Estradiol/Norethindrone Acetate Tablets, 1/0.5 mg Under Fasting Conditions
November 22, 2010 updated by: Teva Pharmaceuticals USA
A Two-Way Crossover, Open-Label, Single-Dose, Fasting, Bioequivalence Study of Estradiol/Norethindrone Acetate Tablets, 1 mg/0.5 mg Versus Activella® (1 mg Estradiol/0.5 mg Norethindrone Acetate) Tablets in Normal, Healthy, Post-Menopausal Female Subjects
The objective of this study was to determine and compare the rate and extent of absorption of norethindrone and unconjugated estradiol from a test formulation of Estradiol/Norethindrone Acetate Tablets, 1 mg/0.5 mg versus the reference Activella® (1 mg estradiol/0.5 mg norethindrone acetate) Tablets under fasting conditions.
