Mechanism of action

Oseltamivir phosphate is converted to its active form and inhibits influenza neuraminidase, an enzyme on the viral surface required for budding and release of new viral particles from host cells. By blocking neuraminidase activity, the drug prevents viral dissemination and reduces the duration and severity of influenza infection. The IV formulation provides direct systemic delivery for patients unable to take oral medication.
