The effects of halopemide on the release of3H-serotonin,3H-noradrenaline,3H-acetylcholine and3H-GABA from rat frontal cortical slices in vitro were studied and compared to those of its neuroleptic congener R29800, spiperone and haloperidol. Spontaneous3H-serotonin and to a lesser extent3H-noradrenaline outflow were augmented by the agents, while the effects on basal3H-acetylcholine and3H-GABA release were small or absent. Mechanisms explaining these effects are discussed. Depolarization-induced release of serotonin was affected more markedly than the extra overflow of other radiolabeled transmitters, but the statistical significance of the response was limited.
