Calcitonin in hypercalcemia is used primarily for which reason?

Explanation:
Calcitonin lowers calcium primarily by inhibiting osteoclast-mediated bone resorption, which rapidly reduces the release of calcium from bone and brings down serum calcium quickly in hypercalcemia. There’s also a minor effect of increasing calcium excretion by the kidneys, but the main clinical action is on bone resorption. It doesn’t promote bone formation, nor is it produced by the thyroid to be “stimulated” in response to treatment. In practice, it provides fast but modest calcium lowering and is often used while slower, longer-acting therapies like bisphosphonates take effect.
