What is Parsabiv (etelcalcetide), and what is it used for?
Parsabiv is the brand name for etelcalcetide, a calcimimetic medicine used in adults with secondary hyperparathyroidism associated with chronic kidney disease on dialysis. It helps lower parathyroid hormone (PTH) levels by increasing the sensitivity of the calcium-sensing receptor in the parathyroid gland.[1]
How does etelcalcetide work compared with other “calcimimetic” drugs?
Etelcalcetide is a calcimimetic like cinacalcet, but it is given as an IV injection after dialysis rather than as an oral tablet.[1] By activating calcium-sensing receptors, it reduces PTH secretion; the key practical differences for patients are dosing route and administration schedule rather than the general mechanism.[1]
How is Parsabiv typically dosed?
Parsabiv (etelcalcetide) is administered by healthcare professionals as an injection in a dialysis setting (after dialysis). The dosing is adjusted to keep PTH in a target range; dose changes are based on lab monitoring and clinical response.[1]
What are the main safety and side-effect concerns patients ask about?
Calcimimetics can lower calcium, so hypocalcemia is a major safety concern with etelcalcetide therapy. Patients and clinicians typically monitor blood calcium and adjust treatment to manage low calcium levels.[1]
How does Parsabiv compare with cinacalcet (Sensipar/Mimpara)?
Both drugs are calcimimetics used to treat secondary hyperparathyroidism in dialysis patients, and both act through calcium-sensing receptor activation to reduce PTH.[1] The practical difference most patients notice is administration: etelcalcetide is given as an injection in the dialysis clinic rather than taken by mouth.[1]
