (penis or clitoris), early development of pubic hair, increased erections (in boys) or sex drive, or aggressive behavior. To decrease this risk, carefully follow all directions for the proper use of this drug.

USES: This medicated gel contains testosterone. It is used for hormone replacement in men who are not able to produce enough testosterone (e.g., hypogonadism). This medication is absorbed through the skin, enters your bloodstream, and helps your body reach normal testosterone levels.

Testosterone helps the body to produce sperm and to develop and maintain the male sexual characteristics (masculinity), such as a deep voice and body hair. It also helps to maintain muscle and prevent bone loss, and is necessary for natural sexual ability/desire.

This drug should not be used by women.

HOW TO USE: Read the Medication Guide and, if available, the Patient Information Leaflet provided by your pharmacist before you start using testosterone gel and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Apply the medication as directed to clean, dry skin of the shoulders/upper arms once daily in the morning or as directed by your doctor. Apply only to areas that would be covered if you were to wear a short sleeve t-shirt. Certain brands of this medication may also be applied to the stomach area (abdomen). Check your product's instructions or ask your pharmacist if your brand may be applied to the abdomen. Avoid applying this medication to broken, irritated skin. Do not apply to the genitals (penis or scrotum). Do not let others apply this medication to your body.

Dosage is based on your medical condition and response to treatment.

After applying this medication, wash your hands thoroughly with soap and water to reduce the risk of accidentally spreading it from your hands to other people. Before dressing, wait a few minutes for the application site to dry completely. Be sure to always wear clothing (such as a t-shirt) to cover the application site until you wash the areas well with soap and water.

To get the best effect, wait several hours (2 to 5 hours depending on brand) before showering/swimming to allow the drug to be absorbed through the skin. Check the manufacturer's information or ask your pharmacist for details. See also Warning and Precautions sections.

Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time each day.

This medication is flammable until dry. Let the gel dry before smoking or going near an open flame.

Tell your doctor if your condition does not improve or if it worsens.

How should I use testosterone topical?

Use exactly as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.

This medication comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.

Apply the testosterone topical (transdermal) patch to a flat, clean, dry, and undamaged area of skin on your back, stomach, upper arm, or thigh. Wear the patch for 24 hours and then replace it with a new patch. Apply your patch at the same time each evening.

Choose a different skin area to wear each new patch you put on. You should not use the same skin area twice in a 7-day period.

After removing a patch, fold it closed with the sticky side in, and throw it away in a place where pets and children cannot reach it.

Apply the testosterone gel at the same time each day (preferably in the morning) to clean, dry, unbroken skin on the shoulders or upper arms. Open the gel pouch, and squeeze the entire contents onto the palm of your hand. Apply the gel right away and allow it to dry for at least 5 minutes before you dress. Wash your hands with soap and water after applying the gel.

Do not apply testosterone gel to your penis or your scrotum. The Testim brand of testosterone gel should also not be applied to your stomach area.

It is best to cover treated skin areas with clothing while using testosterone gel. This will help prevent getting this medicine on other people. If someone else does come into contact with a treated skin area, they must wash the contact area right away with soap and water.

To be sure this medicine is helping your condition, your blood will need to be tested often. Your prostate or liver function may also need to be tested. Visit your doctor regularly.

Use testosterone topical regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.

Store at room temperature away from moisture and heat. Keep each skin patch in the foil pouch until you are ready to use it. Do not use a skin patch that has been cut or damaged.

Apply the gel or skin patch as soon as you remember. Skip the missed dose if it is almost time to apply your next dose. Do not use extra patches or gel to make up the missed dose.

If a transdermal patch falls off in the morning, reapply it. If it does not stick well, apply a new patch. If the patch falls off in the afternoon and cannot be reapplied, wait until your regular patch replacement time in the evening before putting on a new patch.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

If your doctor recommends a topical steroid medicine such as hydrocortisone to treat skin irritation caused by wearing a testosterone skin patch, avoid using an ointment form of the steroid.
