Is relenza used as an inhaled powder?

What form does Relenza come in?

Relenza, also known as zanamivir, is an antiviral medication used to treat and prevent influenza A and B [1]. It's primarily administered through inhalation, specifically as an inhaled powder.

How is Relenza inhalation administered?

For treatment, the inhaled powder is delivered using a specially designed Diskhaler device, which helps to ensure the patient inhales the correct amount of medication [2]. This device consists of a powder container connected to a mouthpiece.

Is there an alternative inhalation device for Relenza?

While the Diskhaler was the initial device, Relenza can also be administered through a new device called the Ellipta inhaler, which is simpler and easier to use [3]. This development was part of Novartis's efforts to improve patient convenience and compliance.

Does Relenza have oral versions?

No, Relenza is not available in oral tablet or liquid forms. Its unique mechanism requires direct inhalation of the inhaled powder to be effective against influenza viruses.
