Diclazuril is a triazine-based anticoccidial agent widely used in veterinary medicine to prevent and treat coccidiosis, a parasitic disease affecting the intestinal tract of animals, particularly poultry, rabbits, and livestock. It works by interfering with the development of the protozoan parasites, thereby reducing intestinal damage and improving animal health and productivity. Diclazuril was developed as a safer and more effective alternative to earlier anticoccidial drugs, with studies and synthesis emerging in the late 20th century. Its introduction marked a significant advancement in controlling coccidiosis, offering high efficacy with minimal toxicity and reduced risk of resistance. Today, diclazuril remains an important drug in animal husbandry, contributing to better growth performance and disease management in farm animals.
