BRAVELLE vs HUMEGON
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bravelle (urofollitropin) is a purified preparation of follicle-stimulating hormone (FSH) that stimulates ovarian follicular growth and maturation by binding to FSH receptors on granulosa cells, increasing cAMP production and promoting follicular development.
HUMEGON (menotropins) is a purified preparation of gonadotropins (follicle-stimulating hormone, FSH, and luteinizing hormone, LH) extracted from the urine of postmenopausal women. It acts by stimulating ovarian follicular growth and maturation in women and spermatogenesis in men via binding to FSH and LH receptors on target cells.
For ovulation induction: 150 IU subcutaneously or intramuscularly once daily for 5 days, starting on day 3 or 5 of menstrual cycle. For controlled ovarian hyperstimulation: 150-225 IU subcutaneously or intramuscularly once daily for 5-7 days, then adjust based on response.
75 to 150 IU subcutaneously or intramuscularly once daily for 7 to 12 days, adjusted based on follicular response.

Terminal elimination half-life approximately 5-6 hours in healthy adults. Extended in renal impairment (up to 24 hours with CrCl <30 mL/min).
Terminal half-life approximately 23-24 hours (range 20-30 h) for FSH and LH activity; clinical significance: once-daily dosing achieves steady-state in 4-5 half-lives (approx. 5 days).
Primarily renal: 95% of administered dose excreted unchanged in urine within 24 hours. Biliary/fecal: 5% eliminated via feces.
Primarily renal (90-95% as intact hormone and metabolites); biliary/fecal excretion minor (<5%).
