Triazavirin
Identification
- Name
- Triazavirin
- Accession Number
- DB15622
- Description
Triazavirin is a guanine nucleotide analog antiviral originally developed in Russia that has shown efficacy against influenza A and B, including the H5N1 strain.1,2,4 It appears that Triazavirin has shown promise in reducing influenza disease severity and associated complications.5 Given the similarities between SARS-CoV-2 and H5N1, health officials are investigating Triazavirin as an option to combat SARS-CoV-2, the coronavirus responsible for COVID-19.2
