Medikamentenbestimmung mit Elektrospray Tandem-Massenspektrometrie. Drug Monitoring by Electrospray Tandem Mass Spectrometry

Abstract: Zusammenfassung: Die Hochleistungs-Flüssigchro-matographie (HPLC) ist ein universelles Werkzeug für die Bestimmung von Drogen und Medikamentenspiegeln im Blut. Die Detektion des AnaJyten erfolgt vorwiegend durch Lichtabsorptions-oder Fluoreszenzmessung. Einige Medikamente weisen jedoch keinen Chromophor auf, oder die molaren Absorptionskoeffizienten sind sehr klein. Sie entziehen sich so einer empfindlichen Bestimmung. Die Tandem-Massenspektrometrie (LC-MS/MS) ist solchen Einschränkungen nicht unterworfen. Die… Show more

“…The first method requires the regeneration of the columns after each analysis, the latter assays require complex sample preparation involving double derivatization (esterification of the carboxylic acid moiety and the acetylation of the amino group) procedure and expensive chiral capillary columns. In the developed high-performance liquid chromatographic (HPLC) methods vigabatrin has been analysed either alone [8][9][10][11] or with the other drugs such as gabapentin [12][13][14], haloperidol and amantadine [15]. Most of these methods involve the use of OPA derivatization and fluorimetric detection with isocratic [9,14] or gradient [10,12,13] system.…”
