Abstract
The object of the invention is a process for the preparation of microgranules to be used in controlled-release liquid pharmaceutical compositions. Operating with high-shear mixer-granulators within clearly established crucial parameter ranges, this process results in microgranules having a particle size distribution, a density, a surface and a shape which make them particularly suitable for coating and then suspension in fluids.
