What is the primary mechanism of action of Tamiflu?

Tamiflu, also known as oseltamivir, primarily functions as an antiviral medication. Its mechanism of action involves inhibiting the influenza virus neuraminidase enzyme, which is crucial for the virus's replication and spread within the respiratory tract. By blocking this enzyme, Tamiflu effectively prevents the release of new viral particles from infected cells, thereby limiting the infection's severity and duration. This makes Tamiflu especially useful in treating and preventing influenza infections. The focus of Tamiflu's action is specifically on viral pathogens, distinguishing it clearly from medications that target bacterial, fungal, or inflammatory conditions.
