Abstract

Abstract : Oldenlandia diffusa has been used to treat various cancers. Cytochrome P450, a drug metabolic enzyme, might be influenced by herbal medicine. Currently, the problem that remains is the effective treatment in drug-drug interaction situation. Potential influences of Oldenlandia diffusa were elucidated on the CYP450 activities in rats using a cocktail method. Blood samples were precipitated by acetonitrile. Quantitative determination of target test object was done by ultra-performance liquid chromatography tandem mass spectrometry detection. Influences of oldenlandia diffusa on the activities of five CYP450 subtypes in rats were evaluated by five specific probe drugs (phenacetin for CYP1A2, omeprazole for CYP2C19, tolbutamide for CYP2C9, metoprolol for CYP2D6, and midazolam for CYP3A4) according to the pharmacokinetic parameters changes. No statistically significant difference (P > 0.05 ) in pharmacokinetic behaviors can be observed in the five probe drugs. There is a potential guidance on clinical drug combination with Oldenlandia diffusa . Oldenlandia diffusa in compound preparation showed well security.
