Lasofoxifene is an active component of Fablyn. Fablyn is used for the treatment of osteoporosis in postmenopausal women. Lasofoxifene is a nonsteroidal selective estrogen receptor modulator. Lasofoxifene has no effect on CYP2E1- or CYP2D6-mediated drug metabolism and should not affect drugs metabolized by other cytochrome P450 isoenzymes. Common adverse reactions considered to be related to Fablyn therapy were muscle spasms, hot flush and vaginal discharge. Lasofoxifene approved in the EU in 2009 is now withdrawn from use in the European Union.
