The FDA has approved Rapivab for the treatment of influenza infection in adults.
Rapivab is an inhibitor of influenza virus neuraminidase, an enzyme that releases viral particles from infected cells. Neuraminidase inhibitors are commonly used to treat flu infection. Rapivab is the first neuraminidase inhibitor approved for intravenous (IV) administration and is administered as a single IV dose. It is intended for patients 18 years and older who have acute uncomplicated influenza and have shown symptoms of flu for no more than two days.
