Menopause Healthy Drug: 0.5 mg estradiol / 0.1 mg norethisterone acetate (NETA) Drug: 0.5 mg estradiol / 0.25 mg norethisterone acetate (NETA) Drug: 1.0 mg estradiol / 0.5 mg norethisterone acetate (NETA) Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Single Dose, Three-way, Cross-over, Relative Bioavailability Study With 3 Oral Formulations for Hormone Replacement Therapy in Postmenopausal Women: 0.5 mg Estradiol + 0.1 mg Norethisterone Acetate, 0.5 mg Estradiol + 0.25 mg Norethisterone Acetate, and 1.0 mg Estradiol + 0.5 mg Norethisterone Acetate
