生脉注射液与参麦注射液在健康人体的药代动力学

目的 比较研究健康志愿者单次静脉滴注生脉注射液(益气养阴中药)和参麦注射液(治疗心脏病的急救中药)的药代动力学.方法 16名健康受试者分成2组,交叉试验,分别单次静滴相同剂量生脉注射液和参麦注射液;用液相色谱-质谱仪检测法测定给药后不同时间点的血药浓度,用DAS 2.0软件计算药代动力学参数.结果 两者的血药浓度-时间曲线均符合二房室模型,健康受试者单次静滴生脉注射液和参麦注射液后主要的药代动力学参数如下.Rg1:Cmax分别为(0.89±0.52),(0.81±0.53)mg·L-1;t1/2分别为(2.01±0.82),(1.78±0.98)h;AUC0-144分别为(1.15±0.44),(1.24±0.84)mg·h·L-1.Re:Cmax分别为(0.26±0.15),(0.27±0.19)mg·L-1;t1/2分别为(0.59±0.34),(0.60±0.44)h;AUC0-144分别为(0.26±0.13),(0.33±0.25)mg·h·L-1.Rb1:Cmax分别为(10.57±8.92),(16.54±11.70)mg·L-1;t1/2分别为(47.98±7.26),(47.17±8.75)h;AUC0-144分别为(346.67±267.89),(525.45±387.32)mg·h·L-1.结论 单次静滴相同剂量的生脉注射液和参麦注射液其药代动力学参数无显著性差异.

Pharmacokinetics of Shengmai and Shenmai injection in healthy volunteers

Objective To compare the pharmacokinetics of Shengmai and Shenmai injection with a single injection administration using a constant speeed in healthy volunteers.Methods Sixteen healthy volunteers were divided into 2 groups and each of whom was administered with 60 mL Shengmai injection in 2 cross periods.The plasma concentrations of Ginsenoside were determined by LC/MS.The pharmarcokinetic parameters Ginsenoside were calculated by DAS 2.0 software.Results The plasma concentration-time curve fits two compart...
