Used primarily as an anthelmintic in veterinary medicine, effective against a range of gastrointestinal parasites including roundworms, hookworms, and whipworms in animals such as dogs, cats, and livestock. It works by inhibiting tubulin polymerization in parasite cells, disrupting their microtubule structure and leading to paralysis and death of the parasites. Commonly administered orally in the form of tablets or suspensions, it is valued for its broad-spectrum activity and safety profile at recommended doses. Often included in deworming protocols for puppies and kittens due to its efficacy and low toxicity.
