Efficacy and safety of aripiprazole in Chinese Han schizophrenia subjects: A randomized, double-blind, active parallel-controlled, multicenter clinical trial

The study demonstrated that aripiprazole, as well as risperidone, had rapid and persistent efficacy for psychotic symptoms from the first week of therapy. There may be poor efficacy for aripiprazole compared with risperidone for overall improvement, but there were no significant differences in this study. Aripiprazole showed good tolerability with less weight gain and hyperprolactinemia compared with risperidone. The overall efficacy and safety of aripiprazole in Chinese Han schizophrenia subjects were similar to that reported in Western populations.
