Application
Levamisole can regulate immune function, the main effect on T lymphocytes, to induce T cells early differentiation, mature into functional T cells, thus make T cells ht function is normal, can also strengthen the phagof macrophages, chemotaxis, to improve the activity of natural killer cells, produce endogenous interferon, improve the immune function make its normal, effectively prevent pneumonia disease progression, improve cough, lung sounds and other symptoms. In addition, after the immune function of children is weakened, through the use of levamidazole hydrochloride, it can increase the total complement content in the blood, especially the yield of IgG and IgA, so as to improve the immune effect of the respiratory tract, and play a role in virus resistance and bacterial infection prevention. Levamisole can not only regulate immunity, but also restore immunity. The abnormal humoral immune function can show bidirectional regulation, so that it tends to normal development, and help the low cellular immune function to return to normal.As an anthelmintic drug, it is suitable for the treatment of animal roundworm, hookworm, etc. Levamisole is about twice as active as a racemate and has less toxicity and side effects. Levamisole can paralyze the muscles of the worm. Mainly used for roundworm, hookworm, malworm infection.
