Özet

In this study, we aimed to determine the drug-drug interaction potential between atorvastatin (ATOR), and talinolol (TAL). Concentration-dependent effects of ATOR on the intestinal permeability of TAL were investigated by an in situ intestinal perfusion method. Dose-dependent effects of ATOR on TAL exposure were evaluated by measuring plasma concentrations after oral administration in rats. ATOR slightly changed the intestinal secretion of TAL in jejunum but not in colon. Plasma AUC levels of TAL were elevated by co-administration of ATOR at low and high doses whereas medium doses of ATOR resulted in a decrease in TAL bioavailability. However, these changes were not statistically significant. In our study, the pharmacokinetics of TAL were not affected by the concurrent use of ATOR in rats. In conclusion, it should be considered that complex interplay between the efflux and uptake transporters in the tissues and inhibition of these transporters by modulating agents may overshadow individual effects of each other.
