In a few short years, platelet glycoprotein IIb/IIIa receptor antagonists h
ave been developed from laboratory curiosities to critical treatment adjunc
ts to the successful performance of PCI. With more than 15 000 patients par
ticipating in trials of these agents during PCI, it is now clear that glyco
protein IIb/IIIa blockade reduces rates of adverse cardiovascular sequelae
after PCI. Abciximab is the most extensively studied agent to date, but tri
als of other antagonists, particularly eptifibatide and tirofiban, support
the utility of this class of therapeutic agents as a whole. This paper exam
ines and interprets the results of large-scale clinical trials of glycoprot
ein IIb/IIIa inhibition during PCI and reviews directions for future study
with this unique class of agents. Coronary Artery Dis 10:553-560 (C) 1999 L
