| Research Abstract |
In the present study, we aimed to clarify the contribution of OATP/Oatp and P-gp to the intestinal absorption of various drugs by means of various in vitro, in situ and in vivo experimental techniques. Trough the studies with various drugs including talinolol and pravastatin, pitavastatin, finally, this study revealed that OATP/Oatp is involved in intestinal drug absorption and the contribution of OATP/Oatp-mediated uptake was apparently attenuated by P-gp-mediated efflux in intestinal drug absorption process.
