This is a combination medication consisting of estradiol and norethindrone acetate. Estradiol belongs to the estrogen class of medications while norethindrone acetate is classified as a progestin. The medication is indicated for oral hormone replacement therapy in women experiencing menopausal and vaginal symptoms. It is formulated for women who have not undergone a hysterectomy, as progestin is necessary in conjunction with estrogen to prevent complications such as endometrial hyperplasia which may arise from using estrogen alone.
