ABSTRACT
Fufang Danshen Dripping Pill (FDDP) and Clopidogrel Bisulfate Tablet (CBT) are usually combined for treatment of coronary artery diseases in clinical. To investigate the pharmacokinetic interaction between FDDP and CBT after oral administration of FDDP, CBT and their combination in rats, a novel LC-MS method with segmented scan modes (multiple reaction monitoring and selected ion monitoring) and polarity (positive and negative ionization) was developed. Clopidogrel and the main active ingredients of FDDP, with different chemical and ionization properties, were simultaneously quantified in plasma in a single run. The method was validated in terms of specificity, linearity, precision, accuracy, recovery, matrix effect and stability. As a result, co-administration of FDDP and CBT significantly altered the pharmacokinetic parameters of danshensu, ginsenoside Rb1, dihydrotanshinone I, tanshinone I and tanshinone IIA of FDDP, as well as clopidogrel. Mechanism studies suggested that induction of liver cytochrome P450 isozymes CYP2C11 and CYP3A1 by co-administration, as well as inhibition of carboxyl esterase 1, was partly responsible for FDDP-CBT pharmacokinetic interactions. The developed LC-MS method could be used to simultaneously quantify different types of in vivo analytes in a single run, and the results could be used for clinical medication guidance of FDDP and CBT.
