INFLUENCE OF VILDAGLIPTIN AND GLIQUIDONE COMBINATION ON P-GLYCOPROTEIN FUNCTIONAL ACTIVITY AND EXPRESSION ON THE BACKGROUND OF NORM AND IN EXPERIMENTAL ALLOXAN-INDUCED DIABETES MELLITUS TYPE 2

In the in vivo study on rabbits investigated the effect of the vildagliptin and gliqui-done combination on the background of norm and experimental alloxan-induced diabetes mellitus (DM) type 2 on the P-glycoprotein (P-gp, ABCB1 protein) functional activity and its expression in the tissues of the jejunum, liver, kidney and the blood-brain barrier. Introduction of combination of vildagliptin at a dose of 5 mg/kg and gliquidone 10 mg/kg body weight on the background of norm for 14 days did not result in P-glycoprotein changes. On the 5-day of the cancellation of this combination observed inhibition of transporter protein functional activity without altering its expression. In the combination therapy of vildagliptin and gliquidone alloxan-induced diabetes type 2 showed complete recovery of P-glycoprotein functional activity and expression reduced on the pathology background. On the 5-day of treatment withdrawal again occurred inhibition of functional activity of the transporter protein and a decrease in its expression.
