Abstract

A double-blind eight-week study was carried out to compare the efficacy and safety of risperidone in relation to haloperidol. Sixty-two inpatients suffering from acute schizophrenic or schizoaffective psychoses diagnosed according to ICD-9 were treated with risperidone 2-20 mg daily or haloperidol 2-20 mg daily. The mean total BPRS scores were reduced from 45.5 to 32.4 in the risperidone group and from 43.1 to 28.5 in haloperidol group. There were no significant differences between the two treated groups with regard to the total BPRS score and the percentage of remissions achieved. No statistically significant difference was found between the groups in any of the factors or items except guilt feeling (p < 0.02), anxiety (p < 0.005), and factor I--anxiety/depression--(p < 0.02) in favour of haloperidol. Risperidone had the benefit of a lower incidence of extrapyramidal side-effects.
