[Neuroleptics with prolonged action].

In the last twenty years, the study of long-acting neuroleptic drugs has been active and promising progress in maintenance of psychotic patients. At present, there are several long-acting derivatives of phenothiazines, e.g. thioridazine, or drugs that allow the esterification of phenothiazine, e.g. perphenazine, fluphenazine and pipothiazine. Other esterifiable product is flupenthizol, which is a thioxanthene, and other long-acting drug is chlofluperol, which is a butyrophenone derivative. There is also a new series of neuroleptics, diphenilbultilpiperidine derivatives, such as fluspirilene, pimocide and penfluridol. Our clinical studies with these drugs allows us to state that there is a new revolution in pharmacological psychiatry, with important perspectives in the ways of helping patients.
