Etelcalcetide

Published: July 26, 2026Updated: July 26, 2026

Etelcalcetide is a calcimimetic agent used to treat secondary hyperparathyroidism in adults with chronic kidney disease who are undergoing hemodialysis. It works by binding to and activating the calcium-sensing receptor on parathyroid cells, which reduces the secretion of parathyroid hormone (PTH). This medication is administered intravenously at the end of dialysis sessions.

Quick summary

Etelcalcetide is a calcimimetic that lowers parathyroid hormone levels in dialysis patients with secondary hyperparathyroidism.

Mechanism of action

Value:Calcium-sensing receptor agonist

Primary pharmacological mechanism

Treatment of secondary hyperparathyroidism in adult patients with chronic kidney disease (CKD) on hemodialysis.

Etelcalcetide allosterically modulates the calcium-sensing receptor (CaSR) by binding to it and enhancing receptor activation by extracellular calcium, leading to decreased PTH secretion from parathyroid chief cells.

Administered intravenously at the end of dialysis sessions. May cause hypocalcemia; regular serum calcium monitoring is required. Contraindicated in patients with hypocalcemia. Common side effects may include muscle spasms, nausea, and paresthesia.
