Peramivir is an experimental antiviral drug being developed by BioCryst Pharmaceuticals for the treatment of influenza.

Peramivir is a neuraminidase inhibitor, acting as a transition-state analogue inhibitor of influenza neuraminidase and thereby preventing new viruses from emerging from infected cells.

The development of peramivir is supported by the US Department of Health and Human Services as part of the US government's effort to prepare against the threat of an influenza pandemic.[1]

The drug has had a long history. An oral formulation was abandoned by Johnson and Johnson due to poor bioavailability.[2] BioCryst Pharmaceuticals is now developing a injectable version, in partnership with Green Cross Pharmaceuticals in South Korea and with Shionogi Pharmaceuticals in Japan. The drug is in Phase II studies.[3][4]

Use in treating Influenza A (H1N1) "Swine Flu"

In October 2009, it was reported that the experimental antiviral drug Peramivir had been effective in treating serious cases of swine flu.[5] On October 23, the U.S. Food and Drug Administration (FDA) issued an Emergency Use Authorization for Peramivir, allowing the use of the drug in intravenous form for hospitalized patients only in cases where the other available methods of treatment are ineffective or unavailable;[6] for instance, if Tamiflu resistance develops and a person is unable to take Relenza via the inhaled route. Peramivir is currently the only intravenous option for treating swine flu.

In Tamiflu resistant cases, peramivir is not recommended due to reduced sensitivity conferred by Tamiflu resistance.[7]

Biocryst has donated 1200 courses of treatment to the US department of Health and Human Services.[8]
