New methodology for the extraction and analysis of the anthelmintic fenbendazole and its metabolites from plasma, urine, liver homogenates, and feces from several animal species is presented. Quantitation of fenbendazole and its metabolites was conducted by high-pressure liquid chromatography using ultraviolet detection at 290 nm. The combined extraction and analysis procedures give excellent recoveries in all of the different biological matrices examined. High specificity, low limits of detection, and excellent linearity, accuracy, and inter- and intrasample variability were also obtained. The study of fenbendazole pharmacokinetics in vitro and in vivo should be greatly enhanced through the utilization of these methods.
