Albendazole

About Albendazole
Benzimidazole derivative, Antihelmintic.
Mechanism of Action of Albendazole
Albendazole is used as a broad spectrum anthelminthic which acts by blocking glucose uptake in the parasite and depletion of its glycogen stores. It causes selective degeneration of cytoplasmic microtubules in intestinal and tegmental cells of intestinal helminthes and larvae. Intracellular microtubules in the cells of the worm are gradually lost. The drug binds to beta tubulin of susceptible worms with high affinity and inhibits its polymerization. Single dose treatment is effective against Ascaris, Hook worm, and Enterobius. It is superior to Mebendazole for treatment of Hydatid worm, and strongyloidosis. It is also used in the treatment of tape worms, Filariasis, and Trichuriasis.
