Enantioselective determination of dimethindene in urine after oral administration of racemic dimethindene.
A sensitive high-performance liquid chromatographic determination of dimethindene and its metabolite N-demethyldimethindene in urine has been developed. The quantitative analysis was followed by determination of the enantiomeric ratio of dimethindene on an alpha 1-AGP column (EnantioPac). The urinary data for nine volunteers after oral administration of racemic dimethindene are presented. The isolation, identification and synthesis of the metabolite N-demethyldimethindene are reported.
