Abstract
A nasal drug delivery device for delivering a plume derived from a propellant and a drug compound. The drug compound is in an intranasal dosage form in the form of powder, suspension, dispersion, or liquid. The propelled intranasal dosage form is deposited within the upper nasal cavity such as the olfactory region. The drug deposited within the olfactory region is delivered to the brain avoiding the blood-brain-barrier. Hydrofluoroalkane propellant from a pressurized canister is channeled to a diffuser and drug-containing channel where the intranasal dosage form is aerosolized. The aerosolized intranasal dosage form passes through a nozzle thus delivering a plume to the user's upper nasal cavity.
