The aim of this study was to develop and validate a high-performance liquid chromatographic-tandem mass spectrometric (LC-MS/MS) method for analysis of the amiridine in human plasma. The analyte and internal standard (IS), zolpidem, were extracted from human plasma by solid phase extraction (SPE with SOLA cartridges) and separated on a Zorbax SB-C18 column using methanol and 0.2% formic acid in water as mobile phase. Detection was performed using an electrospray ionization source and mass

The assay was linear over the concentration range 0.5–200 ng/mL with the lowest limit of quantification (LLOQ) of 0.5 ng/mL. The method also afforded satisfactory results in terms of the sensitivity, specificity, precision (intra- and interday %), accuracy, recovery, and the stability of the analyte under various conditions. The method can be successfully applied to pharmacokinetic studies.
