Abstract
The invention relates to a fluidized-bed method for simultaneously obtaining the dry matter from aqueous solutions of extract substances from deproteinized calves blood and producing granules which can be compressed to give solid medicament forms and contain at least 50% by weight of extract substances, relative to the total dry weight of the granules, a binder and pharmaceutically acceptable fillers and carriers, by spraying an aqueous solution of the extract substances and of the binder on to the fillers and carriers and granulating the mixed material at a defined water content in the fluidized bed. After drying, granules ready for compression are obtained, and they are used for producing solid medicament forms of high stability and constant quality.
