Enfuvirtide (Fuzeon) vs Eptifibatide (Integrilin)

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

Fusion Inhibitor · Antiviral
Enfuvirtide (Fuzeon)

First-in-class HIV fusion inhibitor peptide.

Mechanism

36-amino-acid peptide that binds the gp41 subunit of HIV-1 envelope, blocking the conformational change required for viral-host membrane fusion and cell entry.

Research areas
  • Treatment-experienced HIV-1 infection
Considerations
  • FDA-approved.
  • Injection-site reactions nearly universal.

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.
