RESUMEN
The main objective of the pharmacotherapy of schizophrenia has been, and still is, to obtain optimal therapeutic efficacy, which is seconded by the aim to restrict as far as possible the sometimes severe collateral effects which are acknowledged as being the major drawback to the regular use of neuroleptic agents. Tight from the start, some "atypical neuroleptics" were identified as being of interest for this reason; these included Clothiapine and Clozapine, a more recently discovered drug which is not yet commercially available in Italy. Both of these neuroleptics have been found to offer extremely interesting advantages. The authors now report data referring to the clinical use of these drugs during 1989-1990 in addition to those published in the literature on this subject.
