Study to Evaluate Equivalence of Estradiol Vaginal Cream 0.01% to Estrace® Cream 0.01% in Atrophic Vaginitis

Systemic (oral or transdermal patch administration) estrogen therapies have been shown to effectively treat symptoms of atrophic vaginitis but bear undesirable side effects including increased risk of heart attacks, stroke, endometrial cancer, and breast cancer. Topical therapies (creams and transvaginal delivery systems) provide low doses of estrogen to the vaginal mucosa to provide local relief for the symptoms of atrophic vaginitis, while reducing the unwanted side effects associated with systemic delivery systems. Low dose, topical estrogen therapy is considered most appropriate and convenient for the treatment of vaginal symptoms associated with menopause, particularly when other symptoms including bone loss or vasomotor dysfunction do not need to be targeted.
