Antiflu, also known as oseltamivir, is an antiviral medication used to treat and prevent influenza (flu) infections. It belongs to a class of drugs called neuraminidase inhibitors. Influenza viruses have two main surface proteins: hemagglutinin (H) and neuraminidase (N). Hemagglutinin helps the virus attach to and enter host cells, while neuraminidase allows newly formed virus particles to be released from infected cells, facilitating the spread of the virus within the body. Antiflu works by inhibiting the activity of the neuraminidase enzyme, preventing the release of newly formed virus particles from infected cells. By doing so, it helps to reduce the spread of the virus within the body, limiting the severity and duration of flu symptoms. Antiflu is most effective when started within 48 hours of the onset of flu symptoms. It can also be used preventatively in certain situations, such as during flu outbreaks or for individuals at high risk of complications from the flu. Overall, antiflu plays a vital role in the management of influenza infections by targeting a key step in the virus's life cycle.
