Alben is a member of the Benzimidazole group of anthelmintic agents which is an ideal broad spectrum anthelmintic. Alben inhibits polymerization of tubulin causes loss of cytoplasmic microtubules that leads to impaired uptake of glucose, depletes glycogen stores, degenerative change in the endoplasmic reticulum and mitochondria & decrease production of ATP. It also inhibits the enzyme fumarate reductase which is a co-enzyme in many cellular oxidation-reduction reactions result no energy production and immobilization and death of parasites. Alben is a broad-spectrum anthelmintic. The principal mode of action for albendazole is by its inhibitory effect on tubulin polymerization which results in the loss of cytoplasmic microtubules.
