Bazedoxifene, used as bazedoxifene acetate, is a medication for bone problems and possibly (pending more study) for cancer.[2] It is a third-generation selective estrogen receptor modulator (SERM).[3] Since late 2013 it has had U.S. FDA approval for bazedoxifene as part of the combination drug Duavee in the prevention (not treatment) of postmenopausal osteoporosis. It is also being studied for possible treatment of breast cancer and pancreatic cancer.[4]

Effect: + = Estrogenic / agonistic. ± = Mixed or neutral. – = Antiestrogenic / antagonistic. Note: SERMs generally increase gonadotropin levels in hypogonadal and eugonadal men as well as premenopausal women (antiestrogenic) but decrease gonadotropin levels in postmenopausal women (estrogenic).
