Brief introduction:
Eptifibatide (Integrilin, Millennium Pharmaceuticals, also co-promoted by Schering-PloughEssex), is an antiplatelet drug of the glycoprotein IIbIIIa inhibitor class.[1] Eptifibatide is a cyclic heptapeptide derived from a protein found in the venom of the southeastern pygmy rattlesnake (Sistrurus miliarius barbouri).
It belongs to the class of the so-called arginin-glycin-aspartat-mimetics and reversibly binds to platelets. Eptifibatide has a short half-life. The drug is the third inhibitor of GPIIbIIIa that has found broad acceptance after the specific antibody abciximab and the non-peptide tirofiban entered the global market.
Indications
Eptifibatide is used to reduce the risk of acute cardiac ischemic events (death andor myocardial infarction) in patients with unstable angina or non-ST-segment-elevation (e.g., non-Q-wave) myocardial infarction (i.e., non-ST-segment elevation acute coronary syndromes) both in patients who are to receive non surgery (conservative) medical treatment and those undergoing percutaneous coronary intervention (PCI).
The drug is usually applied together with aspirin or clopidogrel and (low molecular weight or unfractionated) heparin.
