Preventing fractures in postmenopausal women with osteoporosis. A review of recent controlled trials of antiresorptive agents.
The evidence from randomised, controlled trials of the ability of antiresorptive treatments to reduce the risk of fractures in postmenopausal women with osteoporosis is reviewed and summarised. The aminobisphosphonates, alendronic acid and risedronic acid, and the selective estrogen receptor modulator raloxifene have all been shown to reduce the incidence of radiographic vertebral fractures. Only alendronic acid and risedronic acid have been shown to reduce the incidence of non-spine fractures in women with postmenopausal osteoporosis. There is evidence of antifracture efficacy for calcium plus vitamin D, primarily in a nursing home setting or in people with low intakes of these nutrients. Furthermore, since both the placebo and active treatment groups received calcium and vitamin D in most controlled trials of antiresorptive agents, it appears that the other agents provide benefits beyond those of calcium and vitamin D alone. There is insufficient published evidence from randomised controlled trials to convincingly support the antifracture efficacy of other agents, including calcitonin, estrogen and etidronic acid, at this time. Data from observational studies suggest, however, that estrogen and etidronic acid may have antifracture efficacy in this population.[1]References
