Calcitonin for the treatment and prevention of corticosteroid-induced osteoporosis.

Corticosteroid-induced osteoporosis is a cause of morbidity in patients with chronic obstructive lung disease, asthma, and rheumatologic disorders. Corticosteroid treatment causes bone loss by a variety of complex mechanisms. It has been shown that bone mineral loss at the hip averages 14% in the first year after starting corticosteroid therapy.
