Calcitonin, a medication to reverse bone loss

Calcitonin (kal-si-TOE-nin) sold under the brand names Calcimar, Cibacalcin, Calsynar, Miacalcin, Osteocalcin and Salmonine is a medication prescribed for the treatment of Osteoporosis. The medication is also used to treat bone loss from hypercalcaemia, Paget's disease and bone metastases.

If you were prescribed a bisphosphonate medications such as: ActonelBoniva , Fosamax  and you found that the prescription drug irritated your digestive tract, you may find Calcitonin  a good alternative.

There are two two main forms: Calcitonin-Human (kal-si-TOE-nin HYOO-man) which is injectable and and Calcitonin-Salmon (kal-si-TOE-ninSAM-en) which comes both in an injectable form and as a nasal spray. (Some people prefer the spray form.)

Calcitonin was first purified in 1962 by DH Copp and B. Cheney. These researchers published a report of their work in Nature. ( Copp DH, Cheney B. Calcitonin-a hormone from the parathyroid which lowers the calcium-level of the blood. Nature 1962;193:381-2.)

Frequently asked questions about Calcitonin:

  1. Exactly what IS this drug?
    According to the Wikipeida Encyclopedia,"Calcitonin is a a 32 amino acid polypeptide hormone that is produced in humans primarily by the C cells of the thyroid". 
  2. What does the Calcitonin do?
    This  hormonal drug affects your calcium and phosphorus metabolism. The main effect is on bone.                                                                                              Your bones are constantly being remodeled. Old bone is removed by your osteoclasts cells and new bone is made by your osteoblasts cells. Calcitonin inhibits the activity of osteoclasts AND it promotes bone formation by osteoblasts. It also decreases mineral release and matrix or collagen breakdown in bone. As a result Calcitonin, has the effect of increasing bone density and that is why it is prescribed in the treatment of Osteoporosis.
