Pharmacokinetic interactions between empagliflozin and donafenib/lenvatinib in rats
摘要
Abstract
Objective To investigate the influence of empagliflozin combined with donafenib or lenvatinib on the pharmacokinetic parameters of each drug,and to provide a reference for combined medication in clinical practice.Methods A total of 48 healthy male Sprague-Dawley rats were divided into 8 groups:empagliflozin group 1 and 2,donafenib group,lenvatinib group,donafenib pretreatment+empagliflozin group,lenvatinib pretreatment+empagliflozin group,empagliflozin pretreatment+donafenib group,and empagliflozin pretreatment+lenvatinib group,with 6 rats in each group.The doses of empagliflozin,donafenib,and lenvatinib were 2.5 mg/kg,40 mg/kg,and 1.2 mg/kg,respectively.The rats in the empagliflozin group,donafenib group,and lenvatinib group were given a blank solvent by gavage for 7 consecutive days,followed by a single dose of empagliflozin,donafenib,or lenvatinib on day 7 after the administration of the blank solvent;the rats in the pretreatment groups were given the pretreatment drug by gavage for 7 consecutive days,followed by a single dose of drug combination on day 7 after administration of the pretreatment drug.Blood samples were collected at different time points,and plasma was separated to measure the concentration of each drug.A validated ultra-performance liquid chromatography-tandem mass spectrometry method was used to measure the plasma concentrations of donafenib,lenvatinib,and empagliflozin,and a non-compartmental model was used to calculate the main pharmacokinetic parameters of each drug(area under the plasma concentration-time curve[AUC],time to peak[Tmax],peak concentration[Cmax],and half-life time[t1/2]).The independent-samples t test was used for comparison of normally distributed continuous data between two groups,and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups.Results Compared with the empagliflozin group,the donafenib pretreatment+empagliflozin group had significant increases in the AUC0-t and AUC0-∞ of empagliflozin(P=0.011 and 0.008),while the lenvatinib pretreatment+empagliflozin group had no significant change in the AUC of empagliflozin,with a slightly shorter Tmax(P=0.019).Compared with the donafenib group,the empagliflozin pretreatment+donafenib group had significant increases in the AUC0-t and AUC0-∞ of donafenib(P=0.027 and 0.025),as well as a significant increase in Cmax(P=0.015)and significant reductions in CLz/F and Vz/F(P=0.005 and 0.004);compared with the lenvatinib group,the empagliflozin pretreatment+lenvatinib group had a reduction in the t1/2 of lenvatinib by approximately 5 hours(P=0.002),with a trend of reduction in AUC0-t(P>0.05).Conclusion Empagliflozin combined with donafenib may alter the pharmacokinetic parameters of both drugs,leading to a significant increase in the exposure levels of both drugs,and efficacy and adverse reactions should be monitored during co-administration.There are no significant changes in the exposure levels of empagliflozin and lenvatinib during co-administration.关键词
