Eptifibatide (Integrilin) vs Ziconotide (Prialt)

An educational, source-based comparison of Eptifibatide (Integrilin) and Ziconotide (Prialt) — 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.

N-type Calcium Channel Blocker · Analgesic
Ziconotide (Prialt)

Synthetic ω-conopeptide for severe chronic pain via intrathecal infusion.

Mechanism

Synthetic version of ω-conotoxin MVIIA from cone snail Conus magus; selectively blocks N-type voltage-gated calcium channels on primary afferent nerve terminals in the spinal dorsal horn, inhibiting nociceptive neurotransmitter release.

Research areas
  • Severe chronic pain refractory to systemic analgesics, intrathecal morphine
Considerations
  • FDA-approved.
  • Black-box warning for severe psychiatric and neurologic effects.
  • Contraindicated in history of psychosis.
