A 55 year-old man with unstable angina is treated with an intravenously administered glycoprotein IIb - IIIa inhibitor. The mechanism of action of this agent is the ability to.
Dilate coronary arteries
Inhibit platelet aggregation
Inhibit platelet adhesion
Inhibit atherogenesis
Solution:
Glycoprotein IIb - IIIa

Prevent the action of the platelet surface receptor glycoprotein complex, which is mrequired for formation of fibrinogen bridges between adjacent platelets.
Thus inhibiting platelet aggregation.
