Detailed information:

Norethisterone acetate (NETA) (INN, BAN), also known as norethindrone acetate (USAN), sold under brand names including Primolut-Nor (major), Aygestin (US), Gestakadin, Milligynon, Monogest, Norlutate (US, CA), Primolut N, SH-420 (UK), Sovel, Styptin, and others, is a steroidal progestin of the 19-nortestosterone group with additional weak androgenic and estrogenic activity that is used orally as a hormonal contraceptive, in the treatment of gynecological disorders such as abnormal uterine bleeding, and as a component of hormone replacement therapy for menopause. It is the 17β-acetate ester of norethisterone, and acts as a prodrug to norethisterone in the body.

This medication is used to treat women with abnormal bleeding from the uterus. It is also used to treat women who have stopped having menstrual periods for several months (amenorrhea) but who are not pregnant or going through menopause. In addition, this medication is used to treat a condition (endometriosis) in which tissue that normally lines the inside of the uterus is found outside the uterus in the abdomen/pelvic area, causing painful/irregular periods. Norethindrone is a type of female hormone (progestin). It is like the hormone progesterone that your body makes naturally. This medication works by stopping the normal growth of the uterus lining during the menstrual cycle and signaling hormone changes in the uterus to restore normal menstrual periods.
