Eptifibatide, marketed as Integrilin, is a platelet aggregation inhibitor drug. It is administered intravenously and can act to decrease platelet aggregation for up to two days after administration. Eptifibatide is a small peptide derived from rattlesnake venom that targets glycoprotein IIb/IIIa receptors on the outer membrane of platelets. In the blood vessel, eptifibatide causes a conformational change in the integrins on the surface of activated platelets. This prevents the binding of fibrinogen to these integrins, which in turn prevents the platelets from being held together by these fibrinogen fibres. The conformational change also prevents the binding of the von Willebrand factor to the platelets, which also prevents aggregation and adhesion.
