Baloxavir marboxil is an antiviral prodrug used in the treatment of influenza A and B. It inhibits the cap-dependent endonuclease activity of the viral polymerase, blocking viral replication. Approved and currently used for the treatment of acute, uncomplicated influenza in otherwise healthy adults and adolescents.
Pharmacokinetics
Pharmacokinetic parameters reported for healthy adult subjects following a single oral dose.
