Overview
Cetrorelix acetate, a synthetic decapeptide analog of gonadotropin-releasing hormone (GnRH), is a GnRH antagonist.
Cetrorelix acetate, a synthetic decapeptide analog of naturally occurring gonadotropin-releasing hormone (GnRH, luteinizing hormone-releasing hormone, gonadorelin), is a GnRH antagonist.
Cetrorelix competitively blocks GnRH receptors on the anterior pituitary gonadotroph and the subsequent transduction pathway, inducing a rapid, reversible suppression of gonadotropin (luteinizing hormone (LH), follicle-stimulating hormone (FSH)) secretion. The suppression of pituitary LH secretion by cetrorelix is more pronounced than that of FSH. By suppressing the midcycle GnRH-induced surge in LH, cetrorelix can suppress ovulation, oocytic meiosis, and luteinization.
In women undergoing controlled ovarian stimulation, the drug can prevent the LH surges associated with such stimulation and improve implantation and pregnancy rates associated with in vitro fertilization or intracytoplasmic sperm injection (ICSI).
Following subcutaneous administration of a single 3- or 0.25-mg dose of cetrorelix, the onset of action usually occurs within 1 or 2 hours, respectively, and persists for at least 4 days or 24 hours, respectively. Cetrorelix competitively blocks GnRH receptors on the anterior pituitary gonadotroph and the subsequent transduction pathway, inducing a rapid, reversible suppression of gonadotropin (luteinizing hormone (LH), follicle-stimulating hormone (FSH)) secretion.

USES: This medication is used by women having certain fertility treatments (controlled ovarian stimulation). Cetrorelix is usually used in combination with other hormones (FSH and hCG). It works by blocking the release of a certain hormone (luteinizing hormone).
Cetrorelix stops eggs from being released too early and gives the eggs time to grow properly.
