Abstract

The effect of cefroxadine, an aminocephalosporin (beta lactam antibiotic) on rat intestinal L-leucine transport has been studied. Cefroxadine inhibited the L-leucine uptake by the intestinal mucosa in a dose-dependent fashion. In vivo studies showed that cefroxadine reduced L-leucine absorption. This effect was irreversible. Only the active transport component of the absorption was inhibited. Oxygen consumption of the mucosa was reduced by cefroxadine which inhibited the activity of the basolateral (Na(+)-K+) ATPase also.
