A process for preparing coated microparticles, which process comprises preparing a solvent solution of an active ingredient to be encapsulated and a film-forming polymer, removing the solvent to provide a dry, composite, uniform admixture of the active ingredient and the polymer material, reducing the composite admixture to a defined smaller particle size distribution, coating the reduced composite core particles in a fluidized bed, with a uniform defined wall thickness of the same or substantially the same film-forming polymer material to provide composite core coated microparticles.
