Calcitonin is a prescription drug approved by the Food and Drug Administration (FDA) to treat postmenopausal osteoporosis in women who have been postmenopausal for at least five years. Calcitonin may be indicated in cases where other treatments do not work or cannot be tolerated. Calcitonin is marketed under brand names including Fortical and Miacalcin.
Calcitonin is a synthetic version of a hormone secreted by the thyroid gland. Calcitonin is believed to work by reducing the activity of osteoclasts, the cells that break down bone.
