Mechanism of action

Oseltamivir (Tamiflu) is a prodrug that is converted in the body to its active form, which binds to and inhibits influenza neuraminidase. This enzyme normally cleaves sialic acid receptors on host cells, allowing newly formed virus particles to escape. By blocking this step, the drug traps viral particles on the cell surface and reduces transmission to neighboring cells, thereby shortening infection duration and reducing symptom severity.
