| Abstract: | From the minigranules of the theophylline-based that prepared by extrusion-spheronization, the authors have envisaged the study of one of the parameters of operation (spheronizer speed) on the physical properties and lyoavailability of the active ingredient. It emerges that there is a clear influence of that parameters on the particle size distribution, the hardness, the friability, the density and the lyoavailability. |
