Etynodiol diacetate (INN) (sold as Continuin, Femulen, Luteonorm, Luto-Metrodiol, and Metrodiol), or ethynodiol diacetate (USAN, BAN), also known as norethindrol diacetate, is a steroidal progestin which is used as a hormonal contraceptive. Relative to other 19-nortestosterone derivatives, it has relatively little or no potency as an androgen, and, unlike most progestins but similarly to noretynodrel, also has some estrogenic effects.
