A rapid and robust UHPLC-DAD method for the quantification of amphotericin B in human plasma

Amphotericin B is an antifungal drug widely used in Intensive Care Units. Therapeutic drug monitoring (TDM) of amphotericin B is recommended for the assessment of toxicity surveillance and treatment optimization. In this paper we described the development and validation of a new Ultra High Performance Liquid Chromatography coupled to Diode Array Detection (UHPLC-DAD) method for the quantification of Amphotericin B in 200μL human plasma over a wide range of concentrations (0.125-10mg/L). The new method has been validated following international guidelines on bioanalytical method validation and showed high selectivity, high accuracy and precision and high process efficiency. The new UHPLC-DAD method that we describe is robust, rapid, cost effective and suitable for application to the routine TDM analyses.
