Endectocides are a class of antiparasitic drugs that target both internal and external parasites in animals. They are commonly used in veterinary medicine to treat infections caused by worms, mites, and other parasites. These medications work by disrupting the nervous system of the parasites, leading to their elimination from the host. One of the most well-known endectocides is ivermectin, which is effective against a wide range of parasites. These drugs are often administered as oral tablets, injections, or topical treatments, making them versatile options for managing parasitic infections in livestock and pets.
