title: Effects of GP IIb/IIIa inhibitors on vascular inflammation, coronary microcirculation, and platelet function.
abstract: The platelet glycoprotein (GP) IIb/IIIa inhibitors differ markedly in their pharmacokinetics, pharmacodynamics, and differential receptor affinities. Abciximab and the small-molecule GP IIb/IIIa inhibitors (eptifibatide, tirofiban) have separate, distinct binding sites on the GP IIb/IIIa receptor complex. The affinity of abciximab for the platelet GP IIb/IIIa integrin receptor, together with non-platelet-receptor mediated effects achieved through its affinity for the aVb3 and CD11b/18 receptors, most likely contribute to the clinical benefit associated with the use of abciximab as adjunctive pharmacotherapy during primary percutaneous coronary intervention for the treatment of ST-elevation acute myocardial infarction.
