The concomitant use of carbapenem antibiotics with valproic acid has been prohibited because carbapenems induced a decrease in plasma concentration of valproic acid in epileptic patients during valproic acid therapy. Our previous in vivo study in rats proposed that inhibition by carbapenem of the intestinal absorption of valproic acid might be a possible mechanism for the drug-drug interaction. To demonstrate the hypothesis, we examined the effects of imipenem and panipenem on intestinal transepithelial transport of valproic acid using Caco-2 cell monolayers. Imipenem and panipenem inhibited the transport of [14C]-valproic acid across the Caco-2 cell monolayers from apical-to-basolateral side in a concentration-dependent manner, although they had no effect on the uptake of [14C]-valproic acid by Caco-2 cells. The inhibition by the carbapenems of the valproic acid transport was found even when they were added to only the basolateral side. From these results, the carbapenems may inhibit the absorption of valproic acid at the basolateral membrane of intestinal epithelial cells, which contributes to the decrease in plasma concentration of valproic acid after oral administration.
