Glycoprotein (GP) IIb/IIIa receptor antagonists inhibit the binding of ligands to activated platelet GP IIb/IIIa receptors and, therefore, prevent the formation of platelet thrombi. Additional antithrombin therapy should be given in connection with GP IIb/IIIa administration. Eptifibatide is a small heptapeptide, which is highly selective and rapidly dissociates from its receptor after cessation of therapy. In clinical trials (IMPACT-II and ESPRIT) concomitant administration of eptifibatide to patients undergoing percutaneous coronary intervention (PCI) reduced thrombotic complications. In the PURSUIT trial, in patients with non-ST-elevation acute coronary syndromes, eptifibatide, compared to placebo, significantly reduced the primary endpoint of death and nonfatal myocardial infarction at 30 days. In patients with STEMI eptifibatide has been studied as an adjunct to fibrinolysis and primary PCI; it improved epicardial flow and tissue reperfusion. Current studies are evaluating eptifibatide as upstream therapy in high-risk patients with NSTE-ACS, in the EARLY-ACS and in comparison with abciximab in patients with primary PCI in the EVA-AMI trial.
