How does Baloxavir Marboxil (Xofluza) work?
Baloxavir Marboxil is a prodrug that is converted by hydrolysis to baloxavir. It is the active form that exerts anti-influenza virus activity. Baloxavir inhibits the endonuclease activity of the polymerase acidic (PA) protein. It is an influenza virus-specific enzyme in the viral RNA polymerase complex required for viral gene transcription. It results in the inhibition of influenza virus replication. Viruses with reduced susceptibility to baloxavir have amino acid substitutions in the PA protein.

Baloxavir Marboxil (Xofluza) is an antiviral PA endonuclease inhibitor. This is for oral administration and is supplied as white to light yellow film-coated tablets. This medication works differently by targeting the flu at its source to stop viral replication. In October 2018, the U.S. Food and Drug Administration (FDA) approved this treatment.
