Influenza Virus Resistance to Neuraminidase Inhibitors: Implications for Treatment.

Oseltamivir and Zanamivir are the two main Neuraminidase inhibitors used for the treatment of Influenza. Oseltamivir resistance has been identified in non-pandemic influenza viruses, as well as H1N1 pandemic Influenza A viruses. Resistance is associated with increased morbidity, and poorer outcomes in severely immunocompromised hosts. Newer neuraminidase inhibitors, increased vaccination and combination therapy may be alternatives for the treatment of Influenza in this setting. [ABSTRACT FROM AUTHOR]
