Norethindrone Acetate is completely and rapidly deacetylated to norethindrone (NET) after oral administration, and the disposition of Norethindrone Acetate is indistinguishable from that of orally administered norethindrone. Norethindrone Acetate is rapidly absorbed from Norethindrone Acetate tablets, with maximum plasma concentration of norethindrone generally occurring at about 2 hours post-dose.

Norethindrone Acetate is used to treat women with abnormal bleeding from the uterus.
Norethindrone Acetate 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, Norethindrone Acetate is used to treat a condition (子宮内膜症) in which tissue that normally lines the inside of the uterus is found outside the uterus in theabdomen/pelvic area, causing painful/irregular periods.
Norethindrone Acetate 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.
