Delmadinone acetate (INN, USAN, BAN; sold under brand names including Delmate, Estrex, Tardak, Tardastren, Tardastrex, Vetadinon, and Zenadrex), sometimes abbreviated as DMA, is a steroidal progestin with antigonadotropic (and hence, antiandrogenic and antiestrogenic) properties which is used to treat androgen-associated conditions in veterinary medicine.[1][2][3] It must be used with care as it has the potential to cause adrenal insufficiency via inhibition of adrenocorticotropic hormone (ACTH) secretion from the pituitary gland.[4]


Delmadinone acetate is made by the SeO2 oxidation of Chlormadinone acetate.
