BMP pathway→osteoblast differentiation→bone mineral density increase
Statins, particularly lipophilic simvastatin, promote osteoblast differentiation and mineralization through bone morphogenetic protein pathways, potentially preventing osteoporosis and reducing fracture risk. Evidence includes observational studies showing reduced osteoporosis rates and experimental mechanistic data. However, results are inconsistent and no RCT has established clinical efficacy for osteoporosis treatment.
