Cinacalcet is a calcimimetic agent used primarily for the treatment of secondary hyperparathyroidism in patients with chronic kidney disease on dialysis, and for hypercalcemia in patients with parathyroid carcinoma. It is approved and widely used today as an oral medication that acts by increasing the sensitivity of the calcium-sensing receptor on the parathyroid gland to extracellular calcium.
