Use of platelet glycoprotein IIb/IIIa receptor inhibitors in acute coronary syndrome and coronary intervention

New strategies in the treatment of acute coronary syndromes have focused on the potential for blocking platelet aggregation through the use of platelet surface membrane glycoprotein (GP) IIb/IIIa receptor inhibitors. The benefits of GPIIb/IIIa inhibition in preventing ischemic complications of interventional treatment have been well defined in patients with unstable angina. In the future, major therapeutic applications for this class of agents may include the stabilization of patients with unstable angina and potentially as single medical therapy, as several recently completed trials have suggested. This article attempts to review recently published clinical trials regarding the use of GPIIb/IIIa receptor inhibitors, and clarify current problems in the use of this agent and directions for future investigation.
