Miacalcin is FDA-approved for treating Paget's disease of bone, hypercalcemia associated with malignancy, and postmenopausal osteoporosis. It may also be used off-label for other conditions involving abnormal bone metabolism.
Calcitonin salmon is a synthetic version of a hormone produced by the thyroid gland. It works by inhibiting osteoclast cells that break down bone tissue, thereby reducing bone resorption, decreasing bone turnover, and lowering elevated blood calcium levels.
Available as injection or nasal spray formulations. Common side effects include nausea, flushing, and nasal irritation (with spray). Should be used with adequate calcium and vitamin D supplementation. Long-term use may be associated with increased malignancy risk. Treatment for osteoporosis is generally recommended for limited duration due to potential reduced efficacy over time.
