Oseltamivir

Patent Granted Oseltamivir INN /ɒsəlˈtæmɨvɪər/, marketed under the trade name Tamiflu, is an antiviral licensed to prevent or slow the spread of influenza A and influenza B (flu) virus between cells in the body by stopping the virus from chemically cutting ties with its host cell.[2] The drug is taken orally in capsules or as a suspension. 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.
