Solid preparation |
| abstract |
The present invention relates to a solid preparation having an easily controllable elution property of a drug, and a method for improving dissolution of a drug. n A solid preparation 1 comprises a drug-containing unit 2 containing a drug, a gel-forming layer 4 for covering the drug-containing unit 2 and forming a gel by water absorption, and an intermediate layer 3 interposed between the drug-containing unit 2 and the gel-forming layer 4. The elution property of the drug is improved by forming a plurality of pores extending from a surface of the gel-forming layer toward the intermediate layer in the gel-forming layer 4 . The gel-forming layer 4 may be covered with an anti-adhesive layer 5 . The anti-adhesive layer 5 may have a pore 6 extending from a surface thereof and communicating with the pore of the gel-forming layer. The drug-containing unit 2 may contain a cationic or basic drug. The gel-forming layer 4 may contain an anionic or acidic polymer. |
