Pharmacokinetics Study of Herb-Drug Interaction of Berberine and Glipizide in Beagle Dogs Using UPLC-MS/MS.
Based on the establishment and validation of a UPLC-MS/MS method for detecting glipizide in beagle plasma, the herb-drug interaction (HDI) between berberine and glipizide was studied. After gradient elution separation of glipizide and internal standard, multiple reaction monitoring was used for detection in positive ion mode. The ion reactions used for quantitative analysis were glipizide m/z 446.0 ⟶ 321.0 and IS m/z 307.1 ⟶ 220.0. Six beagle dogs were treated with glipizide alone and berberine intervention, and the pharmacokinetic changes of glipizide were compared. The UPLC-MS/MS method has good linearity and the advantages of being green, simple, sensitive, and fast. After continuous administration of berberine to beagle dogs for 7 days, the pharmacokinetic process of glipizide changed with Cmax, AUC(0-t) and AUC(0-∞) increasing, t1/2 prolonging, and CL and Vd decreasing. When using combination therapy, attention should be paid to possible HDI.
期刊介绍：
International Journal of Analytical Chemistry publishes original research articles that report new experimental results and methods, especially in relation to important analytes, difficult matrices, and topical samples. Investigations may be fundamental, or else related to specific applications; examples being biological, environmental and food testing, and analysis in chemical synthesis and materials processing.
As well as original research, the International Journal of Analytical Chemistry also publishes focused review articles that examine the state of the art, identify emerging trends, and suggest future directions for developing fields.
