Used as an anthelmintic in veterinary medicine, effective against a broad spectrum of gastrointestinal parasites including roundworms, hookworms, and whipworms in dogs and cats. It is commonly formulated in combination with other active ingredients to enhance efficacy. Febantel works as a prodrug, metabolizing into active compounds that disrupt parasite nervous system function, leading to paralysis and death. Its use supports control of mixed parasitic infections in companion animals.
