Evidence-based pharmacotherapy of schizophrenia.

The introduction of the new-generation antipsychotics has changed the way we treat patients with schizophrenia. This article reviews these agents, focusing mainly on the published randomized controlled trials and meta-analyses in which the new-generation antipsychotics are compared with placebo, conventional antipsychotics or with one another. Agents included are risperidone, olanzapine, quetiapine, ziprasidone, sertindole, amisulpride and aripiprazole. Acute-phase and maintenance studies are reviewed, as well as randomized trials for pre-psychotic, first-episode schizophrenia and refractory schizophrenia. Finally, specific areas of current clinical interest are dealt with. These are: conventional vs. new-generation antipsychotics, head-to-head comparisons of new-generation antipsychotics, and side-effect profiles.
