Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Androgen receptor agonist; testicular androgen responsible for development and maintenance of male sex characteristics and anabolic effects; increases protein synthesis and muscle mass.
Apalutamide is a nonsteroidal antiandrogen that inhibits androgen receptor (AR) nuclear translocation, DNA binding, and transcription of AR target genes. It also decreases AR-mediated tumor cell proliferation and increases apoptosis.
Male hypogonadism (primary and hypogonadotropic),Delayed puberty in males,Off-label: Androgen replacement in transgender men (masculinizing hormone therapy)
Metastatic castration-sensitive prostate cancer (m CSPC),Non-metastatic castration-resistant prostate cancer (nm CRPC)
Testosterone undecanoate 750 mg (3 m L) intramuscular injection every 10 weeks, or testosterone cypionate 50-400 mg intramuscular injection every 2-4 weeks. For gel formulations: 50-100 mg transdermally once daily.
240 mg orally once daily with or without food.
8 hours; clinical context: steady-state achieved in 2-3 days, dosing interval 8-12 hours.
Terminal elimination half-life is approximately 3 days (72 hours) for apalutamide and 3–5 days for the active metabolite N-desmethyl-apalutamide. The long half-life supports once-daily dosing and requires approximately 2–3 weeks to reach steady state.
Hepatic metabolism via CYP3A4; undergoes extensive first-pass metabolism; metabolites primarily excreted renally.
Primarily metabolized by CYP2C8 and CYP3A4 to active metabolite N-desmethylapalutamide. Also involves glucuronidation by UGTs.
Renal: 90% as glucuronide and sulfate conjugates, 6% as unchanged drug; fecal: 4%.
Apalutamide and its active metabolite N-desmethyl-apalutamide are eliminated primarily via hepatic metabolism and subsequent fecal excretion. Approximately 65% of the dose is recovered in feces (as unchanged drug and metabolites) and 24% in urine (primarily as metabolites). Renal excretion of unchanged drug is negligible.
97-99% bound primarily to sex hormone-binding globulin (SHBG) and albumin.
Apalutamide is highly protein bound (>96%), primarily to albumin and alpha-1-acid glycoprotein. No significant displacement interactions are expected with other highly bound drugs.
0.5-1.0 L/kg; indicates extensive distribution into tissues and organs.
Apparent volume of distribution (Vd/F) is approximately 200 L (2.7 L/kg for a 70 kg adult), indicating extensive distribution into tissues including the prostate and other androgen-responsive organs.
Oral: low (variable, ~5-20% due to first-pass metabolism); intramuscular: 100%.
Oral bioavailability is not precisely determined due to lack of an intravenous formulation, but absorption is at least 90% based on mass balance studies. Food does not significantly affect absorption, so it can be taken with or without food.
No specific dose adjustment required for renal impairment; monitor serum testosterone levels and clinical response. For severe renal impairment (GFR <30 m L/min), consider increased monitoring due to potential fluid retention.
No dose adjustment required for mild to moderate renal impairment (e GFR 30-89 m L/min). For severe renal impairment (e GFR 15-29 m L/min), use with caution; no specific dose recommendation. Not studied in end-stage renal disease (e GFR <15 m L/min) or on hemodialysis.
Contraindicated in patients with severe hepatic dysfunction (Child-Pugh class C). For mild to moderate impairment (Child-Pugh class A or B), use with caution and consider dose reduction; monitor liver function tests regularly.
Mild hepatic impairment (Child-Pugh A): No dose adjustment. Moderate hepatic impairment (Child-Pugh B): Reduce dose to 120 mg once daily. Severe hepatic impairment (Child-Pugh C): Not recommended due to lack of data.
Not recommended for use in children; safety and efficacy not established. For delayed puberty in adolescent males: testosterone enanthate 50-200 mg intramuscularly every 2-4 weeks, titrated to response, with monitoring of bone age.
Safety and efficacy not established; no approved pediatric dosing.
Start at low end of dosing range (e.g., testosterone cypionate 50 mg intramuscularly every 4 weeks or gel 25 mg daily) due to potential increased sensitivity and risk of prostatic hypertrophy or cardiovascular events. Monitor serum testosterone, hematocrit, and prostate-specific antigen (PSA).
No specific dose adjustment required; consider comorbidities and potential for increased adverse effects based on renal and hepatic function.
None
None.
Risk of hepatotoxicity; use with caution in patients with liver disease. Monitor liver function, lipid profile, and prostate-specific antigen (PSA). May cause fluid retention, gynecomastia, priapism, and sleep apnea. Not for use in women who are pregnant or breastfeeding. May accelerate growth of prostate cancer and benign prostatic hyperplasia. Androgenic effects may cause virilization in women.
Seizures: Discontinue permanently if seizure occurs during treatment.,Fractures and Falls: Increased risk of bone fractures and falls; assess bone density and manage accordingly.,Cardiovascular Events: Increased risk of hypertension, cardiac ischemia, and heart failure; monitor cardiovascular status.,Hypothyroidism: Monitor thyroid function before and during treatment; replacement therapy may be needed.,Embryo-Fetal Toxicity: Can cause fetal harm; advise males with female partners of reproductive potential to use effective contraception.
Men with carcinoma of the prostate or breast; history of hypersensitivity to testosterone or any component; women who are pregnant or may become pregnant (risk of fetal harm); patients with severe hepatic or cardiac disease.
Pregnancy (can cause fetal harm),Women of reproductive potential (unless using effective contraception)
No known food interactions. However, methyltestosterone can increase appetite and cause weight gain; a balanced diet is recommended.
Avoid grapefruit and grapefruit juice due to potential CYP3A4 interaction. No other specific dietary restrictions; can be taken with or without food.
Android 10 is a combination of methyltestosterone and ethinyl estradiol. Methyltestosterone is an androgen; exposure during pregnancy, particularly during the first trimester, can cause virilization of the female fetus. Ethinyl estradiol is contraindicated in pregnancy due to risk of fetal harm. Use is contraindicated in all trimesters.
Apalutamide is contraindicated in pregnancy. Based on its mechanism of androgen receptor inhibition, it may cause fetal harm, including feminization of male fetuses and developmental abnormalities. Adequate animal reproduction studies have not been conducted; however, in rats, fetal malformations were observed at exposures below human clinical exposures. Effective contraception is required for females of reproductive potential during treatment and for 3 months after the last dose.
Methyltestosterone and ethinyl estradiol are excreted in breast milk. Methyltestosterone may cause virilization in female infants. Ethinyl estradiol may reduce milk production and quality. M/P ratio not available. Breastfeeding is contraindicated.
It is unknown whether apalutamide or its metabolites are excreted in human milk. Due to potential for serious adverse reactions in breastfed infants, breastfeeding is not recommended during treatment and for at least 3 months after the last dose. M/P ratio is not available.
Contraindicated in pregnancy; no dosing adjustments apply. If inadvertent use occurs, discontinue immediately.
No dosing adjustments have been established for pregnancy. Apalutamide is not indicated for use in pregnant women. Physiological changes in pregnancy may alter pharmacokinetics, but no data are available to guide dose modifications.
Android 10 is a brand name for methyltestosterone, an androgen and anabolic steroid. Use is restricted to replacement therapy in males with hypogonadism or delayed puberty due to androgen deficiency. Monitor liver function due to risk of peliosis hepatis and hepatocellular carcinoma. Contraindicated in males with breast or prostate cancer. Can cause erythrocytosis; monitor hematocrit. Discontinue if signs of virilization in women or priapism in men. Use caution in elderly due to increased risk of prostatic hypertrophy.
Apalutamide is an androgen receptor inhibitor used for non-metastatic castration-resistant prostate cancer (nm CRPC). It is a strong CYP3A4 inducer and moderate CYP2C8 inhibitor, requiring careful management of drug interactions. Monitor thyroid function and blood pressure. Concomitant use with warfarin or other anticoagulants may necessitate increased monitoring due to reduced efficacy. Apalutamide can cause seizures; avoid in patients with history of seizure disorders. Baseline and periodic serum lipid profiles and glucose levels are recommended. Dose reduction in severe hepatic impairment (Child-Pugh C) is suggested.
