A high-performance liquid chromatography method with diode array detection (HPLC-DAD) was developed for quantification of aripiprazole and dehydro-aripiprazole, in human plasma. After a simple liquid–liquid extraction, chromatographic separation was carried out on a C18 reversed-phase column, using an ammonium buffer–acetonitrile mobile phase (40:60, v/v). The total run time was only 7 min at a flow-rate of 1.0 ml/min. The precision values were less than 12% and the accuracy values were ranging from 98 to 113% and the lower limit of quantification was 2 ng/ml for both compounds. Calibration curves were linear over a range of 2–1000 ng/ml. The mean trough plasma concentrations in patients treated with aripiprazole were 157 and 29 ng/ml for aripiprazole and dehydro-aripiprazole, respectively.
