Calcitonin is used in clinical practice for which purpose?

• A. Calcitonin lowers serum calcium and bone resorption; used selectively for osteoporosis or certain calcium disorders and sometimes cancer-related pain.
• B. First-line therapy for hypercalcemia
• C. Primary treatment for osteoporosis
• D. Not used clinically

Answer: (C)

Calcitonin lowers serum calcium and inhibits osteoclast-mediated bone resorption. It is used selectively in osteoporosis or other calcium disorders and can provide relief for cancer-related bone pain. It is not the primary treatment for osteoporosis, because other agents (such as bisphosphonates or denosumab) offer greater and more durable fracture protection. In hypercalcemia, it can be used for rapid, short-term calcium reduction as part of initial management, but it is not a long-term solution.
