Pharmacokinetic interaction study between sorafenib and dapagliflozin in rats / 中国临床药理学与治疗学

ABSTRACT

AIM: To explore the pharmacokinetic interactions between sorafenib and dapagliflozin in rats and to provide some theoretical basis for the rational clinical use of the two drugs. METHODS: An ultra -performance liquid chromatography-tandem mass spectrometry (UPLC / MS / MS) method was developed for the simultaneous determination of sorafenib and dapagliflozin. Male SD rats were randomly divided into 5 groups (6 rats in each group), including 100 mg / kg sorafenib group, 0.5 mg / kg dapagliflozin group, 1 mg / kg dapagliflozin group, and 100 mg/kg sorafenib combined with 0.5 mg/kg dapagliflozin group and 100 mg/kg sorafenib combined with 1 mg / kg dapagliflozin group, for sorafenib and dapagliflozin drug interaction study. All samples were analyzed using a validated UPLC/ MS/MS method, and the main pharmacokinetic parameters were calculated by compartment model. RESULTS: 1 mg/kg dapagliflozin increased the C
