Eptifibatide (Integrilin) vs Icatibant (Firazyr)

An educational, source-based comparison of Eptifibatide (Integrilin) and Icatibant (Firazyr) — 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.

Bradykinin Antagonist · Immunology
Icatibant (Firazyr)

Bradykinin B2 receptor antagonist for hereditary angioedema attacks.

Mechanism

Synthetic decapeptide that competitively blocks the bradykinin B2 receptor, halting the vascular leak that drives HAE swelling attacks.

Research areas
  • Hereditary angioedema (acute attacks)
Considerations
  • FDA-approved.
  • Injection-site reactions very common.
