Biochem/physiol Actions

Oseltamivir phosphate is an influenza viral neuraminidase inhibitor. Oseltamivir phosphate, an antiviral, is used clinically to treat influenza A and influenza B, and to prevent flu after exposure. Oseltamivir phosphate is hydrolyzed in the liver to its active form, oseltamivir carboxylate, which is an inhibitor of influenza viral neuraminidases essential for viral replication. Oseltamivir has a broad spectrum of activity against a range of influenza A and B subtypes with IC50 values for neuraminidases measured from less than 1 nM to approximately 30 nM, depending on the virus subtype.
