Action

Disodium pamidronate inhibits osteoclasts, specific cells responsible for destruction of bone. Osteoclast precursors enter the bone from the bloodstream, and they eventually mature to become osteoclasts. In certain conditions, mature osteoclasts are responsible for destruction of bone and release of calcium into the bloodstream. Pamisol suppresses the migration of osteoclast precursors into bone, thereby preventing bone destruction and increased calcium levels.
