Problems solved by technology
[0003] Since controlled-release tablets need to use laser to open holes on the drug surface film during the production process, compared with ordinary tablets, controlled-release tablets are more difficult to produce during the production process. Therefore, in order to facilitate the production of caffeic acid osmotic pump controlled-release tablets , a new type of device is needed to solve this problem

Description
Technical field [0001] The present invention relates to a pharmaceutical preparation apparatus, specifically a preparation apparatus for penetration pump controlled release tablets, which belongs to the technical field of drug preparation. Background technique [0002] Coffee acid is an organic compound that is attributed to hydroxycinamic acid, and has two functional groups of phenolic hydroxyl groups and acrylic acid. The penetration pump controlled release tablets are composed of drugs, semi-permeable film materials, osmotic active materials and push agents. Separation pressure as a controlled release tablet in the release energy. The basic structure is to press the drug to press the drug to be pressed into the core, an outage of a layer of semiperceptible substance film, and then use a laser to make a small hole on the membrane. After oral administration, the gastrointestinal water passes through the semipermeable membrane to dissolve the drug, and the drug is dissolved after...
