MENOPUR vs PERGONAL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Menotropins (MENOPUR) contain follicle-stimulating hormone (FSH) and luteinizing hormone (LH) activity, which stimulate ovarian follicular growth and maturation in women, and spermatogenesis in men with hypogonadotropic hypogonadism.
Pergonal (menotropins) is a purified preparation of gonadotropins (follicle-stimulating hormone, FSH, and luteinizing hormone, LH) extracted from postmenopausal urine. It stimulates ovarian follicular growth and maturation in women and spermatogenesis in men by acting on specific gonadal receptors.
225 IU subcutaneously or intramuscularly once daily starting on day 2-3 of cycle, adjusted after 5 days based on response; maximum daily dose 450 IU.
Intramuscular administration: 75 IU daily for 7-12 days, then 5,000-10,000 IU hCG 24 hours after last dose.

The terminal elimination half-life is approximately 30-40 hours for FSH activity, reflecting the prolonged effect on follicular development; clinical dosing is adjusted based on response.
Terminal elimination half-life approximately 24-36 hours; clinical context: supports daily dosing in ovulation induction protocols.
Primarily renal excretion of unchanged drug and metabolites; approximately 80% of a dose is excreted in urine within 24 hours, with the remainder excreted in feces via biliary elimination.
Primarily renal: 70-80% as unchanged drug and metabolites within 24 hours; biliary/fecal excretion accounts for <5%.
