Abstract
A delivery device for the delivery of an agent to the mouth, nose or other bodily site of a user. The delivery device includes an aerosol canister that is actuated to expel propellant, which captures and disperses the agent. In a preferred embodiment, the propellant captures and disperses the agent into the mouth or nose of a user, and inhalation by the user directs the agent to the lungs of the user. The delivery device is particularly suitable for the treatment of bronchial asthma, respiratory conditions and for the delivery of systemically absorbed agents.
