Platelet adhesion and aggregation at the site of coronary stenting can have catastrophic clinical and economic consequences. Therefore, effective platelet inhibition is vital during and after percutaneous coronary intervention. Eptifibatide is an intravenous antiplatelet agent that blocks the final common pathway of platelet aggregation and thrombus formation by binding to glycoprotein IIb/IIIa...

BACKGROUND In the PURSUIT trial, eptifibatide significantly reduced the 30-day incidence of death and myocardial infarction relative to placebo in 9461 patients with an acute coronary syndrome (unstable angina or non-Q-wave myocardial infarction). METHODS AND RESULTS We conducted a 2-part prospective economic substudy of the 3522 US patients enrolled in PURSUIT: (1) an empirical intention-to-...

AIMS Thrombolytic therapy restores coronary patency in patients with acute myocardial infarction, although normal perfusion (TIMI 3 flow) is not achieved in all patients. In an attempt to improve TIMI 3 flow, a combination of full-dose streptokinase, aspirin and escalating dosages of a platelet glycoprotein IIb/IIIa receptor blocker, eptifibatide, vs placebo were tested. METHODS AND RESULTS A...

Aim. To study the safety and efficacy of Angipure in acute ST-segment elevation coronary syndrome (STE-ACS) high-risk percutaneous transluminal angioplasty (PTCA) compared with eptifibatide. Material methods . The included 157 patients STE-ACS. High-risk PTCA massive or total artery thrombosis, noreflow/slow-reflow phenomenon, stent thrombosis. Fifty-five people received at a dose 0,72 mg/kg, 5...

BACKGROUND Pharmacodynamics of eptifibatide, a cyclic heptapeptide antagonist of platelet glycoprotein IIb/IIIa, are substantially altered by anticoagulants that chelate calcium, resulting in overestimation ex vivo of the in vivo effects of this agent. We conducted a dose-ranging study to characterize the pharmacodynamics and pharmacokinetics of eptifibatide under physiological conditions. ME...

AIM The aim of the present study was to investigate the effect of GPIIb/IIIa inhibition with eptifibatide and tirofiban on the expression of cellular adhesion molecules on monocytes at different temperatures. MATERIALS AND METHODS Circulation of blood from six volunteers was performed in an extracorporal circulation model at 36°C and 18°C for 30 min. The blood of each donor was prepared eithe...

Background—Platelet glycoprotein (GP) IIb/IIIa antagonists prevent the composite end point of death or myocardial infarction (MI) in patients with acute coronary syndromes. There is uncertainty about whether this effect is confined to patients who have percutaneous coronary interventions (PCIs) and whether PCIs further prevent death or MI in patients already treated with GP IIb/IIIa antagonists...

BACKGROUND GPIIb/IIIa inhibitors abciximab and eptifibatide have been shown to inhibit platelet aggregation in ischemic heart disease. Our aim was to test the efficacy of abiciximab (Reo Pro) or eptifibatide (Integrilin) alone or in combination with plasminogen activator (t-PA) in an experimental model of ischemia reperfusion (I/R) in hamster cheek pouch microcirculation visualized by fluoresce...

A 31-year-old woman at 32 weeks' gestation presented with an ST segment elevation myocardial infarction with subsequent bare metal stent placement. A multidisciplinary team coordinated the delivery plan, including anticoagulation and delivery mode. Because the patient was at high risk for stent thrombosis, clopidogrel was discontinued after 4 weeks and bridged with eptifibatide for 7 days. Epti...

A new, rapid, economical and isocratic reverse phase high performance liquid chromatography (RP-HPLC) method was developed for the determination of eptifibatide acetate, a small synthetic antiplatelet peptide, in bulk drug substance and pharmaceutical dosage forms. The developed method was validated as per of ICH guidelines. The chromatographic separation was achieved isocratically on C18 colum...
