Overview of Etelcalcetide

• Etelcalcetide belongs to a group of medications called calcimimetics that imitates the action of calcium on tissues.

Why is Etelcalcetide Prescribed? (Indications)

• Etelcalcetide has been approved by US FDA on Feb.2017 for the treatment of secondary hyperparathyroidism (HPT) in adults who suffer chronic kidney disease and undergo hemodialysis.
• Secondary hyperparathyroidism is a condition in which the body produces the excess parathyroid hormone in response to a low level of calcium in the blood which is usually observed in chronic kidney disease patients.
• Etelcalcetide acts by activating the calcium-sensing receptor in the parathyroid gland and signals the body to produce less parathyroid hormone, thereby decreasing the level of calcium and phosphorus in the blood.
