Abstract (en)

[origin: WO2005123131A2] This invention provides compositions and methods providing, e.g., stable powder particles containing bioactive materials. The methods include, e.g., high pressure spraying of the bioactive materials in solution or suspension, with viscosity enhancing agents, organic solvents, and/or surfactants. Formulations are provided for spraying therapeutic bioactive materials into powder particles containing amino acids and sugars. Compositions of the invention provide, e.g., high initial purity, high stability in storage, and reconstitution at high concentrations.
