Abstract:
A specific and selective high-performance liquid chromatography (HPLC) technique that requires few manipulations, and is readily adaptable to analysis for a large series of samples, has been developed for the determination of the concentration of the anticancer drug doxorubicin (DXR) in rat serum and tissues. The biological samples were efficiently deproteinised and resolved from a reversed-phase nucleosil C18 column with fluorescence detection. The validation study of the proposed method was successfully carried out in an assay range of between 5 and 5000 ng/ml and was subsequently implemented in a pharmacokinetic study of DXR in Wistar rats that were treated by intravenous administration of the drug.
