埃索美拉唑及泮托拉唑对氯吡格雷抗血小板聚集作用的影响

Influence of pantoprazole and esomeprazole on the anti - platelet aggregation effect of clopidogrel

目的 检测联合应用氯吡格雷与质子泵抑制剂前后的血小板聚集率,通过比较用药前后的的血小板聚集率的差值,探讨埃索美拉唑、泮托拉唑是否会影响氯吡格雷的抗血小板作用.方法 入选200例急性冠状动脉综合征患者,均给予双重抗血小板聚集治疗(阿司匹林肠溶片100 mg/d,氯吡格雷负荷量300 mg后75 mg/d维持),分为埃索美拉唑组(埃索美拉唑20 mg/d)60例,泮托拉唑组(泮托拉唑40 mg/d)60例及不合用质子泵抑制剂的对照组80例.于用药前及用药后7 d应用比浊法测定ADP诱导的血小板最大聚集率及住院期间、1个月内的主要心血管事件,比较三组间血小板聚集率前后差值及主要心血管事件(非致命性心肌梗死,非致命性卒中和死于心血管疾病)发生率差异有无统计学意义.结果 三组间血小板聚集率的差值在对照组(26.7±3.3)%、埃索美拉唑组(26.5±3.6)%、泮托拉唑组(25.6±2.9)%差异无统计学意义(P＞0.05),主要心血管事件发生率差异无统计学意义(P＞0.05).结论 泮托拉唑、埃索美拉唑不影响氯吡格雷的抗血小板聚集作用.

Objective To determine the platelet aggregation rates before and after the usage of clopidogrel in combination with proton pump inhibitors and compare the differences of the rates of platelet aggregation in order to explore whether esomeprazole, pantoprazole will affect the anti-platelet aggregation effect of clopidogrel. Methods Two hundred patients with acute coronary syndrome were treated with dual antiplatelet aggregation therapy ( aspirin enteric - coated tablets 75 mg/d, clopidogrel after 300 mg loading dose 75 mg/d maintenance), and were divided into three groups: esomeprazole group (Esomeprazole 20 mg/d) 60 cases, pantoprazole group (Pantoprazole 40 mg/d) 60 cases and control group ( without proton pump inhibitors) 80 cases. The ADP - induced maximum platelet aggregation rates were detected by Turbidimetry on the day before and 7 days after the medication. The differences of the rate of platelet aggregation in the three groups before and after the medication and the incidence of major cardiovascular events were recorded. Results There was no significant difference in the platelet aggregation rate of the three groups,which were (26.7 ± 3.3) % in the control group, (26.5 ± 3.6) % in the esomeprazole group and (25.6 ± 2.9 ) % in the pantoprazole group. Conclusions Pantoprazole and esomeprazole do not affect the anti-platelet aggregation effect of clopidogrel.
