RESUMEN

BACKGROUND: Xuesaitong dispersible tablet (XST) product has been clinically proven to be effective for treating cardio-cerebrovascular disease. Furthermore, herb-drug interactions between the XST product and drugs that are commonly co-administered, such as aspirin (ASA), must be explored to ensure safe clinical use. STUDY DESIGN AND METHODS: The current study aims to investigate whether the XST product interacts with ASA when they are administered concomitantly to ensure safety and efficacy. A ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method was developed for the simultaneous determination of ginsenoside Rg1 (Rg1), ginsenoside Rd (Rd), notoginsenoside R1 (R1) and salicylic acid (SA) in rat plasma to investigate the pharmacokinetic interaction of XST and ASA in blood stasis model rats. RESULTS AND CONCLUSION: The ASA and XST combination noticeably altered R1 and Rg1 absorption, distribution and disposition. This study indicates that co-administration of XST and ASA can cause an apparent herb-drug pharmacokinetic interaction in blood stasis model rats.

RESUMEN

A rapid and high sensitive ultra high performance liquid chromatography with tandem mass spectrometry method for the simultaneous determination of notoginsenoside R1 and ginsenoside Re in rat plasma was developed. The analytes and internal standard, digoxin, were extracted from rat plasma via protein precipitation with methanol and separated on an Phenomenex Gemini C18 column within 2 min. Quantitation was performed on a triple quadrupole mass spectrometer employing electrospray ionization technique, operating in multiple reaction monitoring and positive ion mode. The precursor to product ion transitions monitored for notoginsenoside R1, ginsenoside Re, and internal standard were m/z 955.5→775.5, 969.6→789.1, and 803.6→283.1, respectively. The assay was validated with linear range of 1.9-380 ng/mL for notoginsenoside R1 and 0.5-100 ng/mL for ginsenoside Re. The intra- and interday precisions (RSD%) were within 8.96% for each analyte. The absolute recoveries were greater than 93% for R1 and 96% for Re. Each analyte was stable during all sample storage, preparation, and analytic procedures. The method was successfully applied to a pharmacokinetic study of Xuesaitong dispersible tablets in eight rats.
