With the introduction of atypical neuroleptics, the therapy of schizophrenia has been improved by a group of antipsychotic substances characterized by better tolerability concerning extrapyramidal side effects and higher efficiency against negative symptoms. However, these atypical antipsychotics are not a homogeneous class of drugs but rather represent a group of substances with very different neurobiologic, pharmacologic, and clinical features. This fact and the growing variety of available atypical neuroleptics illustrate the difficulty in choosing the "right" antipsychotic drug for each patient. The aim of this investigation was to evaluate preliminary empirical data for possible differential indication of atypical neuroleptics by a questionnaire-based survey of 192 physicians in ten psychiatric hospitals active in the biological psychiatry work group of the German Federal Directors' Conference.
