Abstract: An actuator housing (100) for use with a metered dose inhaler (MDI) device which comprises a housing portion (115) having a nozzle block (130) in which an actuator seat (135) and an actuator nozzle (145) are formed. The housing portion has an axis (120) which is angled with respect to a vertical plane which is perpendicular to a base portion or thumb grip (150) formed at a closed end thereof. A mouthpiece portion (125) is joined to the housing portion which has a roof section (180) and a floor section (125b). The roof section is angled upwards with respect to the floor portion, and provides a cross-piece (185) with which teeth of a patient can engage. Such an actuator housing addresses problems associated with buccal and tongue deposition of medicaments, as a spray of medicament from the actuator nozzle is directed over the tongue and into the airway.

Abstract: A pressurized metered dose dispenser (100) for dispensing an aerosol formulation comprising particles of a medicament suspended in liquefied propellant, optionally in combination with one or more excipients, the dispenser comprising an aerosol container (1) equipped with a metered dose valve (10), where a formulation chamber is defined in part by the internal walls of the container, and wherein the dispenser further comprises a porous, fluid permeable, particulate semi-permeable body (40) located within the formulation chamber adjacent to the metered dose valve.

Abstract: The present invention addresses the problem of turbophoresis and provides a relatively simple and low cost solution for a metered dose inhaler, in particular, a pressure-actuated metered dose inhaler. A metering valve (100) comprises a valve body (110), a valve stem (130) mounted within the valve body (110) and a spring element (140) for biasing the valve stem (130) in an “at rest” position. A pre-metering region (170) is formed in the valve stem (130) which is provided with a miniature valve seal (210) at its inlet (180). The miniature valve seal (210) effectively isolates the pre-metering region (170) from surrounding bulk formulation (4) within a canister (1) in which the metering valve (100) is mounted when the valve stem (130) is in the “at rest” position.
