Effects of sulpiride and chlorpromazine on autistic and positive psychotic symptoms in schizophrenic patients--relationship to drug concentrations.
Schizophrenic patients were treated with fixed doses of sulpiride (800 mg/day) or chlorpromazine (CPZ) (400 mg/day) during a period of 8 weeks using a double-blind design. There were 25 patients in each group and all of them fulfilled the Research Diagnostic Criteria (RDC) for schizophrenia. Autistic and psychotic symptoms were rated with subscales developed from the Comprehensive Psychopathological Rating Scale (CPRS). Autistic symptoms were also rated with a subscale of the Nurse's Observation Scale for Inpatient Evaluation (NOSIE). Sulpiride was superior to CPZ in reducing the autistic symptoms. Patients with low concentrations of sulpiride in serum had a better recovery rate from autistic symptoms than those with high concentrations. Both drugs reduced positive psychotic symptoms to the same degree.
