Objective:To determine parameters of pharmacokinetics in healthy volunteers
provide a scientific basis for clinical application of Yinhuang compound microenema.Method:HPLC was used to determine the concentrations of chlorogenic acid and baicalin in the plasma samples of healthy volunteers
then analyze these data by the pharmacokinetics program 3P97 to determine the parameters of pharmacokinetics and the compartmental model for both ingredients inYinhuang compound microenema.Result:Baicalin showed two compartment model in healthy volunteers and the main parameters of pharmacokinetics were as follows:T1/2α of 0.325 h
T1/2β of 2.370 h
AUC of 6.236×10-3 g·h·L-1-2g·h·L-1
Tm of 0.267h
Vd of 2.423 L.Conclusion:The main components in Yinhuang compound microenema
baicalin and chlorogenic acid
were absorbed quickly and completely after rectal administration.
