Brief summary

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.
