[Advances in the treatment of postmenopausal osteoporosis].
During the last decade, several medications have been registered and marketed in osteoporosis. They have demonstrated their anti-fracture efficacy. Subsequently, the clinical management of osteoporosis becomes more sophisticated and complex. Bisphosphonates (alendronate, risedronate, ibandronate) have demonstrated their efficacy on the axial and appendicular skeleton. On scientific grounds, it seems difficult to distinguish between them, in terms of efficacy and/or safety. A special interest should be focused on the optimisation of patients' adherence, which remains poor with the daily and weekly formulations. Raloxifene, a selective estrogen receptor modulator, has shown anti-fracture efficacy at the level of the lumbar spine and, also, exerts collateral benefits on the breast. The peptides from the parathyroid hormone family are stimulators of bone formation. They showed anti-fracture efficacy at the axial and appendicular skeleton. Due to their prohibitive cost, their use should be restricted to patients with severe osteoporosis. Strontium ranelate, with its unique mode of action combining inhibition of bone resorption and stimulation of bone formation, is characterized by a wide scatter of activity, both in terms of skeletal sites positively affected and of patients experiencing benefits of its administration. Currently, it is the only drug which has shown an extensive anti-fracture efficacy in elderly subjects over 80 years old.
