Cetrorelix acetate is an injectable gonadotropin-releasing hormone antagonist (GnRH antagonist). A synthetic decapeptide, it is used to treat hormone-sensitive cancers of the prostate and breast (in pre-/perimenopausal women) and some benign gynaecological disorders (endometriosis, uterine fibroids and endometrial thinning). In addition, cetrorelix is used in assisted reproduction to inhibit premature luteinizing hormone surges. The drug works by blocking the action of GnRH upon the pituitary, thus rapidly suppressing the production and action of LH and FSH. 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 hCG is not administered within four days, a daily 0.25 mg dose is started and continued until hCG is administered.
