Oseltamivir (Overview)

The brand name is tamiflu (oseltamivir). It is a prodrug, which means it is inactive until metabolized by a person's body into the active form. It blocks neuraminidase, an enzyme in influenza virus; by doing this, it prevents the flu virus from detaching from the host cell and slows the spread of the virus. It comes in a tablet form, as well as a suspension.
