Estradiol acetate (INN, USAN, BAN; brand names Femtrace, Femring, Menoring) is a synthetic ester, specifically the 3-O-acetyl ester, of the natural estrogen, estradiol. It is relatively recent to the market, having been first approved in a vaginal ring formulation as Menoring in the United Kingdom in 2001,[1] followed by another vaginal ring formulation as Femring in the United States in 2003,[2] and finally as an oral preparation as Femtrace in the United States in 2004.[2] It is used as a form of hormone replacement therapy to treat and prevent symptoms of menopause such as osteoporosis in postmenopausal women.[1][3][4][5]
