Platelet glycoprotein (GP) IIb/IIIa inhibitors prevent fibrinogen binding and platelet aggregation. They decrease ischemic complications associated with non-ST segment elevation acute coronary syndromes and percutaneous coronary intervention. Meta-analyses of 6 randomized trials of parenteral GP IIb/IIIa inhibitors in patients with acute coronary syndromes suggest a significant reduction in death and myocardial infarction in high risk patients. These include patients undergoing early percutaneous coronary intervention or those with high TIMI risk score, elevated troponin values, or diabetes mellitus. Despite guideline recommendations supporting therapy for these indications, only a minority of appropriate candidates are being treated. The risk of major bleeding is small; thrombocytopenia can result from abciximab therapy. Optimal dosing strategies continue to evolve.
