Albendazole is a broad-spectrum anthelmintic medication used to treat a variety of parasitic worm infestations. It works by inhibiting the polymerization of tubulin into microtubules, which impairs essential cellular functions in parasites, leading to their death. It is effective against roundworms, tapeworms, and flukes, and is often used in both intestinal and tissue-based parasitic infections, including neurocysticercosis and hydatid disease.
