[Diphosphonates--pharmacology and clinical use].
Based upon recent research, bisphosphonates have now attained a ranking as the first alternative to oestrogen replacement therapy in women with postmenopausal osteoporosis. The efficacy of these drugs has been clearly documented in recent years, particularly as a result of extensive clinical trials with alendronate. The studies have also confirmed the favourable risk/benefit ratio. The specific affinity of bisphosphonates for bone tissue has been recognized for many years, and explains the diagnostic use of radio-labelled species in skeleton scintigraphy. Bisphosphonates deposited in bone tissue reverse the osteoporotic process by inhibiting osteoclastic bone resorption. This mechanism also explains their role as the treatment of choice in patients with Paget's disease and cancer induced hypercalcaemia. In addition, the same drugs are useful adjuvants in the treatment of patients with multiple myeloma or bone metastases to lessen the pain and risk of fracture. A possible role of bisphosphonates in the management of cancer patients without detectable bone metastases or patients with rheumatoid arthritis has been discussed, but further research is needed in these areas.
