The dose is 300-750 mg once a day in two groups. RESULTS: Both groups endpoint positive and negative symptomes scale(PANSS) and brief psychiatry rating scale(BPRS) score reduced significantly in comparison with the baseline in both (P<0.01). By the PANSS score reduction rate, the clinical effectiveness rate is: quetiapine was 61.61% and chlorpromazine was 64.81%. The incidence of side effect is: quetiapine was 44.54 % and chlorpromazine was 76.27%.
