What type of fractures does raloxifene primarily help to prevent?

Raloxifene is primarily used to prevent vertebral fractures, particularly in postmenopausal women who have osteoporosis or are at risk for it. This medication is a selective estrogen receptor modulator (SERM), which mimics estrogen's beneficial effects on bone density without some of the risks associated with estrogen therapy. By increasing bone mineral density and reducing the turnover of bone, raloxifene effectively reduces the occurrence of vertebral fractures.

While it may have some protective effects on other types of fractures, the emphasis in clinical studies and guidelines focuses on its effectiveness in preventing vertebral fractures specifically. Other types of fractures, such as hip or distal radius fractures, are typically addressed through different therapies or medications.
