Lilopristone (INN) (developmental code names ZK-98734, ZK-734) is a synthetic, steroidal antiprogestogen with additional antiglucocorticoid activity which was developed by Schering and was patented in 1985.[1][2][3][4] It is described as an abortifacient and endometrial contraceptive.[1][4][5] The drug differs from mifepristone only in the structure of its C17α side chain, and is said to have much reduced antiglucocorticoid activity in comparison.[6]
