Abstract: The present invention relates to a device (20) for delivering a drug (30) to a user via a nasal or pulmonary route. The device can be a pressurised metered dose inhaler (200), an active dry powder inhaler (300/ 400) a soft mist inhaler (500) or a nebuliser (600). The device (20) comprises a propellant energy source (40) to deliver a drug (30), which propellant energy source (40) is or comprises an aerial gas (41) that is stored in a canister (45) separate of the drug, at a pressure of at least 2 Bar, adsorbed on an adsorbant (42) where it is released therefrom to dispense the drug (30). The device comprises a gas delivery mechanism (50) wth a metering chamber (52) which has a larger capacity than a traditional pressuised metered dose inhaler which is filler with an HFC propellant. The aerial gas (41) is released from the chamber on actuation and travels along a conduit (25) to displace a dose of a drug (30) from a dosing chamber (80) which is aerosolised and leaves the device via a second conduit (27) and exit (28) as a plume (60).
