Fluorimetric determination of the quaternary compound trospium and its metabolite in biological material after derivatization with benoxaprofen chloride.
The quantitative determination of the quaternary compound trospium and the corresponding spiroalcohol is described for human biological material. Analysis is performed by alkaline hydrolysis, ion-pair extraction into chloroform, subsequent derivatization with the flurophor benoxaprofen chloride and high-performance liquid chromatographic separation on a reversed-phase column. The limit of quantitation is ca. 1 pmol (1.03 pmol=lng of trospium chloride) per millilitre of plasma.
