The effects of the diphosphonates etidronate and clodronate were studied in 144 patients with Paget's disease. All five programmes of treatment tested induced a similar suppression of disease activity as judged by serum alkaline phosphatase concentrations, but the proportion of patients responding and the duration of responses differed significantly between programmes. The proportion responding to etidronate 5-10 mg/kg/day for six months was less than for other regimens, and the most sustained response was after treatment with clodronate 1600 mg daily for six months. More complete biochemical suppression was associated with the more prolonged responses irrespective of the regimen used.

UI MeSH Term Description Entries
D010001 Osteitis Deformans A disease marked by repeated episodes of increased bone resorption followed by excessive attempts at repair, resulting in weakened, deformed bones of increased mass. The resultant architecture of the bone assumes a mosaic pattern in which the fibers take on a haphazard pattern instead of the normal parallel symmetry.

D004164 Diphosphonates Organic compounds which contain P-C-P bonds, where P stands for phosphonates or phosphonic acids. These compounds affect calcium metabolism. They inhibit ectopic calcification and slow down bone resorption and bone turnover. Technetium complexes of diphosphonates have been used successfully as bone scanning agents.
