Chlormadinone is a progestin which was never marketed.[1][2] An acylated derivative, chlormadinone acetate, is used clinically as a pharmaceutical drug.[1][2]

It was patented in 1958 and approved for medical use in 1963.[3] While chlormadinone is sometimes used as a synonym for chlormadinone acetate, what is almost always being referred to is chlormadinone acetate and not chlormadinone.
