Definitions
- the present invention relates to an oral preparation having improved release of a basic physiologically active substance (basic drug).
- Such a formulation examples include, for example, a compound containing an enteric polymer which is soluble in the stomach in an acidic environment and is soluble in the small intestine, which is neutral to basic, as a drug release controlling agent.
- the enteric polymer has an acidic group such as a carboxy group in the molecule, it does not dissolve in an acidic environment but dissolves in a basic environment.
- formulations containing enteric polymers release the drug little by little without disintegration in the stomach, but release the drug in the small intestine in a neutral to basic environment.
- by coating the surface with an enteric polymer it is possible to further suppress drug release in the stomach.
- enteric polymers may also exhibit sustained drug release in the small intestine.
- enteric high molecules are more likely to disintegrate or dissolve as the alkalinity becomes stronger, and the liquidity of the small intestine is higher in the lower part (pH 6 in the upper part, pH 7.6 in the middle to lower part).
- Formulations with enteric polymers release more drug in the lower part of the small intestine than in the small intestine, which has high drug absorption. As a result, there is also an effect that the blood concentration of the physiologically active substance can be further stabilized.
- Japanese Patent Publication No. 7-712129 discloses that a mixture of a physiologically active substance and crystalline cellulose is mixed with an enteric polymer such as a methacrylic acid copolymer and granulated. What is manufactured is disclosed. However, as will be described in Examples (Reference Example 1) described below, it is clear from the present inventors that when the physiologically active substance shows basicity, the enteric polymer significantly interferes with the release of the basic drug. Was. That is, in a preparation containing a basic physiologically active substance, when an enteric polymer is added, it may not be possible to secure a sufficient drug blood concentration. Disclosure of the invention

- this publication does not specifically disclose a preparation having such a component constitution.
- the force probably due to lack of experimental confirmation, states in this publication that the electrolyte (in this publication "alkyl metal halide or alkyl earth metal") controls the rate of active substance release. Therefore, it is recognized only as a substance for suppressing the release of a physiologically active substance, and as a substance for improving the release of a physiologically active substance in the intestine as in the present invention.
