Document Details : Title: Management of primary osteoporosis Author(s): BODY JJ Journal: Acta Clinica Belgica Volume: 57 Issue: 5 Date: 2002 Pages: 277-283 DOI: 10.2143/ACB.57.5.1002816 Abstract : Although there is a great need for better therapeutic approaches to the patient who presents with a fracture, osteoporotic fractures will remain a condition that is more amenable to prevention than treatment. Hormone replacement therapy (HRT) is still considered by many the mainstay for the prevention and the treatment of posrmenopausal osteoporosis. However, there are several controversies regarding HRT, especially the duration of treatment and the risks/benefits ratio. Recent studies have challenged the assumption that HRT conveys real long-term beneficial effects. Raloxifene or other “selective estrogen receptor modulators” (SERMs) should progressively replace HRT in elderly women. Bisphosphonates have demonstrated a clearcut efficacy in the treatment of osteoporosis. Alendronate and risedronate have been the most extensively studied bisphosphonates under randomized controlled trials conditions. Both agents can reduce the risk of vertebral and hip fractures by one-fourth to one-half. However, oral bisphosphonates are not without gastro-intestinal toxicity and strict adherence to constraining therapeutic schemes is mandatory. Intermittent treatments are alredy in use. Weekly alendronate is as efficient as daily therapy and improves treatment compliance. Newer more potent bisphosphonates, such as oral ibandronate or intravenous zoledronic acid, will allow much less frequent administration. The anti-fracture efficacy of yearly zoledronic acid infusions is thus currently tested. On the other hand, bone-forming agents, such as daily subcutaneous injections of teriparatide (rhPTH 1-34) offer exciting perspectives for the treatment of severe osteoporosis despite the complexity of such therapy. |
