This investigation was carried out to evaluate F-19 nuclear magnetic resonance as an analytical tool for the measurement of the cis(Z) and trans(E) stereoisomers of the antipsychotic drug flupentixol in human serum. The method is based on the integration of appropriate signals of both analytes and an internal standard. The proposed method was applied to the analysis of real samples without any interference, manipulation of large samples, and lengthy instrument time. Experimental parameters were selected to optimize accuracy, precision, and analysis time. The calibration curves in human serum matrix were linear for cis(Z)- and trans(E)-flupentixol over the ranges 4.0-50.0 and 2.6-25.0 mug/mL, respectively, with respective minimum detectable limits (S/N = 3) of 1.67 and 1.72 mug/mL. The method was validated through spike and recovery for the two isomers of flupentixol from a human serum matrix. (C) 2003 Elsevier Inc. All rights reserved.
