Overview

â„šī¸

What is this medicine?

Testosterone gel is a medication applied to the skin to replace the natural hormone testosterone in men who have low levels (hypogonadism). It helps improve symptoms like low energy, low sex drive, and muscle weakness. It's important to apply it correctly and prevent others, especially women and children, from coming into contact with the treated skin.

Pharmacology

đŸ”Ŧ

Mechanism of Action

Testosterone is an endogenous androgen responsible for the normal growth and development of male sex organs and for maintenance of secondary sex characteristics. It acts by binding to androgen receptors in target tissues, forming a hormone-receptor complex that translocates to the nucleus and interacts with DNA to regulate gene expression, leading to androgenic and anabolic effects.
📊

Pharmacokinetics

Absorption:

Bioavailability: Approximately 9-14% (transdermal absorption varies)
Tmax: Approximately 4 hours (for serum testosterone after application)
FoodEffect: Not applicable for transdermal gel.

Distribution:

Vd: Approximately 1 L/kg
ProteinBinding: Approximately 98% (primarily to sex hormone-binding globulin [SHBG] and albumin)
CnssPenetration: Limited (metabolized to active metabolites in CNS)

Elimination:

HalfLife: Approximately 10-100 minutes (endogenous testosterone); effective half-life after transdermal application is longer due to continuous absorption from skin reservoir.
Clearance: Approximately 13.2 L/hr
ExcretionRoute: Approximately 90% in urine (as conjugates of testosterone and its metabolites), 6% in feces (unconjugated metabolites)
Unchanged: Less than 6% (in urine)
âąī¸

Pharmacodynamics

OnsetOfAction: Within days to weeks for clinical effects (e.g., libido, energy); serum levels stabilize within 2-3 days.
PeakEffect: Weeks to months for full therapeutic effects.
DurationOfAction: Daily application maintains therapeutic levels.

Safety & Warnings

âš ī¸

BLACK BOX WARNING

WARNING: SECONDARY EXPOSURE TO TESTOSTERONE
Virilization in children and women can occur following secondary exposure to testosterone gel. Cases of secondary exposure have been reported in children ranging from 9 months to 10 years of age and have resulted in adverse events including pubic hair development, enlarged penis or clitoris, premature pubarche, accelerated bone age, increased libido, and aggressive behavior. In most cases, these signs and symptoms regressed with removal of the testosterone exposure. In some cases, enlarged genitalia did not fully return to age-appropriate normal size. Secondary exposure to testosterone gel can also occur in women. Adverse events reported in women include deepening of the voice, hirsutism, acne, clitoromegaly, and changes in menstrual cycles. To minimize the potential for secondary exposure, patients should be advised to wash their hands immediately with soap and water after application of testosterone gel and to cover the application site with clothing once the gel has dried. See WARNINGS and PRECAUTIONS for additional information.

Monitoring

đŸ”Ŧ

Baseline Monitoring

Serum Testosterone (total and free)

Rationale: To confirm diagnosis of hypogonadism and establish baseline levels.

Timing: Before initiation of therapy, typically in the morning.

Hematocrit/Hemoglobin

Rationale: To assess for polycythemia, a common adverse effect of testosterone therapy.

Timing: Before initiation of therapy.

Prostate-Specific Antigen (PSA)

Rationale: To screen for prostate cancer, as testosterone can stimulate prostate growth.

Timing: Before initiation of therapy (in men â‰Ĩ40 years old).

Digital Rectal Exam (DRE)

Rationale: To screen for prostate abnormalities.

Timing: Before initiation of therapy (in men â‰Ĩ40 years old).

Lipid Panel

Rationale: To assess cardiovascular risk factors, as testosterone may affect lipid profiles.

Timing: Before initiation of therapy.

📊

Routine Monitoring

Serum Testosterone (total)

Frequency: Approximately 14 days after initiation or dose adjustment, then periodically (e.g., every 3-6 months) once stable.

Target: 300-1000 ng/dL (or within the mid-normal range for healthy young men)

Action Threshold: If levels are consistently above 1000 ng/dL, reduce dose or discontinue. If levels are consistently below 300 ng/dL, consider dose increase.

Hematocrit/Hemoglobin

Frequency: At 3-6 months after initiation, then annually.

Target: <54%

Action Threshold: If hematocrit >54%, reduce dose, discontinue temporarily, or perform phlebotomy.

PSA and DRE

Frequency: At 3-6 months after initiation, then annually (in men â‰Ĩ40 years old).

Target: Stable or within normal limits for age.

Action Threshold: Significant increase in PSA or abnormal DRE warrants further urological evaluation.

Lipid Panel

Frequency: Annually.

Target: Within normal limits.

Action Threshold: Significant adverse changes may require intervention or re-evaluation of therapy.

đŸ‘ī¸

Symptom Monitoring

  • Signs of fluid retention (e.g., ankle swelling, weight gain)
  • Symptoms of benign prostatic hyperplasia (BPH) worsening (e.g., urinary frequency, urgency, nocturia)
  • Signs of sleep apnea worsening
  • Mood changes, irritability, aggression
  • Breast tenderness or enlargement (gynecomastia)
  • Skin reactions at application site (e.g., redness, irritation)
  • Signs of secondary exposure in women or children (e.g., virilization in women, premature puberty in children)

Special Patient Groups

🤰

Pregnancy

Testosterone is contraindicated in pregnant women. It can cause virilization of the female fetus.

Trimester-Specific Risks:

First Trimester: High risk of virilization of female fetus.
Second Trimester: High risk of virilization of female fetus.
Third Trimester: High risk of virilization of female fetus.
🤱

Lactation

Testosterone is contraindicated in breastfeeding women. It is unknown if testosterone is excreted in human milk, but due to the potential for serious adverse reactions in the nursing infant, it should not be used.

Infant Risk: High risk of virilization and other adverse effects.
đŸ‘ļ

Pediatric Use

Contraindicated in children due to the risk of adverse effects on bone maturation (premature epiphyseal closure) and sexual development (precocious puberty). Safety and efficacy have not been established.

👴

Geriatric Use

No specific dose adjustment is typically required based on age alone. However, geriatric patients may be at increased risk for prostate enlargement, prostate cancer, and cardiovascular events. Close monitoring of PSA, DRE, hematocrit, and cardiovascular status is recommended.

Clinical Information

💎

Clinical Pearls
