Eptifibatide (Integrilin) vs Etelcalcetide (Parsabiv)

An educational, source-based comparison of Eptifibatide (Integrilin) and Etelcalcetide (Parsabiv) — how each peptide works, what it's researched for, and what to know before going deeper.

Antiplatelet · Cardiology
Eptifibatide (Integrilin)

GP IIb/IIIa inhibitor cyclic peptide for ACS and PCI.

Mechanism

Cyclic heptapeptide derived from rattlesnake venom that reversibly blocks platelet glycoprotein IIb/IIIa receptors, preventing fibrinogen binding and platelet aggregation.

Research areas
  • Acute coronary syndromes
  • PCI
Considerations
  • FDA-approved.
  • Bleeding risk; renal adjustment required.

Calcium-Sensing Receptor Agonist · Endocrine
Etelcalcetide (Parsabiv)

Calcimimetic peptide for secondary hyperparathyroidism on hemodialysis.

Mechanism

Synthetic D-amino-acid peptide that binds the calcium-sensing receptor on parathyroid chief cells, increasing its sensitivity to extracellular calcium and lowering PTH secretion.

Research areas
  • Secondary hyperparathyroidism in adults on chronic hemodialysis
Considerations
  • FDA-approved.
  • Hypocalcemia common; monitor calcium and avoid in low corrected calcium.
