The present invention relates to solid microparticulate oral pharmaceutical forms whose composition and structure make it possible to avoid misuse of the pharmaceutical active principle they contain. The invention relates to a solid oral pharmaceutical form which is characterized in that it contains anti-misuse means, in that at least part of the active principle it comprises is contained in coated microparticles for modified release of the active principle, and in that the coated microparticles have a coating layer which assures modified release of the active principle and simultaneously imparts crushing resistance to the coated microparticles so as to avoid misuse.
