Luxabendazole is a benzimidazole carbamate broad-spectrum anthelmintic agent. It has proved to be effective against immature and adult stages of the major gastrointestinal nematodes, cestodes, and trematodes.
5-hydroxy Thiabendazole (5-OH TBZ) is a major metabolite of the anthelmintic thiabendazole . Unlike thiabendazole, 5-OH TBZ has no effect on the growth of third-stage A. caninum larvae.
Fenbendazole sulfone is a minor metabolite of the anthelmintic fenbendazole . Fenbendazole undergoes oxidation to form oxfendazole, which is further oxidized to form fenbendazole sulfone.
