Biochem/physiol Actions

Lasofoxifene is a third-generation selective estrogen receptor modulator (SERM).
Lasofoxifene possesses strong resistance to intestinal wall glucuronidation and thus promotes oral bioavailability. In postmenopausal women, it reduces bone resorption, bone loss and low density lipoprotein (LDL) cholesterol. Selective and regular dose of Lasofoxifene is known to reduce the risk of fractures, breast cancer, major coronary heart disease, and stroke.
