Abstract
A hand held aerosol actuator involving an aerosol source and a chamber having walls defining a constriction aperture. The aerosol source communicates with the chamber and directs an aerosol dose along an axis into the chamber. The constriction aperture is coaxial with the exit orifice and is dimensioned such that the respirable mass of the aerosol dose is increased relative to the respirable mass of an aerosol dose expelled through a like actuator not having the constriction aperture.
