Cyclosporin A, a substrate of
P-glycoprotein
(
P-gp
), is known to cause cholestasis in humans and in rat experimental models.
Tauroursodeoxycholate
is reported to be effective in CyA-induced cholestasis in rats. In the present study, to investigate the mechanism of the inhibition of CyA induced cholestasis, effect of bile acids on biliary cyclosporin A excretion was studied in rats. Infusion of both taurocholate and tauroursodeoxycholate at the rate of 0.8 mmol/min per 100 g bodyweight increased bile flow and biliary cyclosporin A excretion, and the extent was more prominent with tauroursodeoxycholate. It was suggested that these findings were caused by the enhanced vesicular targeting of
P-gp
to the canalicular membrane by bile acids, thus increasing the numbers of
P-gp
in the canalicular membrane.
