Effect of orange oil on the oral absorption of enrofloxacin in rats.


PMID 22293675

Abstract

This study was conducted to evaluate the oral absorption of enrofloxacin (ENFX) in rats when administered with orange oil or its main component, limonene. Compared with the group administered ENFX alone, the ENFX + limonene group did not show any significant difference in the absorption of ENFX, whereas the extent and rate of absorption of ENFX were significantly decreased in the ENFX + orange oil group (C(max), -43%; T(max), 129%). In addition, t(1/2λz) and MRT of ENFX were prolonged by the concomitant administration of orange oil. The AUCs of ENFX were not affected in the ENFX + orange oil group. These results suggest that decreased oral absorption could reduce the efficacy of ENFX therapy in animals.
