Evaluation of the efficacy and safety of a statin/caffeine combination against H5N1, H3N2 and H1N1 virus infection in BALB/c mice.

The development of novel antiviral drugs is necessary for the prevention and treatment of a potential avian influenza pandemic. The aim of this study was to evaluate the efficacy and safety of a novel statin/caffeine combination against H5N1, H3N2 and H1N1 virus infection in a murine model. In H5N1-, H3N2- and H1N1-infected BALB/c mice, 50μg statin/200μg caffeine effectively ameliorated lung damage and inhibited viral replication and was at least as effective as oseltamivir and ribavirin. The statin/caffeine combination also appeared to be more effective when administered preventatively rather than as treatment. These findings provide justification for further research into this novel antiviral formulation.
