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.


Cetrorelix, a synthetic decapeptide analog of naturally occurring gonadorelin, is a gonadorelin antagonist. It competitively blocks gonadorelin receptors on the anterior piyuitary gonadotroph and the subsequent transduction pathway, inducing a rapid, reversible suppression of gonadotrophin secretion.


Duration: 4 days for a single 3-mg dose.
