Used as an active metabolite of albendazole in the treatment of parasitic worm infections. It contributes to the anthelmintic effect by inhibiting tubulin polymerization in susceptible parasites, leading to impaired glucose uptake and depletion of energy, ultimately causing parasite death. Effective against a range of gastrointestinal and tissue-dwelling helminths. Its presence in the body prolongs the therapeutic activity of albendazole, enhancing overall efficacy in treating infections such as neurocysticercosis and echinococcosis.
