Alzair™ is a nasal powder that is sprayed into the nose via a novel delivery method. Alzair™ particles absorb moisture from the nasal mucosa and swell to create a protective gel-like barrier in the nasal tract. This gel barrier stops allergens from making contact with the mucosa, stopping cell degranulation and the release of histamines from within the body.

The following image demonstrates the mechanism of action of Alzair™ e.g. the formation of a mechanical barrier.
