BRAVELLE vs FOLLISTIM AQ
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.
Recombinant human follicle-stimulating hormone (FSH) that binds to FSH receptors on granulosa cells in the ovary, stimulating follicular growth and maturation via activation of adenylyl cyclase and increased cAMP production.
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 300 IU subcutaneously once daily for 8 to 14 days, adjusted based on follicular response; maximum daily dose 450 IU and total duration not exceeding 14 days per cycle.

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 approximately 24-36 hours (subcutaneous route); clinical context supports daily dosing due to sustained follicular stimulation.
Primarily renal: 95% of administered dose excreted unchanged in urine within 24 hours. Biliary/fecal: 5% eliminated via feces.
Primarily renal (90%), with intact follitropin alfa/beta and metabolites excreted in urine; biliary/fecal excretion minimal (<10%).
