BISPHOSPHONATES
The bisphosphonates are
analogues of pyrophosphate, with high affinity for bone, especially in areas of
increased bone turn over, where they are powerful inhibitors of bone
resorption. The bisphosphonates are
concentrated in areas of high bone turn over and are taken up by and inhibit
osteoclast action. The potency of the compounds
for inhibition of bone resorption varies a thousand fold, increasing in the
order of etidronate, tiludronate, pamidronate, alendronate, and risdronate. Pamidronate
is the only bisphosphanate currently approved for intravenous use in paget
disease
