NA inhibitors include the medications zanamivir (Relenza) and oseltamivir (Tamiflu). Both drugs inhibit the viral protein, NA, which prevents the virus release from infected cells. The NA inhibitors are used to treat both influenza A and influenza B, although lower efficacy against in-fluenza B has been reported when using oseltamivir. All classes of drugs are most effective when administrated within 48 hours of the onset of symptoms and work to shorten the duration of the infection, as well as reduce complications.
