title: Effects of sulpiride and chlorpromazine on depressive symptoms in schizophrenic patients--relationship to drug concentrations.
abstract: Schizophrenic patients were treated with fixed doses of sulpiride (800 mg/day) or chlorpromazine (CPZ) (400 mg/day) over a period of 8 weeks using a double-blind design. There were 25 patients in each group and all the patients were in an acute phase of their disease. They all fulfilled the Research Diagnostic Criteria (RDC) for schizophrenia. Depressive symptoms as rated according to the Comprehensive Psychopathological Rating Scale (CPRS) were present in the patients before treatment was started. The depressive and psychotic symptoms in both groups decreased in parallel during the whole period of treatment. Patients in the sulpiride group recovered more quickly from depressive symptoms than patients in the CPZ group. It was also found that patients with low concentrations of sulpiride or CPZ in serum recovered more completely from depressive symptoms and had fewer extrapyramidal side effects than patients with high drug concentrations.
