Description of the properties of double-stranded ribonucleic acid (dsRNA)

The original active substance dsRNA was developed by the Latvian Academy of Sciences as a high molecular weight inducer of natural interferon. The clinical efficacy of dsRNA was studied in various clinics and institutes in Latvia and the former USSR in the 80s of the last century. It has been proven that it has a pronounced immunomodulatory effect, stimulates T-cell and humoral immunity2. A distinctive feature of dsRNA is that interferon is detected in human serum within 4-8 hours after applying the cream3. DsRNA is used as a therapeutic and prophylactic agent for herpes diseases, influenza, adenovirus and rhinovirus infections, for hepatitis B, as well as in immunotherapy of tumors. Thanks to dsRNA, it became possible to avoid the disease by strengthening the immune system (prevention) 4.
