Eptifibatide Side Effects: Safety Signals and Warnings
Eptifibatide safety concerns are compound-specific. The main listed side effects are Bleeding (major and minor), Thrombocytopenia, and Hypotension. The main warning signals are Contraindicated with active internal bleeding or recent surgery, Severe thrombocytopenia (<100,000/mm3) - discontinue immediately, and Renal dose adjustment required (CrCl <50 mL/min).
Direct Answer
Eptifibatide (Integrilin) is FDA-approved for acute coronary syndrome and PCI with Phase 3 evidence from the PURSUIT and ESPRIT trials demonstrating reduced composite ischemic endpoints. As a cyclic RGD peptide GP IIb/IIIa inhibitor, it provides potent antiplatelet effect during percutaneous intervention. A well-established cardiovascular drug with a clear, validated indication.
