Pharmaceutical compositions containing cyclosporin microparticles are prepared by applying energy to cyclosporin particles in the presence of phospholipid and one or more surface modifiers. These microparticles consist essentially of cyclosporin, a phospholipid and at least one surfa
Hydrothermal BaTiO.sub.3 crystallites were coated with Bismuth solutions prepared from Bismuth metal-organics and anhydrous solvents. The Bismuth metal-organics were Bi 2-ethylhexanoate and Bi-neodecanoate. Bismuth oxide was also used as a comparison to the Bismuth solutions. BaTiO.sub.3
Submicron size particles of pharmaceutical or other water-insoluble or poorly water-insoluble substances are prepared using a combination of one or more surface modifiers/surfactants such as polaxomers, poloxamines, polyoxyethylene sorbitan fatty acid esters and the like together with
