Fenbendazole is a broad-spectrum anthelmintic medication widely used in veterinary medicine to treat intestinal worm infections. It belongs to the benzimidazole class of drugs and is effective against a variety of gastrointestinal parasites, including roundworms, hookworms, whipworms, and certain tapeworms.
Fenbendazole UK works by targeting the internal cellular structure of parasites. Specifically, it binds to a protein called beta-tubulin within the worm’s cells. Beta-tubulin is essential for forming microtubules, which are important structural components that help maintain cell shape and support vital processes such as nutrient absorption and cell division. When Fenbendazole binds to beta-tubulin, it disrupts the formation of microtubules.
This disruption prevents the parasite from absorbing glucose, which is its primary source of energy. Without glucose, the worm cannot produce enough energy to survive. As a result, its energy reserves become depleted, leading to gradual paralysis and death. Because the drug interferes with basic metabolic functions rather than immediately killing the parasite, the process may take a few days.
One of the advantages of Fenbendazole is its selective action. It has a higher affinity for parasite cells than for mammalian cells, making it generally safe when used at recommended dosages. After administration, the dead or weakened worms are expelled from the host’s body through normal bowel movements.
Overall, Fenbendazole is considered a reliable and effective treatment for controlling intestinal worm infections in animals when used under proper veterinary guidance.
