An inhalation activated device or dispenser is disclosed. In particular, the dispenser comprises a housing for containing an aerosol canister containing a medication wherein the canister is moveably contained in the housing upon inhalation by the patient whereby a metered dose of a spray is initiated and a controlled period of time is established by a dwell means.

DETAILED DESCRIPTION The present invention comprises a metered dose dispenser for aerosol medication contained in a housing having a mouthpiece for insertion into a patient's mouth.
A mechanical actuator mechanism is provided in cooperation with the canister, in its initial locked position, which upon inhalation by a patient causes the canister to dispense a metered dose of medication as a spray from the mouthpiece to the patient.
The dose is established by a metering valve associated with the canister.
A dwell means is provided which ensures complete discharge of the metered dose and subsequently, complete filling of the metering valve with the next dose after the dispensing.
