Granular preparations for oral administration wherein an anion exchange resin is contained as the active ingredient and cores of 3 to 4 mm in diameter are coated with a water-soluble polymeric cellulose as an inner coating layer and an aqueous dispersion of ethyl cellulose as an outer coating layer. Owing to this constitution, these preparations show no sliminess characteristic to cellulose, are free from adhesion of grains in the mouth and have a favorable texture at administration without any unacceptable feel as in large tablets.

La présente invention concerne des préparations de granulés pour administration orale, dans lesquelles une résine à échange anionique est le principe actif et des noyaux de 3 mm à 4 mm de diamètre sont revêtus d'une cellulose polymère soluble dans l'eau sous forme de couche interne, et d'une dispersion aqueuse de cellulose éthyle sous forme de couche externe. Du fait de leur composition, ces préparations ne présentent pas de caractéristiques de surbroyage de la cellulose, les grains n'adhèrent pas dans la bouche et elles possèdent une texture qui favorise leur administration, sans laisser un goût inacceptable comme c'est le cas pour les gros comprimés.
