Abstract
An actuator for a pressurized metered dose inhaler providing a significant reduction in the non-respirable coarse fraction of the emitted aerosol medicament impacting in the oro-pharynx, with consequent less associated side effects and oral candidiasis in the patient, due to the fact that the mouthpiece portion has a central rounded opening of a well-defined width and distance from the nozzle aperture and also provided with a cylindrical recess, whose central axis is aligned with the central longitudinal axis of the mouthpiece portion and with the central longitudinal axis of the nozzle channel.
