Abstract
Objectives. The aims of this 13-week study were to examine the efficacy and safety of amisulpride, and effects on cognitive function in patients with schizophrenia after they switched from risperidone. Methods. Twenty-three patients with schizophrenia whose antipsychotic was switched from risperidone to amisulpride were recruited. The efficacy, safety, and cognitive function were assessed. Results. Significant improvements were noted in the PANSS, CGI-S, and MADRS. The prolactin level, but not any of the remaining laboratory variables, increased significantly. The cognitive function improved significantly, particularly in memory subtests. Conclusions. Switching antipsychotic from risperidone to amisulpride in schizophrenia might have significantly improved not only the efficacy, but also various domains of cognitive function. However, hyperprolactinemia existed and was sometimes even worse.
