小儿热感宁注射液在兔体内的药代动力学研究

Pharmacokinetics of Xiaoer Reganning Injection in Rabbits

目的 :研究小儿热感宁注射液在家兔体内的药代动力学特征。方法 :采用高效液相色谱法测定小儿热感宁注射液中主要成分葛根素在兔血浆中的浓度 ,用3p87程序计算药代动力学参数。结果 :小儿热感宁注射液在兔体内的药代动力学过程符合开放二室模型 ,主要药代动力学参数为T1/2α=5 25min ,T1/2β=36 04min ,K10=0 042min ,K12=0 063min ,K21=0 093min ,AUC=2561 49μg/(ml·min) ,CL=4 6ml/(min·kg)。结论

OBJECTIVE:The pharmacokinetics of Xiaoer Reganning injection was determined in rabbits METHODS:The concentrations of puerarin in Xiaoer Reganning injection in plasma were determined by HPLC The analytical column was No _va-pak C18 (4μm,150mm×3 9mm ID) The mobile phase consisted of methol-water(20∶80) The detecting wavelength was 250nm The 3p87 program was used to calculate the pharmacokinetic parameters RESULTS:The in vivo pharmacokinetic course of puerarin in Xiaoer Reganning injection could be described as an open two-compartment model Its main pharmacokinetic parameters were as follows:T1/2(α)=5 25min,T1/2(β)=36 04min,K10=0 042min,K12=0 063min,K21=0 093min,AUC=2 561 49μg/(ml·min),CL=4 6ml/(min·kg) CONCLUSION:This study will provide a scientific basis for clinical use of Xiaoer Reganning injection
