Acute coronary syndromes and non-Q-wave myocardial infarction are often initiated by platelet activation. Eptifibatide is a cyclic heptapeptide and is the third inhibitor of glycoprotein (Gp) IIb/IIIa that has found broad acceptance after the specific antibody abciximab and the nonpeptide tirofiban entered the global market. Gp IIb/IIIa inhibitors act by inhibiting the final common pathway of platelet aggregation, and play an important role in the management of acute coronary syndromes.
This review assesses the evidence for therapeutic value of eptifibatide as a Gp IIb/IIIa inhibitor in patients with acute coronary syndromes.
Several large, randomized controlled trials show that eptifibatide as adjunctive therapy to standard care in patients with non-ST segment elevation acute coronary syndrome is associated with a significant reduction in the incidence of death or myocardial infarction. Data are limited regarding the use of eptifibatide in patients with ST segment elevation myocardial infarction. Cost-effectiveness analysis indicates that eptifibatide is associated with a favorable cost-effectiveness ratio relative to standard care. According to US cost-effectiveness analysis about 70% of the acquisition costs of eptifibatide are offset by the reduced medical resource consumption during the first year. Eptifibatide was well tolerated in most of the trials. Bleeding is the most commonly reported adverse event, with most major bleeding episodes occurring at the vascular access site. Major intracranial bleeds, stroke, or profound thrombocytopenia rarely occurred during eptifibatide treatment.
Eptifibatide has gained widespread acceptance as an adjunct to standard anticoagulation therapy in patients with acute coronary syndromes, and may be particularly useful in the management of patients with elevated troponin or undergoing percutaneous coronary interventions.
急性冠状动脉综合征和非Q波心肌梗死通常由血小板激活引发。依替巴肽是一种环七肽,是继特异性抗体阿昔单抗和非肽替罗非班进入全球市场后,已被广泛接受的第三种糖蛋白(Gp)IIb/IIIa抑制剂。Gp IIb/IIIa抑制剂通过抑制血小板聚集的最终共同途径发挥作用,在急性冠状动脉综合征的治疗中起着重要作用。
本综述评估依替巴肽作为Gp IIb/IIIa抑制剂在急性冠状动脉综合征患者中的治疗价值证据。
多项大型随机对照试验表明,依替巴肽作为非ST段抬高急性冠状动脉综合征患者标准治疗的辅助治疗,可显著降低死亡或心肌梗死的发生率。关于依替巴肽在ST段抬高心肌梗死患者中的应用数据有限。成本效益分析表明,与标准治疗相比,依替巴肽具有良好的成本效益比。根据美国的成本效益分析,依替巴肽第一年约70%的购置成本因医疗资源消耗减少而得到抵消。在大多数试验中,依替巴肽耐受性良好。出血是最常报告的不良事件,大多数严重出血事件发生在血管穿刺部位。依替巴肽治疗期间很少发生重大颅内出血、中风或严重血小板减少症。
依替巴肽作为急性冠状动脉综合征患者标准抗凝治疗的辅助药物已被广泛接受,在肌钙蛋白升高或接受经皮冠状动脉介入治疗的患者管理中可能特别有用。
