Abstract: An aerosolization device comprises a chamber adapted to contain a powder pharmaceutical formulation, a lid at least partially covering the chamber, at least one piercing element forcible through the lid to provide access to the powder pharmaceutical formulation, and a shapeable surface extending from the chamber, the shapeable surface being adapted to undergo a shape change to form a conduit. The powder pharmaceutical formulation may be extracted from the chamber by a user inhaling through the conduit. In another version, the lid is removable from the chamber without the need for a piercing element.

Abstract: The present invention provides storage stable dry powder compositions of IL-4R. The powder compositions demonstrate superior chemical and physical stability over their solution counterparts, particularly upon storage under varying conditions of temperature and humidity. Moreover, the powders, as prepared, possess good aerosol properties, which are maintained upon storage.
