Mechanism of action

Raloxifene acts as a selective estrogen receptor modulator (SERM) that mimics estrogen effects on bone tissue, reducing bone turnover and resorption. Alendronate is a bisphosphonate that binds to hydroxyapatite in bone and inhibits osteoclast function, further suppressing bone resorption. Together, these complementary mechanisms work synergistically to increase bone mineral density and reduce fracture risk in postmenopausal women.
