Segesterone acetate

Segesterone acetate (USAN) (brand name Nestorone; former developmental code names ST-1435, AC-6844, CS-0411), known more commonly simply as nestorone (or nestoron), and also known as elcometrine, is a steroidal progestin of the 19-norprogesterone group which is used as a hormonal contraceptive in several South American countries. Segesterone acetate is the acetate ester of segesterone, which was never marketed, but is an active metabolite of segesterone acetate. Segesterone acetate is only weakly active orally, and is instead given as a subcutaneous implant. It is more than 100-fold times as potent when delivered subcutaneously relative to orally.
