What is the dosage form of Baloxavir marboxil (Xofluza)?

Baloxavir marboxil, marketed as Xofluza, is formulated as a single oral dose medication. This is significant for a couple of reasons. First, the convenience of a single-dose regimen enhances patient compliance, making it easier for individuals to complete their treatment quickly and effectively, especially during periods of high flu incidence. Second, the mechanism of action allows it to effectively inhibit viral replication after a one-time administration, which is particularly useful in managing influenza infections.

In contrast, other options like multiple oral doses would imply a need for ongoing treatment, which is not how Xofluza is designed. Intravenous infusion would suggest a more complex administration route typically reserved for more severe conditions requiring hospitalization. Lastly, inhalation delivery systems are more aligned with medications for respiratory conditions but do not apply to this specific antiviral treatment. Therefore, the nature of Baloxavir marboxil as a single oral dose is a defining characteristic of its use in clinical practice.
