Sample was extracted from 0.5mL heparinized plasma by a simple liquid-liquid extraction method and analyzed on a C18 column with a mobile phase of acetonitrile-water (78:22,v/v,0.1% acetic acid). Detection was carried out by positive elevtrospray ionization (ESI) in multiple reactions monitoring (MRM) mode of 300.3-->199.2 (m/z) for hydrocodone and 341.2-->107.2 (m/z) for canrenone (I.S.), respectively. A good linearity was obtained from 0.5 to 60 ng.mL(-1) and the lower limit of quantification (LLOQ) was 0.1ng.mL(-1). Compared to an existing method, the extraction method, internal standard and chromatographic conditions were modified and the cost of a large amount of samples determination was decreased obviously. The method was successfully applied to the pharmacokinetic and bioequivalence studies in healthy Chinese volunteers. | | Language | ENG | | Pub Type(s) | JOURNAL ARTICLE
