About eptifibatideglycoprotein iib/iiia inhibitor, antiplatelet agent (platelet aggregation inhibitor).indication for treatment of myocardial infarction and acute coronary syndrome.pharmacodynamics eptifibatide is an anti-coagulant that selectively blocks the platelet glycoprotein iib/iiia receptor. eptifibatide is a cyclic heptapeptide derived from a protein found in the venom of the southeastern pygmy rattlesnake (sistrurus miliarus barbouri). it belongs to the class of the so called arginin-glycin-aspartat-mimetics and reversibly binds to platelets.mechanism of action eptifibatide inhibits platelet aggregation by reversibly binding to the platelet receptor glycoprotein (gp) iib/iiia of human platelets, thus preventing the binding of fibrinogen, von willebrand factor, and other adhesive ligands. inhibition of platelet aggregation occurs in a dose- and concentration-dependent manner.
