Levamisole Hydrochloride Pagoda Sugar

This product is the levorotatory form of tetramisole, which can selectively inhibit succinate dehydrogenase in the muscles of the worm, so that fumaric acid cannot be reduced to succinic acid, thereby affecting the anaerobic metabolism of the muscles of the worm and reducing energy production. When the worm comes into contact with it, it can depolarize the nerves and muscles, and the muscles will continue to contract and cause paralysis; the drug's cholinergic effect is conducive to the excretion of the worm. Its activity is about 1 to 2 times that of tetramisole (racemic form), but its toxic side effects are lower. In addition, the drug may have an inhibitory effect on the microtubule structure of the worm. Levamisole also has immune regulation and immune excitation functions.
