According to Reuters, Relenza joins Roche AG's Tamiflu as the only other drug with Food and Drug Administration clearance for both prevention and treatment of the flu.
The report notes, countries around the world have been stockpiling both drugs for use in case the H5N1 avian flu virus changes to a form that spreads easily among people and sparks a global pandemic.
Dr. Steven Galson, director of the FDA's Center for Drug Evaluation and Research says, in the report, "This approval is a welcome addition to the available defenses against the flu."
