Antiparasitic refers to substances or treatments designed to eliminate or control parasites, which are organisms that live on or in a host and benefit at the host's expense. These parasites can include worms, protozoa, and ectoparasites like fleas and ticks. Antiparasitic medications are commonly used in both humans and animals to treat infections and prevent further complications. In agriculture, antiparasitic measures are crucial for protecting crops and livestock from harmful parasites. Farmers often use antiparasitic drugs to ensure the health of their animals and improve productivity. By controlling parasitic infections, these treatments help maintain a balanced ecosystem and support food security.
