The invention provides a novel method for obtaining solid micro -or nanoparticles with a homogenous structure. A method is provided for obtaining solid micro -or nanoparticles with a homogenous structure having a particle size of less than 10 µm where the processed solid compound has the natural, crystalline, amorphous, polymorphic and other features associated with the starting compound. In accordance with the invention a method which also makes it possible to obtain solid micro -or nanoparticles with a substantially spheroidal morphology is provided.
