Used primarily as a veterinary anthelmintic, especially effective against liver flukes in ruminants such as cattle and sheep. It targets adult forms of *Fasciola hepatica*, helping control fascioliasis, a parasitic infection that affects the liver. Commonly administered orally in tablet or drench form, it is valued for its high efficacy and low toxicity in target animals. Often included in combination products with other dewormers to broaden the spectrum of activity against gastrointestinal parasites. Not approved for human use.
