Zanamivir, marketed under the brand name Relenza, is an FDA- and EMA-approved antiviral drug used for the treatment and prevention of Influenza A and B. As a neuraminidase inhibitor, Zanamivir prevents the release of new virus particles from infected cells, reducing flu severity and duration when started within 48 hours of symptoms. It is administered via oral inhalation using a Diskhaler, with each dose delivering 10 mg (two 5 mg blisters). Zanamivir is approved for use in adults and children (≥7 years for treatment, ≥5 for prevention). Relenza offers a localized delivery option with minimal systemic side effects.
