Which anthelmintic drug kills parasites by blocking their uptake of glucose?

Mebendazole is an anthelmintic drug that works by inhibiting the formation of microtubules in parasitic worms, which ultimately disrupts their ability to absorb glucose effectively. This interference with glucose uptake leads to the depletion of the parasite's energy stores, causing them to die. Mebendazole is specifically used against a variety of nematodes and is known for its effectiveness in treating infections such as ascariasis, hookworm, and enterobiasis.

While other anthelmintics also serve important roles in treating parasitic infections, their mechanisms of action differ significantly from that of mebendazole. For instance, albendazole has a similar function but has additional effects, praziquantel primarily acts by causing paralysis and damaging the integument of the worms, and levamisole is more often used as an immunomodulator in animals and acts as a neuromuscular blocking agent. The unique mechanism of mebendazole focusing on glucose uptake makes it the right answer in this context.
