AbstractThe prognosis in patients with schizophrenia is worsened the longer the duration of psychosis before institution of effective antipsychotic therapy and the greater the number of psychotic relapses. Use of traditional antipsychotic medications has been limited by their substantial side effects and failure to achieve long-term control of symptoms in some cases. New "atypical" antipsychotic drugs show promise for the treatment of resistant cases of schizophrenia and improvement in patient tolerance and compliance. These medications have been more successful than traditional antipsychotic drugs in treating the negative symptoms of schizophrenia, such as social withdrawal and apathy. The atypical antipsychotic drugs produce fewer extrapyramidal side effects and no tardive dyskinesia or dystonia. However, they are associated with induction of neuroleptic malignant syndrome, and clozapine can produce fatal agranulocytosis. Atypical antipsychotic drugs on the market currently include clozapine, risperidone and olanzapine. Use of these medications in selected patients who do not benefit from, or cannot tolerate, traditional agents is an important step in improving the lives of patients with schizophrenia.
