Androgen receptor agonist; stimulates protein synthesis and growth of androgen-sensitive tissues.
BAROS (burosumab) is a recombinant human monoclonal antibody that binds to and inhibits fibroblast growth factor 23 (FGF23). By neutralizing excess FGF23, it increases renal phosphate reabsorption and enhances production of 1,25-dihydroxyvitamin D, thereby correcting hypophosphatemia and improving bone mineralization.
Testosterone replacement therapy for male hypogonadism,Off-label: delayed puberty in males
Treatment of X-linked hypophosphatemia (XLH) in adult and pediatric patients aged 1 year and older,Treatment of FGF23-related hypophosphatemia in tumor-induced osteomalacia (TIO) associated with phosphaturic mesenchymal tumors that cannot be curatively resected or localized
2.5-10 mg orally once daily in the morning for androgen replacement therapy in adult males.
None established.
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 in renal impairment (up to 30 hours in severe cases).
Hepatic via CYP3A4 and CYP2B6; undergoes first-pass metabolism.
Metabolized via general protein catabolism; not metabolized by CYP450 enzymes.
Primarily renal: ~90% as glucuronide and sulfate conjugates, 6% as unchanged drug; ~5% fecal via bile.
Renal excretion of unchanged drug accounts for 80-90% of elimination; biliary/fecal excretion accounts for 5-10%.
98% bound to sex hormone-binding globulin (SHBG) and albumin.
85-90% bound to albumin.
Vd approximately 1.0 L/kg; indicates extensive tissue distribution, especially to reproductive organs and bone marrow.
0.3-0.5 L/kg, indicating distribution primarily into extracellular fluid.
Oral: 15–25% due to first-pass metabolism; buccal or transdermal: higher, but not commercially available for this formulation.
Oral: 60-80% (first-pass metabolism reduces 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 data available.
Contraindicated in Child-Pugh class B and C cirrhosis due to hepatotoxicity risk; in class A, use with caution and monitor liver function.
No data available.
Not recommended for use in children as it may cause premature epiphyseal closure and virilization; limited data.
No data available.
Increased risk of prostatic hyperplasia and carcinoma; use lowest effective dose with regular prostate monitoring.
No data available.
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.
Hyperphosphatemia and risk of nephrocalcinosis/nephrolithiasis: monitor serum phosphorus and renal function,Severe hypersensitivity reactions including anaphylaxis,Potential for injection site reactions,Risk of hyperphosphatemia in patients with severe renal impairment,May increase risk of infections; avoid live vaccines during treatment
Known or suspected prostate cancer; breast cancer in males; hypersensitivity to androgens; pregnancy and lactation.
Concomitant use with oral phosphate and active vitamin D analogs (e.g., calcitriol, phosphate supplements) except during initial titration or adjustment when hypophosphatemia is severe,Severe renal impairment or end-stage renal disease (e GFR <30 m L/min/1.73 m²),Known hypersensitivity to burosumab or any excipients
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.
High-fat meals (>30% of calories from fat) increase the incidence of gastrointestinal adverse effects such as oily spotting, flatus with discharge, and steatorrhea. Dietary fat intake should be distributed over three main meals. The drug is most effective when combined with a reduced-calorie, low-fat diet. Foods rich in fat-soluble vitamins (A, D, E, K) should be consumed with a multivitamin supplement taken at bedtime to prevent deficiency.
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.
BAROS is contraindicated in pregnancy due to teratogenicity. First trimester: high risk of cardiac, CNS, and skeletal defects. Second/third trimesters: risk of fetal growth restriction and oligohydramnios. Animal studies show dose-dependent embryotoxicity. Human data limited but indicates significant risk.
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 breast milk; M/P ratio = 1.2. Avoid breastfeeding due to potential for infant toxicity. If unavoidable, monitor infant for drowsiness and poor feeding.
Not applicable; contraindicated in pregnancy. No dose adjustment recommendations exist for pregnant patients.
Increased clearance in pregnancy (by 30%) due to enhanced hepatic metabolism and renal blood flow. Dose must be increased by 25-50% in the second and third trimesters, guided by therapeutic drug monitoring.
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.
BAROS is a brand name for orlistat, a reversible inhibitor of gastric and pancreatic lipases. It reduces dietary fat absorption by approximately 30% at the therapeutic dose of 120 mg three times daily. Monitor for fat-soluble vitamin deficiencies (A, D, E, K) and consider supplementation. Advise patients to take a multivitamin containing these vitamins at bedtime, at least 2 hours after the last dose. BAROS can cause oily spotting, flatus with discharge, fecal urgency, and steatorrhea, especially if dietary fat intake exceeds 30% of total calories. Contraindicated in chronic malabsorption syndrome and cholestasis. Use with caution in patients with a history of hyperoxaluria or calcium oxalate kidney stones.
Take exactly as prescribed; do not increase dose or frequency without consulting your doctor.,Report any signs of liver problems: yellowing of skin or eyes, dark urine, severe stomach pain.,Women should report any signs of virilization: hoarseness, acne, menstrual changes, growth of facial hair.,Men should report any breast enlargement, changes in urination, or priapism.,Avoid driving or operating machinery if you experience dizziness or drowsiness.,Do not use if you are pregnant or planning to become pregnant.
Take BAROS with each main meal containing fat, up to three times daily.,If you miss a meal or eat a fat-free meal, skip the dose.,Follow a reduced-calorie, low-fat diet (less than 30% of calories from fat) to minimize gastrointestinal side effects.,You may experience oily stools, gas with discharge, or an urgent need to have a bowel movement. These effects are common and often improve with time.,Take a daily multivitamin that contains vitamins A, D, E, and K at bedtime, at least 2 hours after your last dose of BAROS.,BAROS may reduce absorption of some medications; separate administration by at least 2 hours.,If you are taking cyclosporine or levothyroxine, take them at least 3 hours apart from BAROS.,Do not use BAROS if you are pregnant, breastfeeding, or have chronic malabsorption syndrome or gallbladder problems.,Contact your healthcare provider if you develop severe abdominal pain, rectal bleeding, or signs of kidney stones (e.g., pain during urination, back pain).
