Bazedoxifene
Bazedoxifene
Chemical compound
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).

The drug is a member of the 2-phenylindole group of SERMs, along with zindoxifene and pipendoxifene.[6]
Development
Bazedoxifene was developed by Pfizer following the completion of their takeover of Wyeth Pharmaceuticals. It is the result of an exclusive research collaboration between Wyeth Pharmaceuticals and Ligand Pharmaceuticals.[citation needed]
Approval
The drug was approved in the European Union by the European Medicines Agency on April 27, 2009.[7]
On October 3, 2013, the FDA approved the combination product of bazedoxifene 20 mg with 0.45 mg Premarin (conjugated estrogens) for the treatment of menopausal osteoporosis and the treatment of moderate to severe hot flushes. This is the first approved menopausal hormone therapy product that contains a SERM (bazedoxifene) and an estrogen.[citation needed]
Brand names
Bazedoxifene is marketed alone under the brand names Conbriza and Viviant and in combination with conjugated estrogens under the brand names Duavee and Duavive.[5]
