Quingestanol acetate (INN, USAN) (brand names Demovis, Pilomin, Riglovis, Unovis), also known as norethisterone acetate 3-cyclopentyl enol ether, is a progestin of the 19-nortestosterone group with additional weak androgenic and estrogenic activity which is used as an oral, once-a-month, or postcoital hormonal contraceptive.[1][2][3][4] It is a prodrug of norethisterone, with both quingestanol and norethisterone acetate serving as intermediates in the transformation.[5][6] The drug was patented in 1963[7] and marketed in Italy in 1972.[8][9]
