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.

Abstract: A stable crystalline micronized particulate of a glycopyrronium salt may be prepared by suspending the drug in a water-immiscible anti-solvent in which the drug has little or no solubility and micronizing the suspension. The resulting drug particles are physically stable with regard to agglomeration and/or aggregation on storage.

Abstract: Actuators for a pressurised metered dose inhalers containing (a) a housing adapted to receive an aerosol canister containing a pressurised medicament formulation, (b) a nozzle block defining the receptacle for the aerosol canister valve stem, the expansion chamber or sump, the nozzle channel its external aperture, and (c) a mouthpiece portion comprising a central rounded opening of a defined width and distance from the nozzle aperture and 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, provide a significant reduction in the non-respirable coarse fraction of the emitted aerosol medicament via inertial impaction and retention in the actuator rather than in the oro-pharynx, with consequent less associated side effects and oral candidiasis in the patient.
