Alendronic Acid Tablet*70mg*Alendronic acid is an aminobisphosphonate which inhibits the activity on osteoclasts or osteoclast precursors, thus decreasing the rate of bone resorption leading to an indirect increase in bone mineral density. Its mechanism of action in Paget’s disease is characterised by inhibition of resorption leading to an indirect decrease in bone formation but the newly formed bone has a more normal structure.(FOROSA)*2
