| titleOfInvention | Composition for producing controllable porous membrane of oral drug delivery system and oral drug delivery system using controllable porous membrane |
| abstract | The present invention relates to a sustained release porous membrane-forming composition for oral drug delivery devices and oral sustained release drug delivery device prepared using the same, wherein the composition is a cellulose-based compound, polymethacrylate, semipermeable polyamide, semipermeable poly At least one film forming material selected from the group consisting of urethane and semipermeable sulfonated polystyrene.n n n As described above, the sustained release drug delivery device made of the sustained release porous membrane-forming composition of the present invention can control the release rate of the drug to efficiently and continuously release the drug in the gastrointestinal tract. In addition, depending on the thickness of the porous membrane, the composition of the membrane constituents, the amount of plasticizer, the amount of excipients, the release time of the drug can be controlled, and a small amount of the porous membrane is coated on existing tablets or granules to provide a basic sustained release formulation. It is easy to manufacture and reduce the cost of the product, and excellent membrane stability allows the manufacture of oral sustained release preparations that are not affected by long-term storage or temperature and humidity, and mass production is possible. |
