2.5-10 mg orally once daily in the morning for androgen replacement therapy in adult males.
ANDEMBRY (capivasertib) 400 mg orally twice daily, taken with or without food, in combination with fulvestrant. Continue until disease progression or unacceptable toxicity.
Terminal elimination half-life is 3.5–5.5 hours; clinical effects may persist for several days due to active metabolites.
Terminal elimination half-life is 12-15 hours in healthy adults; may be prolonged up to 20-25 hours in patients with moderate to severe hepatic impairment.
Hepatic via CYP3A4 and CYP2B6; undergoes first-pass metabolism.
Hepatic via CYP3A4; active metabolites include abiraterone sulfate, abiraterone N-oxide, and abiraterone glucuronide.
Primarily renal: ~90% as glucuronide and sulfate conjugates, 6% as unchanged drug; ~5% fecal via bile.
Primarily renal excretion of unchanged drug (approximately 70-80%) and as metabolites (10-15%); biliary/fecal elimination accounts for less than 10%.
98% bound to sex hormone-binding globulin (SHBG) and albumin.
Approximately 95% bound to plasma proteins, primarily albumin and alpha-1-acid glycoprotein.
Vd approximately 1.0 L/kg; indicates extensive tissue distribution, especially to reproductive organs and bone marrow.
Volume of distribution is 0.6-0.8 L/kg, indicating distribution into total body water and some tissue binding.
Oral: 15–25% due to first-pass metabolism; buccal or transdermal: higher, but not commercially available for this formulation.
Oral bioavailability is 85-90%; intravenous administration yields 100% bioavailability.
No specific dose adjustment required based on GFR; caution in severe impairment (Cr Cl <30 m L/min) due to potential fluid retention.
No dose adjustment required for mild-to-moderate renal impairment (Cr Cl ≥30 m L/min). Not studied in severe renal impairment (Cr Cl <30 m L/min) or end-stage renal disease; avoid use.
Contraindicated in Child-Pugh class B and C cirrhosis due to hepatotoxicity risk; in class A, use with caution and monitor liver function.
Mild hepatic impairment (Child-Pugh A): no dose adjustment. Moderate hepatic impairment (Child-Pugh B): reduce dose to 320 mg orally twice daily. Severe hepatic impairment (Child-Pugh C): not recommended.
Not recommended for use in children as it may cause premature epiphyseal closure and virilization; limited data.
Safety and efficacy not established in pediatric patients (<18 years); no recommended dose.
Increased risk of prostatic hyperplasia and carcinoma; use lowest effective dose with regular prostate monitoring.
No specific dose adjustment required based on age. Monitor renal function and for increased risk of adverse events (e.g., diarrhea, hyperglycemia) in elderly patients.
Warning: Prolonged use may cause virilization in women, premature epiphyseal closure, and increased risk of prostatic hypertrophy/carcinoma.
None.
Monitor liver function, lipid profile, and prostate-specific antigen; risk of edema in patients with cardiac disease; avoid use in patients with sleep apnea.
Hepatotoxicity, mineralocorticoid excess, cardiovascular events, adrenal insufficiency, and bone marrow suppression.
Known or suspected prostate cancer; breast cancer in males; hypersensitivity to androgens; pregnancy and lactation.
Hypersensitivity to abiraterone acetate or any component, severe hepatic impairment (Child-Pugh C), and women who are or may become pregnant.
Avoid grapefruit and grapefruit juice as they may increase drug levels. Limit salt intake to reduce fluid retention. Alcohol may increase risk of liver toxicity.
ANDEMBRY can be taken with or without food. However, grapefruit and grapefruit juice may increase trofinetide levels; avoid concurrent consumption. No other significant food interactions reported.
Pregnancy Category X. ANDROID 5 (oxandrolone) is contraindicated in pregnancy due to teratogenic effects including masculinization of female fetus, clitoral enlargement, and labial fusion. Risk is highest during first trimester but applies throughout gestation.
Category X. First trimester: Major congenital malformations (neural tube defects, craniofacial abnormalities). Second/third trimester: Spontaneous abortion, fetal death, growth restriction. Contraindicated in pregnancy.
Excretion into human milk is unknown. Due to potential for androgenic effects in nursing infants, breastfeeding is not recommended. No M/P ratio available.
Excreted in human milk; M/P ratio unknown. Potential for serious adverse effects in nursing infant. Contraindicated during breastfeeding.
Not applicable; contraindicated in pregnancy. No dose adjustment recommendations exist for pregnant patients.
Do not use in pregnancy. No dose recommendations available; contraindicated.
Android 5 (methyltestosterone) is an androgenic anabolic steroid used for hypogonadism and delayed puberty. Monitor liver function due to hepatotoxicity. Use with caution in elderly due to increased risk of prostatic hypertrophy and carcinoma. Can cause fluid retention in patients with cardiac, renal, or hepatic disease. Avoid in patients with breast cancer or known or suspected prostate cancer.
ANDEMBRY (trofinetide) is indicated for the treatment of Rett syndrome. Administer orally twice daily with or without food. Monitor for diarrhea and vomiting, which are common adverse effects; consider dose reduction or temporary discontinuation if severe. Assess liver enzymes and bilirubin before and during treatment due to potential hepatotoxicity. Avoid use in patients with severe hepatic impairment. Do not crush or chew capsules; for patients unable to swallow, sprinkle contents onto soft food and administer immediately.

Common clinical questions about ANDROID 5 vs ANDEMBRY, answered by our medical review team.
ANDROID 5 is a Androgen that works by Androgen receptor agonist; stimulates protein synthesis and growth of androgen-sensitive tissues.. ANDEMBRY is a Gonadotropin that works by Binds to androgens, progesterone, and estradiol, inhibiting their effects on hormone-responsive tissues; also binds to microtubules and inhibits tubulin polymerization.. They differ in pharmacokinetic profiles, FDA-approved indications, and side effect profiles.
Potency comparisons between ANDROID 5 and ANDEMBRY depend on the specific clinical indication. These are agents from distinct pharmacological classes and are not directly interchangeable by dose. A physician or clinical pharmacist should guide any therapeutic switching decisions.
The standard adult dose of ANDROID 5 is: 2.5-10 mg orally once daily in the morning for androgen replacement therapy in adult males.. The standard adult dose of ANDEMBRY is: ANDEMBRY (capivasertib) 400 mg orally twice daily, taken with or without food, in combination with fulvestrant. Continue until disease progression or unacceptable toxicity.. Dosing should always be individualized based on indication, renal and hepatic function, age, and other patient factors.
No direct drug-drug interaction has been formally documented between ANDROID 5 and ANDEMBRY in current clinical databases. However, individual patient risk factors including other medications, organ function, and comorbidities should always be evaluated by a qualified healthcare provider.
The maternal-fetal safety profiles differ. ANDROID 5 is classified as Category C. Pregnancy Category X. ANDROID 5 (oxandrolone) is contraindicated in pregnancy due to teratogenic effects including masculinization of female fetus, clitoral enlargement, and labial. ANDEMBRY is classified as Category C. Category X. First trimester: Major congenital malformations (neural tube defects, craniofacial abnormalities). Second/third trimester: Spontaneous abortion, fetal death, growth res. Always consult a maternal-fetal medicine specialist before taking either drug during pregnancy or lactation.
