Trichuriasis is treated with which of the following medications?

Trichuriasis, an infection caused by the whipworm Trichuris trichiura, is effectively treated with mebendazole. This medication functions as an anthelmintic, specifically inhibiting the uptake of glucose and other nutrients in the helminth, leading to the depletion of their energy stores and eventual death. Mebendazole is favored due to its safety profile and efficacy in killing the adult worms that reside in the intestinal lumen.

While other medications such as albendazole also treat helminth infections, mebendazole is particularly well-documented for the treatment of trichuriasis. Pyrantel pamoate is effective against other types of intestinal worms but does not effectively eradicate whipworms. Doxycycline, an antibiotic, has no role in the treatment of trichuriasis as it does not target helminths. Thus, mebendazole is the preferred choice for treating trichuriasis owing to its specific action against this particular parasite.
