Post-Menopausal Osteoporosis
Conditions
Keywords
Osteoporosis, Bone Mineral density, fragility fractures, zoledronic acid., Treatment
Brief summary
The study will assess the real life effectiveness of zoledronic acid in the management of patients with osteoporosis over 4 years of treatment. Zoledronic acid will be compared to oral bisphosphonates (OBP) with respect to the change in Bone Mineral Density (BMD) and incidence of fractures.
