Abstract
A simple and reliable new HPLC method with UV detection has been developed and validated for simultaneous determination of mitotane and its two metabolites DDA and DDE. Method development was carried out utilizing systematical approach of the design of experiments (DoE) methodology. For estimation of factors influence on selected chromatographic responses and definition of the optimal chromatographic conditions, Box-Behnken experimental design was applied. The defined optimal separation conditions were: column Restek Ultra Aqua C-18 with pre-column Restek Ultra Aqua C-18 operating at temperature 35 degrees C; mixture of acetonitrile and 0.5% formic acid as mobile phase with 1.2mL min(-1) flow rate and detection at 230nm. As sample preparation method, liquid-liquid extraction was chosen. Method was fully validated and LOQ and LOD were experimentally determined. Finally, method was successfully applied for determination of mitotane and its metabolites in plasma samples of patients with a...drenocortical carcinoma.
