This trial is conducted in Europe. The aim of this trial is to to evaluate the extent of systemic absorption of estradiol during treatment with two different doses of estradiol in postmenopausal women with atrophic vaginitis.

Condition Intervention Phase
Menopause Postmenopausal Vaginal Atrophy Drug: estradiol, 10 mcg Drug: estradiol, 25 mcg Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Pharmacokinetic Randomized Study With a Parallel Group Design to Assess the Extent of Systemic Absorption of Estradiol During Treatment With a 10 µg or 25 µg Estradiol Vaginal Tablet Administered Once Daily for 2 Weeks Followed by 10 Weeks of Twice-Weekly Maintenance Therapy in Postmenopausal Women With Atrophic Vaginitis
