Efforts to find a correlation between serum levels of chlorpromazine (CPZ) and clinical effect have been rather unsuccessful, which could be due to fluctuations of CPZ and CPZ metabolite levels during treatment, the complicated metabolism of CPZ, or to varying

Plasma nor1-chlorpromazine (nor1-CPZ) and chlorpromazine concentrations were measured by gas chromatography--mass fragmentometry in 15 inpatients receiving stable doses of chlorpromazine. Nor1-CPZ concentrations averaged 20% of chlorpromazine concentrations and were highly correlated with them. Relative concentrations of nor1-CPZ increased with age.

Data obtained in this preliminary study show that in patients chronically treated either with Chlorimipramine (n = 6) or with Chlorpromazine (n = 2), significant amounts of the corresponding Nor1- and Nor2-metabolites were detected in plasma. The role of these

Thirty-seven newly admitted schizophrenic patients were treated with an open and flexible dosage of chlorpromazine for 3 months after receiving a test dose. Levels of chlorpromazine, demethylated chlorpromazine and chlorpromazine sulfoxide 3 h after the test dose were measured. Twenty-three
