Osteoporosis
Prevention of osteoporosis in postmenopausal women. Risk factors for postmenopausal osteoporosis and related fractures include early menopause, advanced age, low bone mineral density (BMD), low body mass index (BMI), previous fracture or family history of fracture/osteoporosis, excessive alcohol intake, smoking, inadequate physical activity, low calcium and vitamin D intake, certain drugs (e.g., glucocorticoids), and medical conditions or diseases (e.g., rheumatoid arthritis, diabetes mellitus, Cushing syndrome, hyperparathyroidism). 
Treatment of osteoporosis in postmenopausal women.  
In addition to adequate intake of calcium/vitamin D and other lifestyle modifications (e.g., exercise, avoidance of excessive alcohol and tobacco use), experts recommend that pharmacologic therapy for osteoporosis be considered in postmenopausal women with previous hip or vertebral fractures or low BMD; pharmacologic therapy also may be considered in postmenopausal women with low bone mass, although there is less evidence supporting overall fracture risk reduction in such patients. 
Use of a drug with proven efficacy in reducing fracture risk is recommended; bisphosphonates (e.g., alendronate, risedronate, zoledronic acid, ibandronate) are recommended as one of several first-line drugs. 
Individualize choice of therapy based on potential benefits (with respect to fracture risk reduction) and adverse effects of therapy, patient preferences, comorbidities, and risk factors. 
Glucocorticoid-induced Osteoporosis
Also has been used in the management of glucocorticoid-induced osteoporosis†. 
American College of Rheumatology (ACR) recommends optimizing calcium and vitamin D intake and lifestyle modifications (e.g., diet, smoking cessation, weight-bearing or resistance-training exercise) in all patients receiving long-term glucocorticoid therapy; in addition, pharmacologic therapy with an oral bisphosphonate is recommended in patients who are considered to be at moderate-to-high risk of fracture. Oral bisphosphonates generally are preferred because of their demonstrated antifracture benefits, safety, and low cost.
