title: Assay of ambroxol in biological fluids by capillary gas-liquid chromatography.
abstract: A sensitive and rapid method for the determination of ambroxol in biological fluids is described. It comprises a single extraction step, derivatization and selective determination with capillary gas-liquid chromatography (in split-mode) and electron-capture detection. The limit of quantification in plasma is ca. 3 ng/ml. The method is applied to the pharmacokinetics of ambroxol in humans.
