| titleOfInvention | Controlled release drug delivery system for oral administration |
| abstract | The present invention relates to a controlled release drug delivery system for oral administration and a controlled release porous film-forming composition used in the system, comprising a core containing a pharmacologically active ingredient; and an outer surface of the core A controlled release porous membrane that is coated and includes one or more film forming materials selected from the group consisting of cellulose compounds, polymethacrylates, acetate compounds, polyamides, polyurethanes, and sulfonated polystyrenes; By using the controlled release drug delivery system for oral administration of the present invention, the drug release rate can be adjusted, so that the drug can be released efficiently and continuously in the gastrointestinal tract. The release time of the drug can be adjusted by the thickness, composition of the membrane constituent material, the amount of plasticizer, and the amount of excipients. The controlled release formulation can be manufactured by coating with a porous membrane, which not only simplifies manufacturing and reduces the cost of the product, but also has excellent membrane stability for long-term storage, temperature and humidity A controlled-release preparation for oral administration that is not affected can be produced, and mass production is possible. |
