The invention provides exemplary methods and apparatus for aerosolizing a pharmaceutical formulation contained within a receptacle. In one method, a metered amount of a pressurized gas is provided, with the pressurized gas previously being in equilibrium with a liquid. The metered gas is released to create a high pressure gas stream. The high pressure gas stream is flowed through an aerosolization mechanism to extract the pharmaceutical formulation from the receptacle and to disperse the pharmaceutical formulation within the gas stream to form an aerosol.
L'invention concerne des exemples de procédés et appareils permettant de disperser en aérosol une formulation pharmaceutique contenue dans un récipient. Selon un procédé, on utilise une dose donnée de gaz sous pression, ledit gaz sous pression se trouvant déjà en équilibre avec un liquide. La dose de gaz est libérée de manière à créer un flux gazeux haute pression. Ce flux gazeux haute pression passe dans un mécanisme de production d'aérosols, afin d'extraire la formulation pharmaceutique du récipient et de la disperser dans le flux gazeux pour former un aérosol.
