Michaela Jahodová Supervisor: PharmDr. Lukáš Červený, Ph.D. Title of diploma thesis: In vitro and ex vivo study of drug-drug interactions of antiretrovirals on intestinal ATP-binding drug transporters The absorption of orally administered drugs takes place especially in the intestine, where it can affect by the activity of drug's ABC transporters located on the apical membrane of the intestinal epithelium. Study of drug interactions in intestinal ABC transporters is essential to ensure effective and safe pharmacotherapy. Testing of bi- directional transport on Caco-2 cells is generally the preferred method for in vitro evaluation of substrates and inhibitors of ABC transporters. Drawbacks of the Caco-2 model increase the need and necessity to introduce new models. A great potential is the involvement of ex vivo methodologies in the human or rat intestine. The aim of the work was to introduce an in vitro methodology using the Caco-2 cell monolayer and the ex vivo methodology of precision-cut rat intestinal slices. By the bi-directional transport method, we analyzed drug interactions of the model substrate P-gp and BCRP Rhodamine 123 (RHD123) and clinically-used tenofovir...
