Description and Uses

Oseltamivir phosphate (Tamiflu) was launched in the US and Switzerland for the treatment of influenza infections by all common strain viruses. It is an oral anti-viral drug approved for the treatment of acute, uncomplicated influenza in patients 2 weeks of age and older whose flu symptoms have not lasted more than two days. This product is approved to treat Type A and B influenza; however, the majority of patients included in the studies were infected with type A, the most common in the U.S. Efficacy of Tamiflu in the treatment of influenza in subjects with chronic cardiac disease and/or respiratory disease has not been established.

Oseltamivir phosphate (Tamiflu) is a competitive neuraminidase inhibitor. The prodrug oseltamivir phosphate (Tamiflu) is itself not virally effective; however, once in the liver, it is converted by natural chemical processes, hydrolysed hepatically to its
