Primary Outcome Measures :
  1. Pharmacokinetic measures of blood levels of endogenous estrogen hormones, conjugated estrogens and bazedoxifene.

Secondary Outcome Measures :
  1. Safety will be evaluated from reported signs and symptoms, scheduled physical examinations, gynecologic examinations, vital sign measurements, 12-lead ECG and clinical laboratory test results.
