title: Is there a role for oral blockade of platelet glycoprotein IIb/IIIa receptors in coronary and cerebrovascular disease?
abstract: The success of intravenous platelet glycoprotein (GP) IIb/IIIa receptor blockers as potent antithrombotic therapies has ignited interest in the research and development of oral agents with the intention of extending the initial clinical benefits proven with intravenous GP IIb/IIIa blockers to long-term care with the use of oral agents. Nonetheless, results of the recently published Blockade of the Glycoprotein IIb/IIIa Receptor to Avoid Vascular Occlusion (BRAVO) trial support the disappointing results of the earlier published studies, which revealed that the use of oral GP IIb/IIIa inhibitors was associated with an unacceptable increased mortality. Further research to elucidate the mechanism of this increased fatality risk is warranted before any further clinical studies with the oral GP IIb/IIIa inhibitors can be ethically justified.
