For the treatment of female infertility
Choriogonadotropin alfa is used to treat female infertility, Choriogonadotropin alfa stimulates late follicular maturation and resumption of oocyte meiosis, and initiates rupture of the pre-ovulatory ovarian follicle. Ovidrel is an analogue of Luteinizing Hormone (LH) and binds to the LH/hCG receptor of the granulosa and theca cells of the ovary to effect these changes in the absence of an endogenous LH surge.
mechanism of action
Choriogonadotropin alfa binds to the Follicle stimulating hormone receptor which results in ovulation in the absence of sufficient endogenous Luteinizing hormone.
The mean absolute bioavailability following a single subcutaneous injection to healthy female volunteers is about 40%.
The mean terminal half-life is about 29 ± 6 hours (initial half-life is 4.5 ± 0.5 hours).
route of elimination
One-tenth of the dose is excreted in the urine.
