Abstract
Protein microspheres are produced by contacting an aqueous solution of a macromolecule and a polymer with a surface at a high surface area to volume ratio, and heating the solution. The microspheres are useful for preparing pharmaceuticals of defined dimensions which can be delivered to a patient by inhalation therapy.
