HUMEGON vs OVIDREL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
OVIDREL (choriogonadotropin alfa) acts as a luteinizing hormone (LH) agonist, binding to the LH/choriogonadotropin receptor on ovarian theca and granulosa cells, triggering ovulation and luteinization by inducing resumption of oocyte meiosis and follicle rupture.
75 to 150 IU subcutaneously or intramuscularly once daily for 7 to 12 days, adjusted based on follicular response.
250 mcg subcutaneously once daily for 7 days following recombinant FSH stimulation. Alternatively, a single 250 mcg subcutaneous dose is used to trigger final follicular maturation 24-48 hours after last gonadotropin dose.

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).
The terminal elimination half-life is approximately 30 hours (range 20-48 hours) in healthy adults. This supports a single-dose regimen for final follicular maturation in assisted reproductive technology.
Primarily renal (90-95% as intact hormone and metabolites); biliary/fecal excretion minor (<5%).
Primarily renal, with approximately 10% of the administered dose excreted unchanged in urine within 24 hours. The remainder undergoes metabolic degradation in the kidneys and liver.
