Albendazole is a benzimidazole anthelmintic, active against most nematodes and some cestodes. It is used in the treatment of intestinal nematode infections and in higher doses in the treatment of hydatid disease. Albendazole exhibits vermicidal, ovicidal, and larvicidal activity. The principal mode of action of Albendazole is its inhibitory effect on tubulin polymerization, which results in the loss of cytoplasmic microtubules.
Albendazole is a broad spectrum benzimidazole anthelminthic drug. In addition to its vermicidal properties, it has both ovicidal and larvicidal activities.
