Neuroleptics: preclinical and clinical differences

Neuroleptics: preclinical and clinical differences In this review we propose that the clinical and preclinical effects of neuroleptic drugs justify a distinction between classical and atypical neuroleptic drugs. Binding, biochemical, electrophysiological and behavioural studies have revealed clearcut differences between classical neuroleptics (like haloperidol and fluphenazine) and atypical neuroleptics (such as clozapine, thioridazine and remoxipride). These large differences are likely due to differences in the workingmechanisms. In view of the clinical relevance of these findings it is therefore both justified and essential to subdivide the neuroleptics in two distinct groups: the classical neuroleptics and the atypical neuroleptics.
