Abstract: A powdered, dispersible composition having stable dispersibility over time is provided. The composition exhibits a characteristic glass transition temperature (Tg) and a recommended storage temperature (Ts), wherein the difference between Tg and Ts is at least about 10° C. (i.e. Tg−Ts is greater than 10° C.). The composition comprises a mixture of a pharmaceutically-acceptable glassy matrix and at least one pharmacologically active material within the glassy matrix. It may be further mixed with a powdered, pharmaceutically-acceptable carrier.

Abstract: According to the subject invention, dispersible dry powder pharmaceutical-based compositions are provided, including methods for their manufacture and dry powder dispersion devices. A dispersible dry powder pharmaceutical-based composition is one having a moisture content of less than about 10% by weight (% w) water, usually below about 5% w and preferably less than about 3% w; a particle size of about 1.0-5.0 &mgr;m mass median diameter (MMD), usually 1.0-4.0 &mgr;m MMD, and preferably 1.0-3.0 &mgr;m MMD; a delivered dose of about >30%, usually >40%, preferably >50%, and most preferred >60%; and an aerosol particle size distribution of about 1.0-5.0 &mgr;m mass median aerodynamic diameter (MMAD), usually 1.5-4.5 &mgr;m MMAD, and preferably 1.5-4.0 &mgr;m MMAD. Such compositions are of pharmaceutical grade purity.

Abstract: Dispersibility of a respirable powder, administrable by inhalation, is increased by including a pharmaceutically acceptable water-soluble polypeptide.

Abstract: According to the present invention, methods and compositions are provided for spray-dried, interferon-based dry powder compositions, particularly interferon-beta. The compositions are useful for treating conditions in humans that are responsive to treatment with interferons. In particular, the methods of the present invention rely on spray drying to produce stable, high-potency dry powder formulations of interferons, including but not limited to IFN-beta. Surprisingly, it has been found that IFN can be prepared in high potency, dry powder formulations by spray drying. Such dry powder formulations find particular utility in the pulmonary delivery of IFN.
