Milbemycin oxime is widely used in veterinary medicine as an antiparasitic agent. It is effective against a broad spectrum of internal and external parasites in animals, including heartworms, roundworms, hookworms, and mites. Commonly administered orally to dogs and cats, it helps prevent heartworm disease and treats existing intestinal parasite infections. Additionally, it is used in livestock to control parasitic infestations, improving animal health and productivity. Its mechanism of action involves disrupting the nervous system of parasites, leading to paralysis and death. Milbemycin oxime is often combined with other medications to enhance its efficacy and provide comprehensive parasite control.
