摘要：
Actuators for an aerosol inhalation device containing a housing adapted to receive an aerosol canister containing a pressurized medicament formulation, a mouthpiece portion through which the user inhales, a nozzle block and an orifice and a tubular element extending in the mouthpiece portion from the orifice aperture in a longitudinal axis substantially aligned with a longitudinal axis of the mouthpiece portion provide a significant reduction in the non-respirable, coarse fraction of the emitted aerosol medicament via inertial impaction and retention in the actuator than in the oro-pharynx, with consequent less associated side effects and oral candidiasis in the patient. In addition the presence of the tubular element has minimal, negligible impact on the fine particle dose and on the particle size distribution (PSD) of the delivered particles having aerodynamic diameter lower than 9 mum.Un actuador de un dispositivo de inhalación de aerosol, que comprende un alojamiento para recibir un recipiente de aerosol, una porción de conducto que termina en una abertura a través de la cual inhala el usuario, una cavidad que recibe un vástago de válvula, y un elemento tubular que se extiende en la porción de conducto； un inhalador.
