Description :Triazavirin sodium (TZV, Riamilovir), a nucleoside analogue of nucleic acid, is a broad-spectrum and potent antiviral agent. It was originally developed as a potential treatment for pandemic influenza strains such as H5N1, and most of the testing that has been done has focused on its anti-influenza activity. However triazavirin has also been found to have antiviral activity against a number of other viruses including Tick-borne encephalitis virus, and Forest-Spring Encephalitis virus,[6] and is also being investigated for potential application against Lassa fever and Ebola virus disease. In February 2020, testing of triazavirin was started against SARS-CoV-2. Triazavirin works by inhibiting the synthesis of viral RNA and DNA and replication of genomic fragments. Triazavirin is also an effective protective agent on the transmission stage of influenza.
