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. The drug was approved in the European Union by the European Medicines Agency on April 27, 2009. 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.
