title: Atypical and typical neuroleptics in acute schizophrenia and related delusional disorders. Drug choice, switching and outcome under naturalistic treatment conditions.
abstract: Atypical neuroleptics have improved drug treatment in schizophrenia. However, their use varies greatly between countries and continents. Recent metaanalyses have deemphasized the range and magnitude of their superiority compared to typical neuroleptics. Aims of the present study were to contribute effectiveness data to this discussion. In 725 inpatients with ICD-10 diagnoses F20, 22-25 from four German psychiatric inpatient units acute neuroleptic treatment and outcome were analyzed under naturalistic conditions. Treatment strategies were stratified post hoc to answer the question, which proportion - and which kind - of patients are primarily given atypicals or typicals, for how long, at which rate and when the atypical/typical drugs are switched to typical/atypical drugs, and what the respective outcomes are. As the results demonstrate, atypicals were administered one time during inpatient treatment in nearly 48% of the patients, however as first choice drugs in only 15% of this population. Treatment change occurred in 28% after 5-6 weeks irrespective of the first drug choice. Outcome differences were, if at all, only modest and not systematically biased towards a single strategy. In conclusion, frequency of inpatient treatment with atypical neuroleptics corresponds to pharmaco-epidemiological data in Europe, but is still lower than in the US. Contrary to contemporary guideline recommendations atypical neuroleptics under routine inpatient treatment conditions were scarcely administered as first choice treatment, and acute clinical outcome is comparable to that under treatment with typical neuroleptics. Reasons and implications of these findings considering the methodological limitations are discussed.
