Abstract:
[Objective] To explore the feasibility and advantages of blood microdialysis technique for the pharmacokinetic study of sinomenine. [Methods] In this study, rats served as the experimental subjects and sinomenine was administered to the rats by intravenous injection. With microdialysis technique for blood sampling, the blood concentration of sinomenine was determined by high performance liquid chromatography (HPLC) and the associated pharmacokinetic parameters were analyzed by 3p97 program. [Results] The pharmacokinetics process of sinomenine in rats presented as the two-compartment model. The half-life of distribution phase was 10.98min and that of elimination phase was 44.71 min. [Conclusion] It is feasible to study pharmacokinetic parameters of sinomenine by using blood microdialysis technique. In comparison with the traditional technique, blood microdialysis technique is superior to the examination of drug blood concentration .
