Description

Oseltamivir phosphate is an ethyl ester prodrug requiring ester hydrolysis for conversion to the active form, oseltamivir carboxylate. Oseltamivir carboxylate is an inhibitor of influenza virus neuraminidase affecting release of viral particles. Oseltamivir is a well tolerated orally active neuraminidase inhibitor which significantly reduces the duration of symptomatic illness and hastens the return to normal levels of activity when initiated promptly in patients with naturally acquired influenza.

Sample Use Guides

In Vivo Use Guide
The recommended oral dose of TAMIFLU (oseltamivir phosphate) for treatment of influenza in adults and adolescents 13 years and older is 75 mg twice daily for 5 days. Treatment should begin within 2 days of onset of symptoms of influenza.
Route of Administration: Oral
In Vitro Use Guide
Oseltamivir also showed moderate antiviral activity in Madine-Darby canine kidney cells of about 83% against influenza A/HK (H3N2) virus at the concentration of 100 μg/ml.
