Nasal drug delivery device
First Claim
1. A device for delivery of a compound to an olfactory region of a nasal cavity, the device comprising:
- an actuator body comprising a vertical portion and an angled portion, the vertical portion comprising a contoured surface to accommodate a facial component of a user'"'"'s face and configured to house a pressurized propellant container containing propellant and a first portion of a connection channel, the first portion of the connection channel configured to be in communication with the propellant container, the angled portion comprising an additional contoured surface to accommodate an additional component of the user'"'"'s face and configured to house a second portion of the connection channel;
a diffuser in communication with the second portion of the connection channel;
a drug chamber in communication with the diffuser, the drug chamber configured to hold the compound;
a nozzle in communication with the drug chamber, wherein propellant released from the propellant container is configured to travel through the connection channel, contact the diffuser, and propel the compound out the nozzle forming a plume.

Abstract
A compound delivery device for delivering a plume derived from a propellant and a drug formulation. The drug formulation is in an intranasal dosage form in the form of powder, suspension, dispersion or liquid. The propelled intranasal dosage form is deposited within the olfactory region of the nasal cavity. 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 chamber where the intra-nasal dosage form is aerosolized. The aerosolized intra-nasal dosage form passes through a nozzle thus delivering a plume to the olfactory region of a user'"'"'s nasal cavity.
