Effect of storage on the plasma concentration of chlorpromazine and six of its metabolites. 1991

M Chetty, and R Miller
Pharmacology Department, University of Durban-Westville, Republic of South Africa.

The concentrations of chlorpromazine (CPZ) and six of its metabolites in patient plasma samples that had been stored for 24 h at -20 degrees C, for 1 week at -20 degrees C, and for 4 weeks at -70 degrees C were compared. The concentrations of CPZ and six of its metabolites in human plasma spiked with known concentrations and stored at -70 degrees C for either 3 or 12 months were also compared. No significant difference was seen in the concentrations after storage under nitrogen and analysis by a high-performance liquid chromatography technique.

D002746 Chlorpromazine The prototypical phenothiazine antipsychotic drug. Like the other drugs in this class chlorpromazine's antipsychotic actions are thought to be due to long-term adaptation by the brain to blocking DOPAMINE RECEPTORS. Chlorpromazine has several other actions and therapeutic uses, including as an antiemetic and in the treatment of intractable hiccup.
