Used in veterinary medicine as an antiparasitic agent to control internal and external parasites in livestock such as cattle, sheep, and swine. Effective against nematodes, lungworms, gastrointestinal roundworms, and ectoparasites like mites and lice. Administered via injection or pour-on formulations, it provides broad-spectrum control and helps improve animal health and productivity. Also used in some countries for parasite control in companion animals. Its long residual activity allows for sustained protection after a single dose.
