OVIDREL vs PERGONAL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
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.
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.
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 hours (range 20-48 hours) in healthy adults. This supports a single-dose regimen for final follicular maturation in assisted reproductive technology.
Terminal elimination half-life approximately 24-36 hours; clinical context: supports daily dosing in ovulation induction protocols.
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.
Primarily renal: 70-80% as unchanged drug and metabolites within 24 hours; biliary/fecal excretion accounts for <5%.
