NCI: A drug that is used to treat hypercalcemia (too much calcium in the blood) and cancer that has spread to the bones. It belongs to the family of drugs called bisphosphonates.,NCI: A drug that is used to treat hypercalcemia (too much calcium in the blood) and cancer that has spread to the bones. It belongs to the family of drugs called bisphosphonates.,NCI: An amino- bisphosphonate with anti-resorptive and anti-hypercalcemic activities. Pamidronic acid binds to and adsorbs onto hydroxyapatite crystals in the bone matrix, thereby preventing osteoclast resorption. This agent also binds to and inhibits farnesyl pyrophosphate synthase, an enzyme that plays an important role in the mevalonate pathway. This inhibits the formation of isoprenoid metabolites that are substrates for protein prenylation. This prevents farnesylation and geranylgeranylation of proteins essential for osteoclast function, leading to the induction of apoptosis of osteoclasts. By preventing osteoclast-mediated bone resorption, pamidronic a
