An anthelmintic is a medication that is used to treat parasitic worm infestations in animals. This comprises both flat and round worms, such as flukes (trematodes) and tapeworms (cestodes). These medications block metabolic activities that are essential to the parasite but not to the host. The intestines do not well absorb some anthelmintics. As a result, the parasite is exposed to the medicine at a far higher concentration than the host body. Neuromuscular coordination, energy production, and microtubular integrity are all important in the worm's life cycle. Antihelmintic medications are usually taken orally because this is the most stable way of administration.
