Bazedoxifene is used for the prevention and treatment of osteoporosis. After peroral application, bazedoxifene is metabolized by UDP-glucuronosyltransferases (UGTs) to bazedoxifene-4'-glucuronide (M4) and bazedoxifene-5-glucuronide (M5). It has already been shown that a relatively common UGT1A1*28 polymorphism can considerably affect raloxifene
