【摘要】研究香丹注射液在大鼠体内对华法林抗凝作用的影响。将大鼠随机分组并给药,于设定的系列时间点取血。测定凝血指标PT(prothrombin time,凝血酶原时间)和APTT(activated partial thromboplastin time,活化部分凝血活酶时间)并计算INR(international normalized ratio,国际标准化比值)。采用UPLC-MS/MS技术测定华法林对映体血药浓度,用DAS 2.0软件计算药代动力学参数,进行统计学分析比较组间差异。单剂量华法林研究结果表明,香丹注射液本身对PT,APTT及INR均无影响,但与华法林联用后,可使PT和INR升高(P<0.01),对APTT无影响;两药联用后,S-华法林的Cmax,AUC0-t,AUC0-∞升高(P<0.01),t1/2延长(P<0.01),而R-华法林的药动学参数无显著变化。稳态华法林研究结果表明,两药合用后,PT和INR升高(P<0.05),S-华法林血药浓度升高(P<0.01),R-华法林血药浓度无显著变化。研究结果表明,香丹注射液本身对凝血指标无影响,但可通过减慢S-华法林代谢而增强华法林的抗凝作用。

【Abstract】This study aimed at exploring the effect of Xiangdan Injection on anticoagulation of warfarin in rats in vivo. Rats were randomly assigned into different groups and then administered. Subsequently, the blood samples were collected at a set series of time points for the measurement of prothrombin time (PT) and activated partial thromboplastin time (APTT) values, and the international normalized ratio (INR) was calculated. The plasma concentrations of warfarin enantiomers were determined by UPLC-MS/MS technology, and pharmacokinetic parameters were calculated by DAS 2.0 software. Statistical analysis was performed to compare differences between the groups. Single-dose study of warfarin showed that Xiangdan Injection alone had no effects on PT, APTT or INR. When Xiangdan Injection was co-administered with warfarin, PT and INR values increased (P < 0.01), while APTT was unaffected; after co-administration of the two drugs, Cmax, AUC0-t, and AUC0-∞ of S-warfarin increased (P < 0.01), and t1/2 prolonged (P < 0.01), while the pharmacokinetic parameters of R-warfarin changed insignificantly. Steady-state study of warfarin showed that after co-administration of the two drugs, the PT and INR values increased (P < 0.05), and the plasma concentration of S-warfarin increased (P < 0.01), while the plasma concentration of R-warfarin changed insignificantly. The results have suggested that Xiangdan Injection itself has no effect on coagulation index while can enhance the anticoagulation of warfarin by delaying the metabolism of S-warfarin.
