Autoradiographic study of 14C-sulpiride in monkey

Abstract

Substituted benzamides have been the object of numerous metabolic studies including many by whole body autoradiography of rats and mice. The present study reports autoradiographic data concerning 14C-labelled Sulpiride in monkey. The Study was limited to the brain in order to elucidate the controversial question as to whether the drug can cross the blood-brain barrier. The results showed that in monkey, as in rat and mouse, there is no localization in the brain as can be clearly seen on the autoradiograms. In view of these results and of the undeniable neuroleptic properties of Sulpiride, an indirect mode of action through the release of endogenous mediators is proposed.
