Triclabendazole sulfoxide is primarily used in veterinary medicine as an antiparasitic agent, particularly effective against liver flukes in livestock such as sheep, cattle, and goats. It works by disrupting the energy metabolism of the parasites, leading to their death. This compound is particularly valued for its ability to target both immature and mature stages of the fluke, providing comprehensive treatment and prevention of infections. Its application helps in improving animal health, enhancing productivity, and reducing the risk of transmission to humans in areas where zoonotic infections are a concern. Additionally, it plays a crucial role in controlling outbreaks of fascioliasis, a disease caused by liver flukes, which can significantly impact agricultural economies.
