Cetrorelix Acetate
Cat #
Introduction Cetrorelix (INN, BAN), or cetrorelix acetate (USAN, JAN), sold under the brand name Cetrotide, is an injectable gonadotropin-releasing hormone (GnRH) antagonist. A synthetic decapeptide, it is used in assisted reproduction to inhibit premature luteinizing hormone surges[1] The drug works by blocking the action of GnRH upon the pituitary, thus rapidly suppressing the production and action of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In addition, cetrorelix can be used to treat hormone-sensitive cancers of the prostate[citation needed] and breast (in pre-/perimenopausal women)[citation needed] and some benign gynaecological disorders (endometriosis, uterine fibroids and endometrial thinning).[citation needed] It is administered as either multiple 0.25 mg daily subcutaneous injections or as a single-dose 3 mg subcutaneous injection. The duration of the 3 mg single dose is four days; if human chorionic gonadotropin (hCG) is not administered within four days, a daily 0.25 mg dose is started and continued until hCG is administered.
