  Abstract Therapeutic drug monitoring of triazoles is widely used in clinical practice to optimize therapy, especially in those patients who need antifungal treatment as co-medications. Here it is described development and validation of a new chromatographic method in order to quantify voriconazole and posaconazole in human plasma by ultraviolet detection. After liquid extraction of analytes from plasma using acetonitrile, samples are evaporated to dryness and then reconstituted in mobile phase for chromatographic separation. Analysis is achieved on C18 reverse phase column and eluate is monitored at 250 nm. Mobile phase consisted of 35% water, 15% methanol, 50% acetonitrile. Flavone was used as internal standard; retention times (minutes) were, respectively, for voriconazole 3.9, posaconazole 7.9, flavone 7.1. Accuracy and variability were assayed by inter- and intra-day validation, c.. View More»
