Abstract
The present invention relates to methods of making a powder for inhalation comprising a first step of mixing particles of a force-controlling agent selected from the group consisting of phospholipids, titanium dioxide, aluminum dioxide, silicon dioxide, starch, and salts of fatty acids, with particles of one or more pharmacologically active materials, wherein the mixing is achieved by one or more of the processes of sieving, mixing or blending, and wherein the mixing results in the particles of the force-controlling agent being disposed on the surface of the particles of the one or more pharmacologically active materials as either a particulate coating or as a continuous or discontinuous film.
