Levamisole Hydrochloride (Levamisole HCl), is an anthelmintic
(anti-worm) agent commonly used in large livestock such as cattle,
pigs and sheep. In ***1 it was found to have immunostimulatory
properties and investigation into its use in humans began to
expand. Currently, Levamisole HCl is used in humans for diseases
related to imbalances in the regulation of immune responses or
deficiencies of the immune system, including autoimmune diseases,
chronic and recurrent diseases, chronic infections and cancer. It
has beneficial effects on host defense mechanisms and restores
depressed immune responses in animals and humans. Another
interesting use of levamisole in humans is as a treatment for
common warts (verruca vulgaris).
