Final answer:
Fenbendazole is a parasiticide, a class of drugs used to treat parasitic infections, working specifically against certain nematodes by inhibiting microtubule formation and glucose uptake.
Step-by-step explanation:
An example of a parasiticide is Fenbendazole. This class of drug is designed to target parasitic organisms. They are used to treat infestations and infections caused by a variety of parasites, including certain types of nematodes and other multicellular parasites. Treating parasitic nematode infections, such as those caused by hookworms, Trichinella, Ascaris, and filariasis causing agents, often requires the use of antihelminthic drugs. Fenbendazole is one such antihelminthic drug that belongs to the benzimidazole group and works by disrupting the microtubule structures within intestinal cells of the worms, leading to a loss of glucose uptake and their ultimate demise. Antihelminthic drugs, including fenbendazole, are crucial in both human and veterinary medicine for the treatment and control of parasitic infections.
