title: Antipsychotic medication and smoking prevalence in acutely hospitalized patients with chronic schizophrenia.
abstract: The atypical antipsychotic, clozapine, has been reported to reduce smoking in schizophrenic patients. We sought to determine whether other atypical antipsychotics would also be associated with a decreased prevalence of smoking in this population. Data were obtained from three groups of chronic, hospitalized, schizophrenic patients, receiving either a typical antipsychotic (n=15), clozapine (n=6), or another atypical antipsychotic (n=18). In addition to smoking prevalence, the groups were compared with regard to demographics (age, education), medication (doses, duration of treatment, side-effects), clinical (diagnosis, duration of illness) and behavioral (Wide-Range Achievement Test, Wechsler Adult Intelligence Scale) variables. Smoking prevalence differed significantly among the three groups (P<0.001). Clozapine was associated with a significantly lower incidence of smoking than either typical drugs (P<0.003) or other atypical antipsychotics (P=0. 042). The groups did not differ on demographic or other medication variables or on any of several behavioral measures. However, a diagnosis of paranoid schizophrenia was also significantly correlated with smoking (P<0.01), but not with medication class. Although the cause is still unknown, these results are consistent with reports that clozapine reduces smoking and provide new data on smoking prevalence associated with other atypical agents.
