PROCESS FOR PRODUCING EDIBLE ORAL ADMINISTRATION PREPARATION OF AGGREGATED SUBSTANCE-CONTAINING LAMINATED FILM, AND EDIBLE ORAL ADMINISTRATION PREPARATION OF AGGREGATED SUBSTANCE-CONTAINING LAMINATED FILM

摘要

In the compression bonding of edible layers having rugged surfaces due to the presence of aggregated substance with these rugged surfaces arranged in opposed relationship, an edible layer substantially free of any aggregated substance is interposed therebetween. Thus, there can be produced an edible oral administration preparation of aggregated substance-containing laminated film having such a multilayer structure that extremely thin edible layers are piled one upon another. The multilayer structure resulting from the above compression bonding would enable satisfying the requirement of quantitative accuracy imposed on pharmaceutical oral administration preparations, etc. and due to the absence of time constraints on drying operation, would enable providing a production process excelling in productivity.
