The present addition relates to a pharmaceutical dosage form comprising a matrix and an active ingredient and which is characterised in that: A) the physiologically acceptable matrix is a solid and porous material which has been obtained in the dry state by cryodesiccation and compression to impart sufficient mechanical strength to the aforementioned material to prevent it, in the main, from cracking when a gaseous fluid is passed through its thickness; and B) the active ingredient combined with the abovementioned matrix consists essentially of microparticles having an average particle size of between 5 mu m and 0.01 mu m, and is chosen from substances which are 1 water-soluble or 2 coated. It also relates to the process for preparing this pharmaceutical dosage form.
