title: Platelet glycoprotein IIb/IIIa inhibitor use during percutaneous coronary intervention: IIb or Not IIb, what is the question?
abstract: Over the past decade, numerous placebo-controlled randomized clinical trials have documented robust clinical benefits of intravenous platelet glycoprotein (GP) IIb/IIIa inhibitors in patients undergoing percutaneous coronary intervention (PCI). This evidence has led to U.S. Food and Drug Administration approval and indication for use of two GP IIb/IIIa inhibitors at the time of PCI, namely, the chimeric monoclonal antibody fragment abciximab (ReoPro, Centocor, Inc. and Eli Lilly & Company) and the cyclic heptapeptide small molecule eptifibatide (Integrilin, COR Therapeutics and Key Pharmaceuticals). Currently, another small molecule GP IIb/IIIa inhibitor, tirofiban (Aggrastat, Merck & Company), which (similar to eptifibatide) is approved for the medical therapy of patients with non-ST segment elevation acute coronary syndromes (ACS), has not received indication for use in the PCI setting. Although the clinical benefits of both abciximab and eptifibatide administered at the time of PCI have been proven in randomized clinical trials, only abciximab has demonstrated a late survival advantage in patients following PCI. Evidence in support of the presence, magnitude and possible mechanisms for abciximab survival advantage is herein reviewed.
