Bone Turnover Markers and Treatment Efficacy in Postmenopausal Osteoporosis

This study investigates the use of blood tests known as Bone Turnover Markers (BTMs) to quickly monitor the effectiveness of osteoporosis treatment in postmenopausal women. Osteoporosis, which weakens bones and increases fracture risk, is typically monitored using a DEXA scan to measure bone density (BMD), but this method changes slowly. BTMs may show a response to medication within just 3 to 6 months. In this randomized controlled trial, 40 postmenopausal women with osteoporosis will be assigned to receive either antiresorptive drugs (which slow bone loss) or anabolic drugs (which build new bone), along with calcium and vitamin D. The study will compare how these treatments affect BTMs and BMD over six months to determine if BTMs can serve as an early and reliable indicator of treatment success, which could be particularly useful in regions like Pakistan where access to repeated DEXA scans is limited.
