  • Oxfendazole is the sulfoxide form of fenbendazole which is a broad spectrum benzimidazole anthelmintic. Target: AntiparasiticOxfendazole is the sulfoxide form of fenbendazole, a broad spectrum benzimidazole anthelmintic. Its main use is for protecting livestock against roundworm, strongyles and pinworms.[1]. Pigs in the treated group received Oxfendazole orally at 30 mg/kg dose. At five days post-treatment, animals were sacrificed and the clinical efficacy of the Oxfendazole treatment was established following the currently available WAAVP guidelines for a controlled efficacy test. None of the animals involved in this experiment showed any adverse events during the study. Oxfendazole treatment given as a single 30 mg/kg oral dose showed a 100% efficacy against all the nematode parasites present in the three experiments. In conclusion, under the current experimental conditions, Oxfendazole orally administered to naturally parasitized piglets at a single dose of 30 mg/kg was safe and highly efficacious (100%) against adult stages of A. suum, Oesophagostomum spp., T. suis and Metastrongylus spp [1].
