Aim: Aim of this research was to develop and validate a simple, efficient and reproducible high performance liquid chromatography method to measure phenytoin concentrations in human plasma

Study Design: Linearity, selectivity, sensitivity, accuracy and precision of the analytical methods were validated according to ICH guidelines.

Methodology: The method employed a Phenomenex C18 column kept at 25ºC. The mobile phase consisted of a 0.05 M potassium dihydrogen phosphate buffer solution (pH 2.8) and methanol in a ratio of 60:40, respectively. The flow rate of the mobile phase was 0.7 mL/min. Phenytoin was detected at a wavelength of 250 …
