Indications
• High calcium levels in the blood • Hyperparathyroidism
Mechanism of action
Cinacalcet is a calcimimetic agent. It lowers parathyroid hormone (PTH) secretion by increasing the sensitivity of the calcium-sensing receptor of the parathyroid gland to activation by extracellular calcium. PTH reduction leads to concomitant decrease in serum calcium and phosphorus concentrations.
