Usage: Is to promote the GnRH receptor antagonist
Cetrorelix acetate is the acetic acid salt of cetrorelix. A gonadotrophin-releasing hormone (GnRH) antagonist, it is used for treatment of infertility and of hormone-sensitive cancers of the prostate and breast. It has a role as a GnRH antagonist and an antineoplastic agent. It is an oligopeptide and an acetate salt. It contains a cetrorelix.
