It has a moderate immunomodulatory effect. It has interferon-inducing activity, stimulates humoral and cellular immune responses, phagocytic function of macrophages, increases the body's resistance to viral infections. Reduces the incidence of complications associated with a viral infection, as well as exacerbations of chronic bacterial diseases.

Therapeutic efficacy in viral infections is manifested in a decrease in the severity of general intoxication and clinical phenomena, and a reduction in the duration of the disease. Refers to low-toxic drugs. Does not have any negative effects on the human body when taken orally in recommended doses.
