Abstract: Abstract: A reversed phase ultra-performance liquid chromatography method was developed for the simultaneous quantitative determination of the systemically administered azoles voriconazole, posaconazole, isavuconazole, itraconazole and its metabolite hydroxy-itraconazole in plasma. The method involved a simple liquid–liquid extraction followed by ultra-performance liquid chromatography with an Acquity UPLC BEH Phenyl column and ultraviolet detection set at a wavelength of 260nm. The assay was validated over the concentration range of 0.050–10,000mg/l for all four azoles and one metabolite. The accuracies for the assay were 97–104%, inter- and intra-day coefficients of variation were <7.5% and extraction recoveries were 98% for voriconazole, posaconazole, isavuconazole and the internal standard (UK115794), and 79% and 88% for itraconazole and hydroxy-itraconazole respectively. This method proved to be simple, accurate, precise and fast and is currently in use in our laboratory for the quantitative analysis of these azoles for Therapeutic Drug Monitoring and pharmacokinetic research.
