A method of preparing a pharmaceutical composition is described, comprising (1) atomizing a liquid formulation of a therapeutic agent to produce an atomized formulation; (2) freezing said atomized formulation to form solid particles; and (3) drying said solid particles at about atmospheric pressure to produce a powder, wherein said drying is performed in the presence of vibration, internals, mechanical stirring, or a combination thereof. Another method is described, comprising (1) atomizing a liquid formulation of a therapeutic agent to produce an atomized formulation; (2) freezing said atomized formulation to form solid particles; and (3) drying said solid particles to produce a powder; wherein the atomized formulation comprises droplets having an average mean diameter of between about 35 and about 300m, and/or the powder comprises dried particles having an average mean diameter of between about 35m and about 300m. Compositions made by the above methods, and methods of using the compositions, are also described.

Procédé de préparation d'une composition pharmaceutique, qui consiste (1) à atomiser une solution liquide d'un agent thérapeutique pour produire une solution atomisée, (2) à congeler ladite solution atomisée pour former des particules solides, et (3) à sécher lesdites particules solides à la pression atmosphérique environ pour produire une poudre, le séchage étant effectué en présence de vibrations, de turbulences internes, d'agitation mécanique ou d'une combinaison de ces procédés. La présente invention concerne un autre procédé qui consiste (1) à atomiser une solution liquide d'un agent thérapeutique pour produire une solution atomisée, (2) à congeler la solution atomisée pour former des particules solides, et (3) à sécher ces particules solides pour produire une poudre. La solution atomisée contient des gouttelettes dont le diamètre moyen est situé entre environ 35 µ et environ 300µ, et / ou la poudre contient des particules séchées ayant un diamètre moyen situé entre environ 35µ et environ 300µ. Des compositions préparées selon le procédé ci-dessus et des procédés d'utilisation desdites compositions sont également décrits.
