Document Type and Number:
WIPO Patent Application WO2010110321
Kind Code:
A1
Abstract:
A gel-forming layer (4) covering a drug-containing part (2) is covered with an adhesion preventing layer (5) by applying an adhesion preventing composition, which contains a water-soluble cellulose ether (such as HPMC) and an anionic polymer (such as a carboxyvinyl polymer), to the gel-forming layer (4), so that a preparation (1) is prevented from adhering to the inner wall of the oral cavity. The gel-forming layer (4) can be formed from a gel-forming agent (a carboxyvinyl polymer), a crosslinking agent, and a base agent (a polyvinyl alcohol or the like). In addition, an adhesive layer (3) may be interposed between the drug-containing part (2) and the gel-forming layer (4).
