Used as an antiparasitic agent in veterinary medicine to control internal and external parasites in livestock and companion animals. Effective against nematodes and arthropods, including species resistant to other classes of dewormers. Commonly administered in cattle, sheep, goats, and dogs to prevent infestations. Also used in the treatment of heartworm in dogs and has shown potential in controlling parasitic mites in poultry and swine. Its long-lasting effect allows for less frequent dosing compared to other parasiticides.
