0.5-1.0 L/kg; indicates extensive distribution into tissues and organs.
Vd/F is approximately 40–60 L (0.5–0.8 L/kg). Clinical meaning: Extensive tissue distribution, consistent with a large volume of distribution.

Oral: Approximately 30% (low due to first-pass metabolism); food increases exposure by approximately 30%.
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.
e GFR 30-89 m L/min: no adjustment. e GFR 15-29 m L/min: 100 mg twice daily. e GFR <15 m L/min: not recommended.
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.
Child-Pugh A: no adjustment. Child-Pugh B: 100 mg twice daily. Child-Pugh C: not recommended.
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.
Not established; safety and efficacy in pediatric patients have not been studied.
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; clinical studies included limited patients ≥65 years, but no differences in safety or efficacy observed.
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.
Hepatic transaminase elevations: monitor liver function before and during treatment; discontinue if elevation >3x ULN or if signs of liver injury occur.,Bone density loss: monitor bone mineral density with long-term use; consider additional calcium/vitamin D.,Mood changes: increased risk of depression, suicidal ideation; monitor for new or worsening symptoms.,Altered menstrual bleeding; exclude pregnancy before starting.,Risk of osteoporosis with prolonged use.
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.
Known hypersensitivity to elagolix or any excipients,Concomitant use with strong organic anion-transporting polypeptide (OATP) 1B1 inhibitors (e.g., cyclosporine, gemfibrozil),Pregnancy, or women of reproductive potential not using effective contraception,Existing osteoporosis or severe bone loss,History of suicidal ideation or behavior
No known food interactions. However, methyltestosterone can increase appetite and cause weight gain; a balanced diet is recommended.
Avoid grapefruit and grapefruit juice as they inhibit CYP3A4 and may increase elagolix levels. No other food restrictions.
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.
First trimester: High risk of pregnancy loss and major birth defects based on animal data and mechanism of action. Second and third trimesters: Contraindicated due to potential for harm. Elagolix is contraindicated in pregnancy.
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.
Elagolix is excreted in animal milk; no human data. M/P ratio unknown. Not recommended during breastfeeding.
Contraindicated in pregnancy; no dosing adjustments apply. If inadvertent use occurs, discontinue immediately.
No dose adjustments studied; contraindicated in pregnancy. No data on PK changes requiring dose modification.
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.
Elagolix is an oral Gn RH antagonist for endometriosis-associated pain. Monitor bone mineral density (BMD) with dual-energy X-ray absorptiometry (DXA) if using >12 months or in patients with osteoporosis risk. Avoid use with strong CYP3A inducers (e.g., rifampin) or inhibitors (e.g., ketoconazole). May reduce efficacy of hormonal contraceptives. Assess pregnancy status before starting due to teratogenicity.
Take exactly as prescribed; do not increase dose or frequency without consulting your doctor.,Report signs of liver problems: yellowing of skin or eyes, dark urine, light-colored stools, abdominal pain.,Notify your doctor if you experience swelling of ankles or feet, trouble breathing, or persistent erections lasting more than 4 hours.,May cause aggressive behavior, mood swings, or depression; contact your doctor if these occur.,Do not take if you are pregnant or breastfeeding.,Keep all appointments for blood tests and liver function monitoring.
Take elagolix at the same time daily with or without food.,Avoid grapefruit or grapefruit juice during treatment.,Use non-hormonal contraception (e.g., condoms) because elagolix may reduce hormonal contraceptive effectiveness.,Report severe headaches, vision changes, or heavy bleeding promptly.,Do not take elagolix if pregnant or planning to become pregnant; use effective birth control.
