Abstract: A dispersible powder composition comprises aminoglycoside for delivery to the lungs. The composition is effective to provide a therapeutically effective therapy via administration of less than 6 respirable unit doses by inhalation, wherein each unit dose comprises a volume of 0.30 to 0.95 mL.

Abstract: Stabilized dispersions are provided for the delivery of a bioactive agent. The dispersions preferably comprise a plurality of perforated microstructures dispersed in a suspension medium that typically comprises a liquid fluorochemical. As density variations between the suspended particles and suspension medium are minimized and attractive forces between microstructures are attenuated, the disclosed dispersions are particularly resistant to degradation, such as by settling or flocculation. In particularly preferred embodiments the stabilized dispersions may be directly administered to the lung of a patient using an endotracheal tube or bronchoscope.

Abstract: A pulmonary delivery medicament comprises a plurality of particulates, the particulates comprising a structural matrix and a water insoluble and/or crystalline active agent. The particulates have a geometric diameter of 0.5 to 50 ?m. The water insoluble active agent can be a fungicide, antibiotic, budesonide. A method of making the medicament comprises forming a liquid feedstock, and forming a feedstock suspension by suspending in the liquid feedstock, the active agent and an excipient capable of forming a structural matrix, such as a phospholipid. The feedstock suspension is spray dried to produce the particulates.

Abstract: Formulations are provided for pulmonary administration of an antifungal agent to a patient. Methods of using the formulations in the treatment of antifungal infections are also provided, including treatment of pulmonary aspergillosis with amphotericin B-containing formulations. Methods of manufacturing the formulations to achieve optimum properties are provided as well.

Abstract: A pulmonary delivery medicament comprises a plurality of particulates, each particulate having a perforated microstructure comprising a phospholipid structural matrix and active agent, the phospholipid structural matrix comprising greater than about 50% w/w phospholipid, and the particulates having a geometric diameter of from 0.5 to 50 ?m. The medicament can be made from a liquid feedstock having greater than about 20% w/w phospholipid with an added active agent, which is spray dried to produce the particulates.

Abstract: A composition includes particles including at least about 95 wt % of amphotericin B, wherein the particles have a mass median diameter ranging from about 1.1 ?m to about 1.9 ?m. Another composition also includes particles including at least about 95 wt % of amphotericin B, wherein at least about 80 wt % of the particles have a geometric diameter ranging from about 1.1 ?m to about 1.9 ?m. Yet another composition includes particles including amphotericin B, wherein the particles have a mass median diameter less than about 1.9 ?m, and wherein the amphotericin B has a crystallinity level of at least about 20%. Unit dosage forms, delivery systems, and methods may involve similar compositions.

Abstract: A pharmaceutical formulation for pulmonary administration is disclosed. The pharmaceutical formulation comprises a lipid component and an active agent, wherein the pharmaceutical formulation has a liquid phase transition temperature of less than or equal to 37° C. when hydrated and a liquid phase transition temperature of greater than 57° C. when non-hydrated, whereby the lipid component spontaneously encapsulates and/or entraps the active agent when the pharmaceutical formulation is administered to the lungs. A targeting agent may also be provided. In one version, the pharmaceutical formulation is useful to treat an infection, such as an inhalation anthrax infection.

Abstract: Stabilized dispersions are provided for the delivery of a bioactive agent to the respiratory tract of a patient. The dispersions preferably comprise a stabilized colloidal system which may comprise a fluorochemical component. In particularly preferred embodiments, the stabilized dispersions comprise perforated microstructures dispersed in a fluorochemical suspension medium. As density variations between the suspended particles and suspension medium are minimized and attractive forces between microstructures are attenuated, the disclosed dispersions are particularly resistant to degradation, such as by settling or flocculation. In particularly preferred embodiments, the stabilized dispersions may be administered to the lung of a patient using a nebulizer.
