How Oseltamivir works
Oseltamivir is an antiviral medicine.
It works by blocking the action of an enzyme called neuraminidase, which is present on the surface of the influenza virus. By inhibiting neuraminidase, Oseltamivir prevents new viral particles from being released. This effectively stops the virus from spreading within the body.
