目的:观察盐酸沙格雷酯对大鼠细胞色素 P4502D1/2(CYP2D1/2)的底物右美沙芬药动学的影响。方法♂ SD大鼠,随机分成2组,对照组按右美沙芬组10 mg·kg -1灌胃给药,盐酸沙格雷酯组按右美沙芬和盐酸沙格雷酯均10 mg ·kg -1同时灌胃给药,按不同时间从大鼠眼底静脉丛取血,血样处理后,用 LC-MS /MS 法测定大鼠血浆中右美沙芬的浓度,用 DAS 2.0软件进行分析,求出其主要药代动力学参数。结果盐酸沙格雷酯组与对照组比较,右美沙芬的 T12明显延长(2.49 h ±0.93 h vs 1.47 h ±0.20 h,P <0.05),Cmax明显升高(325.7μg·L -1±133.2μg·L -1 vs 104.5μg·L -1±52.4μg·L -1,P <0.05),AUC0-t (785.5μg·L -1·h ±451.9μg·L -1·h vs 244.8μg·L -1·h ±168.3μg·L -1·h,P <0.05)和 AUC0-∞(804.7μg·L -1·h ±445.6μg ·L -1·h vs 251.4μg·L -1·h ±173.4μg·L -1·h,P <0.05)明显增大。结论盐酸沙格雷酯在大鼠体内对右美沙芬的代谢有抑制作用,能降低其消除过程。

Aim To investigate the influence of sarpog-relate hydrochloride (SH)on the pharmacokinetic pro-file of dextromethorphan (DM),the typical substrate of CYP2D1 /2,in rats when they were administered co-instantaneously.Methods A total of 1 2 SD rats were randomly divided into two groups:the control group (DM,1 0 mg·kg-1 )and the sarpogrelate group (SH, 1 0 mg·kg-1 ;DM,1 0 mg·kg-1 ),which received in-tragastric administration.Plasma samples were collected immediately before and at different time points after drug administration.A LC-MS /MS method was used to determine the concentrations of DM in rat plasma. Pharmacokinetic parameters were analyzed using Drug and Statistics (DAS 2.0).Results There were signif-icant differences in the pharmacokinetic parameters of DM,including T1 2 (2.49 h ±0.93 h vs 1 .47 h ±0.20 h,P <0.05 ),Cmax (325.7 μg·L -1 ±1 33.2 μg· L -1 vs 1 04.5μg·L -1 ±52.4 μg·L -1 ,P <0.05), AUC0 -t(785.5 μg·L -1 ·h ±451 .9 μg·L -1 ·h vs 244.8 μg·L -1 ·h ±1 68.3μg·L -1 ·h,P <0.05) and AUC0 -∞(804.7 μg·L -1 ·h ±445.6 μg·L -1 ·h vs 251 .4 μg·L -1 ·h ±1 73.4 μg·L -1 ·h,P<0.05 )between the two groups.Conclusion SH could significantly inhibit the elimination of DM,the substrate of CYP2D1 /2 in rats.
