Oseltamivir

Oseltamivir INN ( /ɒsəlˈtæmɨvɪər/), an antiviral drug, slows the spread of influenza (flu) virus between cells in the body by stopping the virus from chemically cutting ties with its host cell; median time to symptom alleviation is reduced by 0.5–1 day. The drug is sold under the trade name Tamiflu, and is taken orally in capsules or as a suspension. It has been used to treat and prevent influenza A virus and influenza B virus infection in over 50 million people since 1999.[citation needed]

Oseltamivir is a prodrug, a (relatively) inactive chemical which is converted into its active form by metabolic process after it is taken into the body. It was the first orally active neuraminidase inhibitor commercially developed.[citation needed] It was developed by C.U. Kim, W. Lew, and X. Chen of US-based Gilead Sciences, and is currently marketed by Hoffmann–La Roche (Roche). In Japan, it is marketed by Chugai Pharmaceutical Co., which is more than 50% owned by Roche.

As of December 2010[update], the World Health Organization (WHO) reported 314 samples of the prevalent 2009 pandemic H1N1 flu tested worldwide have shown resistance to oseltamivir.
