Pharmacology

Oseltamivir is a prodrug of oseltamivir carboxylate. Oseltamivir carboxylate inhibits neuraminidase (sialidase), a viral surface enzyme which is responsible for the replication and infectivity of influenza virus A and B, thereby preventing the release of viruses from infected cells.

There is no evidence for efficacy of Oseltamivir Phosphate in any illness caused by agents other than influenza viruses Types A and B. Efficacy of Oseltamivir Phosphate in patients who begin treatment after 40 hours of symptoms has not been established.
