Role of Calcitonin and Strontium Ranelate in Osteoporosis.

Abstract

Both Strontium Ranelate (SR) and Calcitonin (CT) can be used to treat osteoporosis. Calcitonin was actually one of the very initial medicines used to treat osteoporosis, especially in postmenopausal cases. However, the fracture prevention effect of Calcitonin is only proven to be in vertebrae and that too with nasal route only. When comparing Calcitonin with other conventional medications in treating osteoporosis, Calcitonin has got no additional advantages. Strontium Ranelate has got double effect, i.e., less bone resorption and more bone formation. Therefore, it can lead to an increase in bone mass significantly. Strontium Ranelate has been proven to decrease the risk of non-vertebral fractures as well as vertebral fractures. Both Calcitonin and Strontium Ranelate are used only as a second-line therapy for the treatment of osteoporosis and not as first-line therapy, mainly because of their safety concern and also because they do not provide any advantages compared to other therapy for the treatment of osteoporosis.
