title: Determination of the enantiomers of chlorpheniramine and its main monodesmethyl metabolite in urine using achiral-chiral liquid chromatography.
abstract: The enantiomers of chlorpheniramine and its monodesmethyl metabolite were determined separately in urine by using a coupled achiral-chiral chromatographic system. The two enantiomers of the studied compound and the internal standard were separated from the biological matrix on a cyanopropyl column and reinjected into a chiral amylose AD column where the two enantiomers were separated and quantified by UV detection. The method was validated for chlorpheniramine and for the metabolite within the range 0-1000 ng/ml. It was also applied in a pilot pharmacokinetic study to samples from a volunteer given 8 mg of racemic chlorpheniramine by mouth.
