Used primarily in veterinary medicine as an antimicrobial and antiprotozoal agent, especially in poultry farming. It is effective against coccidiosis, a parasitic disease caused by Eimeria species that affects the intestinal tract of birds. Often administered in drinking water or feed, it helps control outbreaks and supports growth performance in infected flocks. Also used in combination with other drugs to enhance efficacy and prevent resistance development. Its use is regulated due to concerns about residues in food-producing animals.
