Theropeutic Class
Hormone in bone formation by Inhibiting bone resorption
Pharmacology
Calcitonin is a polypeptide hormone produced by the ultimobranchial gland in non-mammalian vertebrates or by the mammalian thyroid parafollicular cells. It inhibits osteoclastic bone resorption and reduces bone turnover. It decreases tubular reabsorption and promotes renal excretion of Ca, Cl, Na, Mg, K and phosphate.
