APPLICATIONS
Mebendazole is a common benzimidazole anthelmintic used in the treatment of ascariasis, uncinariasis, oxyuriasis, trichuriasis and more than one worm infection at a time. It inhibits glucose uptake in the parasite, reulting in immobilization and death. It is a white to slightly yellow powder; insoluble in water, acid solutions, alcohol, ether and chloroform; freely soluble in formic acid. Chemical designation is 5-Benzoyl-2-benzimidazolecarbamic acid methyl ester.
