Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Bazedoxifene (BZA) 20 mg tablet is an investigational medication (not approved by FDA) which is being studied for possible prevention and treatment of postmenopausal osteoporosis.

PREMARIN® (conjugated estrogens \[CE\]) is approved by FDA to treat moderate to severe symptoms of menopause (i.e., hot flashes, and/or vulvar and vaginal atrophy) and for the prevention of postmenopausal osteoporosis.

The purpose of this study is to evaluate the pharmacokinetics (absorption, distribution, breakdown and elimination in the body) of a single dose of PREMARIN® when administered together with multiple doses of bazedoxifene (BZA) to healthy postmenopausal women.

Information will also be obtained regarding the safety and tolerability of the study medications when given together to healthy postmenopausal women.
