Anthelmintics are medications used to treat infections caused by parasitic worms, known as helminths. These drugs work by either killing the worms or inhibiting their growth and reproduction. Common types of helminths include roundworms, tapeworms, and flukes, which can infect humans and animals, leading to various health issues. These medications are essential in both human and veterinary medicine. They help prevent and control diseases caused by these parasites, improving overall health and well-being. Some widely used anthelmintics include albendazole and ivermectin, which are effective against a range of worm infections.
