Study Evaluating Premarin and Bazedoxifene Potential Interaction

February 11, 2009 updated by: Wyeth is now a wholly owned subsidiary of Pfizer

An Open-Label, Single/Multiple Dose Non-Randomized, 3-Period, Crossover Study To Determine The Potential Drug Interaction Of Conjugated Estrogens (CE) On Bazedoxifene In Healthy Postmenopausal Women.

The purpose of this study is to evaluate the pharmacokinetics (absorption, distribution, breakdown and elimination in the body) of a single dose of bazedoxifene (BZA) 20 mg tablet when administered together with multiple doses of Premarin (conjugated estrogens or CE) to healthy postmenopausal women.

Information will also be obtained regarding the safety and tolerability of this combination in healthy, postmenopausal women.
