Typical neuroleptics vs. atypical antipsychotics in the treatment of acute mania in a natural setting.

The present retrospective chart review documents the treatment practice of in-patients suffering from acute manic or hypomanic episodes, at the Department of General Psychiatry, Medical University of Vienna between 1997 and 2001. The aim of the study was to compare the efficacy of typical neuroleptics and atypical antipsychotics as add-on therapy to mood stabilizers. A total of 119 episodes of consecutively admitted patients with ICD-10-defined acute mania ( n =106) or hypomania ( n =13) were included in a retrospective analysis. Two subgroups were separated out of the whole patient sample according to the medication used: (a) mood stabilizer+typical neuroleptic ( n =27) and (b) mood stabilizer+atypical antipsychotic ( n =39). The treatment patterns of both subgroups during the first 14 d of in-patient treatment were evaluated. The therapeutic effect was measured by the Clinical Global Impression Scale (CGI). Both patient groups showed no differences on CGI at admission. Patients treated with atypical antipsychotics showed a significantly greater clinical improvement after 14 d ( p < 0.005) and on discharge ( p < 0.05) than patients treated with typical neuroleptics. Furthermore, patients treated with atypical antipsychotics developed significantly less extrapyramidal side-effects ( p < 0.01) and were significantly treated less often with benzodiazepines ( p < 0.05) during the first 14 d compared to the group receiving typical neuroleptics. Based on our evaluation and the data available in the literature atypical antipsychotics can be considered as first choice for the treatment of acute mania as add-on therapy to mood stabilizers because of their better efficacy and side-effect profile compared to typical neuroleptics.
