Thioridazine: a selective inhibitor of peroxisomal beta-oxidation in vivo

In vivo administration of the phenothiazine drug, thioridazine, inhibits hepatic peroxisomal beta-oxidation in mice. In starving animals, 3-hydroxybutyrate concentration is not decreased by thioridazine treatment. These results provide the first demonstration of thioridazine as a selective inhibitor of peroxisomal beta-oxidation in intact animals. Thioridazine might supply a tool for simulation of pathological conditions in which peroxisomal beta-oxidation is impaired.
