Clopidol is primarily used as an anticoccidial agent in veterinary medicine. It is effective in preventing and treating coccidiosis, a parasitic disease that affects the intestinal tracts of animals, particularly poultry and livestock. By inhibiting the development of coccidia parasites, clopidol helps maintain the health and productivity of animals, ensuring better growth rates and reduced mortality. It is often incorporated into animal feed or drinking water for easy administration. Additionally, clopidol is valued for its ability to control coccidiosis without causing significant resistance, making it a reliable option in the management of this disease in animal husbandry.
