Abstract
A drug delivery device capable of forming a medicated mist that reaches the nasal and paranasal sinus cavities contains a puncturing element within its canister. The puncturing element is used in combination with a compartment that contains a filling. The compartment is optionally detachable from an interior of the device or entirely separate from the device. The puncturing element punctures the compartment, releasing the filling into the reservoir of the device to provide a medicated liquid. The device may store any form of medication so long as the medication remains stable. When dry powder forms are desired, the reservoir and/or compartment may be filled with a solution or diluent so as to form the medicated liquid, which may then be dispensed as a mist through the device following the puncturing.
