a housing body;
a propellant canister in the housing body capable of containing a propellant which is different from the compound, the propellant canister displaceable between an unactuated position and an actuated position;
a puncture element in the housing body positioned to puncture the propellant canister and cause release of the propellant from the propellant canister when the propellant canister is displaced to the actuated position;
a diffuser in the housing body, acting as a one-way check-valve to diffuse the propellant upon its release from the propellant canister;
a dose holding chamber in the housing body, separated from the propellant canister, capable of containing a unit dose of the compound, the dose holding chamber positioned such that the released propellant flows into the dose holding chamber from the diffuser and causes the compound to be propelled from the dose holding chamber;
a nozzle positioned such that the compound flows through the nozzle upon being propelled from the dose holding chamber for delivery to the nasal cavity; and
an actuation element comprising an actuation lever, wherein actuation of the actuation lever is configured to displace the propellant canister from the unactuated position to the actuated position.
