PRODUCT INTRODUCTION
description
Levamisole is a 6-phenyl-2,3,5,6-tetrahydroimidazo[2,1-b][1,3]thiazole that has S configuration. It is used (generally as the monohydrochloride salt) to treat parasitic worm infections in pigs, sheep and cattle and was formerly used in humans as an adjuvant to chemotherapy for the treatment of various cancers. It is also widely used as an adulterant to coccaine. It has a role as an antinematodal drug, an antirheumatic drug, an immunomodulator, an immunological adjuvant and an EC 3.1.3.1 (alkaline phosphatase) inhibitor. It is an enantiomer of a dexamisole.
