The methods of treatment by using the stimulators of the non-specific resistance system have been growing even more topical. Drugs based on interferon (INF) and its inducers belong to the group. IFN is of key importance in the regulation of antiviral immunity. The use of IFN inducers can be referred to as the most promising approach to enhancing and activating the body resistance mechanisms. The advantages of IFN inducers before IFN drugs, a wide spectrum of antiviral effects, compatibility with many pharmaceuticals, good tolerability by patients and effectiveness in different administration modes served as a basis for designing a new class of antiviral drugs--IFN inducers. A lot of experimental medical-and-biological research was made to evaluate the efficiency of IFN inducers in influenza. They were shown to possess a pronounced therapeutic-and-preventive action in experiment and clinical trials. Synthetic and natural dsRNA belong to IFN inducers. Multiple research made in cell culture and with experimental animals demonstrated a high interferon-inducing and antiviral activity of double-stranded RNA against influenza virus. A number of dsRNA-based IFN inducers are permitted for clinical use. Data obtained in clinical trials of such inducers are indicative of their pronounced therapeutic-and-clinical effect. Hence, the IFN inducers having different structures and origins can be regarded as promising in the treatment and prevention of influenza and acute respiratory viral diseases.
