Etelcalcetide is a synthetic peptide calcimimetic agent used for the treatment of secondary hyperparathyroidism in adult patients with chronic kidney disease (CKD) on hemodialysis. It acts as an agonist of the calcium-sensing receptor on parathyroid cells, thereby lowering parathyroid hormone (PTH) levels. Etelcalcetide is approved and currently used clinically.
Pharmacokinetics
Pharmacokinetic parameters reported for adult patients with end-stage renal disease on hemodialysis, following intravenous administration.
