Abstract��
OBJECTIVE To establish the pharmacokinetic-pharmacodynamic (PK-PD) characteristics of daurisoline (DS) and dauricine (Dau) in Beagle dogs. METHODS The plasma concentrations of DS and Dau were determined and the prolongation percentage of Q-Tc interval was observed as the effect index. The Sigmoid-Emax model was used to analyze the relationship among the plasma concentrations, time and effects of DS and Dau. RESULTS The relationship between effect and plasma concentration met the Sigmoid Emax model and the model parameter (Ke0 , Emax, EC50,��) were calculated. CONCLUSION The PK-PD model of DS and Dau and the relationship among the effect, plasma concentration and time are established successfully.
