Megestrol (INN, BAN) is a steroidal progestin of the 17α-hydroxyprogesterone group which was never marketed and is not currently used clinically. Its acylated derivative megestrol acetate is also a progestogen, which, in contrast to megestrol itself, has been extensively used as a pharmaceutical drug.
