[Problems in evaluating new antipsychotic drugs].
A number of novel antipsychotics were registered and introduced into clinical practice in the last decade. These include olanzapine, quetiapine, risperidone, sertindole and zotepine as well as ziprasidone, which is still in the registration process. It quickly became apparent, that it is not always easy to translate results from phase II and III clinical trials into everyday clinical practice. In this context, we discuss methodological aspects that mainly deal with selection of patients for clinical trials and clinical trial methodology. Next to that, an overview of the current knowledge concerning novel antipsychotics is given. There is no doubt that these drugs broaden the therapeutic spectrum made available to patients suffering from schizophrenia. On the other hand, it is evident that there is still a need for a critical evaluation of the risk-benefit-ratio of novel antipsychotics. Clinical psychiatrists also face the challenge to modify some of the traditional treatment approaches. These prerequisites will allow the embedding of novel antipsychotics into modern integrative treatment concepts of schizophrenia.
