BRAVELLE vs REPRONEX
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.
REPRONEX (urofollitropin) is a purified preparation of follicle-stimulating hormone (FSH) that stimulates ovarian follicular growth in women who do not have primary ovarian failure. It acts by binding to FSH receptors on granulosa cells, increasing cAMP and promoting follicular development and estrogen synthesis.
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.
Men: 1000-2500 IU subcutaneously 3 times weekly for 6-12 months. Women: 75-300 IU subcutaneously or intramuscularly daily for 7-12 days.

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 elimination half-life: 24-30 hours (menotropins); clinically, it supports daily dosing during ovarian stimulation
Primarily renal: 95% of administered dose excreted unchanged in urine within 24 hours. Biliary/fecal: 5% eliminated via feces.
Renal (approximately 80% as parent drug and metabolites); biliary/fecal (<5%)
