Zusammenfassung: | A sustained-release multiple unit formulation containing a galantamine hydrobromide is provided to release the galantamine hydrobromide by coating release control drug layer with control film of release. A sustained-release multiple unit formulation containing a galantamine hydrobromide comprises: a pharmaceutical inactive multiple unit core; a release control drug layer of water-insoluble polymer; and a release control film. The multiple unit core comprises a white sugar sphere or white sugar containing white sugar and corn starch. The release control drug layer comprises the galantamine hydrobromide and is applied on the surface of the core. The water-insoluble polymer is ethylcellulose or aqueous dispersion of ethylcellulose. The release control film is applied on the surface of the layer and comprises water-insoluble polymer or water-soluble polymer. |
