AB - Objectives The purpose of this study is to investigate the inhibitory or inductive potentials of Yuldahanso-tang (YDT) and Chungsimyonja-tang (CST), herbal formulas for Taeeumin, on cytochrome P450 (CYP450) drug metabolizing enzyme. The mechanisms for the herbal formula-drug interaction has not been well reported in spite of the chance for co-administration with conventional drugs.
Methods To evaluate the interaction potential of YDT-drug or CST-drug, the fluorescence-based enzyme assays on CYP450 isozymes including CYP3A4, CYP2C19, CYP2D6 and CYP2E1 were established in vitro. The inhibitory effects of herbal formulas were characterized with IC50 values.
Results YDT showed inhibitory effects on CYP2D6 and CYP2E1-mediated metabolism, while it exhibited week inhibition on CYP3A4 and CYP2C19 relatively. CST exerted relatively weak inhibitory effects on the four CYP450 isozymes compared to that of YDT.
Conclusions These results suggest that the herbal formula-drug interaction could be occur when YDT are co-administered with drugs mediated by CYP2D6 or CYP2E1.
