Augmentation with amisulpride for schizophrenic patients nonresponsive to antipsychotic monotherapy.
Despite the effectiveness of antipsychotic medications in treatment of schizophrenia, about 30% of patients who receive an adequate treatment have significant persisting symptoms. The problem of treatment-resistant psychosis is an important and difficult one. The aim of this study was to retrospectively evaluate the efficacy and safety of amisulpride augmentation in treatment-resistant schizophrenic patients. To the best of our knowledge, this is the first report about resistant schizophrenic and schizoaffective patients treated with the combinations of risperidone and amisulpride and ziprasidone and amisulpride. Data were collected from patient records. A total of 15 resistant schizophrenic patients (7 men, 8 women, 54.0 +/- 16.9 years old) were included in the study. Before addition of amisulpride, the patients were treated with monotherapy by atypical neuroleptics (clozapine, olanzapine, risperidone, or ziprasidone). The mean amisulpride dose was 693.3 +/- 279.6 mg/d. The mental state of 12 (80%) patients treated with combination was improved. Three (20%) patients showed no change in their mental state. Only 2 patients treated with a combination of risperidone and amisulpride had mild side effects. The results are preliminary and require confirmation in a randomized controlled trial. The authors suggest that amisulpride may be a promising option as an augmentation strategy in treatment-resistant schizophrenic patients.
