ABSTRACT

Objective: To carry out the pharmacokinetic study in awake animal after multiple dosing of Danshen (Salvia miltiorrhiza) Decoction by blood microdialysis method combined with LC-MS. Methods: The pharmacokinetic study was carried out with awake rabbits as experimental animal, Danshen Decoction as tool drug, and Danshensu as evaluation index combining with microdialysis sampling and LC-MS detection technology after intraday multiple dosing. The pharmacokinetic parameters were obtained by non-compartmental model method. Results: The pharmacokinetic study pattern of multiple dosing was established in awake animal, and the whole process dynamic characteristics were collected. The method was stable, reliable, and simple. Conclusion: This study can make the reference to similar study for other drugs.
