Antiviral strategies against H5N1: current options and emerging therapeutics. (PubMed, Infection) - "This article provides a comprehensive, up-to-date overview of antiviral agents with established or investigational activity against H5N1, including both globally approved drugs and regionally licensed compounds, such as arbidol and triazavirin in Russia and laninamivir and favipiravir in Japan...The recent regulatory approvals of onradivir, suraxavir marboxil, and ZX-7101A in China are highlighted, along with emerging antivirals in advanced development...Challenges persist around resistance monitoring, access to novel therapies, and regulatory harmonization. Expanding the antiviral armamentarium through accelerated evaluation and integration of both traditional and innovative compounds will be essential to pandemic preparedness and effective H5N1 outbreak response."
