What is Baloxavir Marboxil Used For?
Baloxavir marboxil is an antiviral medication used to treat acute uncomplicated influenza (flu) in patients aged 12 years and older who have been symptomatic for no more than 48 hours. It is also used for post-exposure prophylaxis to prevent influenza in individuals 12 years of age and older after close contact with an infected person. [1]
How Does Baloxavir Marboxil Work?
Baloxavir marboxil functions by inhibiting the cap-dependent endonuclease activity of the influenza virus. This enzyme is crucial for viral replication, as it cleaves host cell mRNA to generate primers for viral RNA synthesis. By blocking this enzyme, baloxavir marboxil prevents the virus from making copies of itself. [1]
