Abstract:
Perphenazine belongs to the group of phenothiazine-based neuroleptic drugs frequently used in the long-term treatment of psychotic disorders. In this work, a new capillary zone electrophoresis (CZE) method for the rapid determination of perphenazine (PPZ) in pharmaceutical preparations and human blood serum was developed. Using solid-phase extraction (SPE) as a preclean/purification and preconcentration step before CZE analysis, a detection limit of 3 ng/mL for the monitoring of PPZ in blood serum (for a signal-to-noise ratio of 3) was reached.
