Parsabiv (etelcalcetide) is a treatment for secondary hyperparathryoidism, or sHPT, in adult patients with chronic kidney disease on hemodialysis. Parsabiv® lowers the PTH, phosphorus, and calcium levels in your blood

Parsabiv acts on your parathyroid glands and causes them to release less parathyroid hormone (PTH). When your PTH goes down, your bones release less phosphorus and calcium.
