Flubendazole; Uses, Dosage, Side Effects, Interactions, Pregnancy

Flubendazole is an anthelmintic. Its brand name is Flutelmium which is a paste manufactured by Janssen Pharmaceutica N.V. used by veterinarians for protection against internal parasites and treat worm infection in humans.

Mechanism of Action of Flubendazole

The molecular mode of action of all benzimidazoles, including flubendazole, consists in binding to tubulin, a structural protein of microtubules. Flubendazole is a benzimidazole compound that is used as an antiparasitic and anti-cancer agent. It has been shown to be an effective anthelminthic chemical by inhibiting tubulin synthesis and disrupting cytoskeleton formation. Flubendazole has also been shown in vivo to be a strong anti-cancer compound by the same mechanism and is potent toward vinblastine resistant cell lines. These microtubules are important organelles involved in the motility, the division and the secretion processes of cells in all living organisms. In the worms, the blocking of microtubules perturbs the uptake of glucose, which eventually empties the glycogen reserves. This blocks the whole energy management mechanism of the worms that are paralyzed and die or are expelled.

Since cell division is also disturbed, worm egg production and development is also blocked by benzimidazoles, i.e. most of them also have an ovicidal effect.
