Effects of GP IIb/IIIa inhibitors on vascular inflammation, coronary microcirculation, and platelet function
1Heart Center of Greater Cincinnati, Cincinnati, Ohio, USA.
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.

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000 platelets, with...
