Used primarily as an anthelmintic in veterinary medicine, particularly for cats and dogs. It is effective against a broad spectrum of gastrointestinal nematodes, including resistant strains such as hookworms and roundworms. Its mechanism involves acting on presynaptic latrophilin receptors and calcium-activated potassium channels in parasites, leading to paralysis and death of the worms. Due to its unique mode of action, it is valuable in managing parasites that have developed resistance to other anthelmintic classes like benzimidazoles, macrocyclic lactones, or tetrahydropyrimidines. Often combined with other agents such as praziquantel to provide broad-spectrum deworming coverage, including cestodes. Also under investigation for potential use in human medicine, especially for drug-resistant parasitic infections.
