[0003] Among these, calcium carboxymethylcellulose has been widely used in disintegrants used in conventional tablets. This is because calcium carboxymethylcellulose is tasteless, odorless, and white, and has good disintegration, swelling ratio, compression moldability, and the like.

[0004] Solid tablets disintegrate in the digestive juices of the stomach and intestines after oral ingestion, release medicinal ingredients, and allow the human body to absorb the medicinal ingredients from the walls of the stomach and intestine. It is necessary to sufficiently disintegrate in the digestive juice while keeping it stable.

However, the two functions are in a backlash relationship, and it is difficult to find a disintegrant compatible with both functions, and there has been a problem that either function cannot be sufficiently achieved. The same applies to the above-mentioned calcium carboxymethylcellulose, and the disintegration is good, but the shape stability is difficult.

The CMC-Na used in the present invention has a highly degradable etherification degree of 0.2 to 0.5 and an oxidation degree of 0.01 to 0.5.
By mixing the CMC-Na of 0.2 and the CMC-Na having a strong cohesive degree of etherification of 0.8 to 2.0 in an optimum ratio, both functions which have not existed before can be obtained.

[0010] CMC-Na is dissolved in water and used as a binder. However, when the degree of etherification is reduced (0.5 or less), it tends to be insoluble. Further, by specifying the degree of oxidation, a certain range of carboxymethylcellulose acid is obtained, and insolubilization is further promoted.

CMC-Na having a low degree of etherification exhibits a function as a disintegrant. The degree of etherification is 0.2 ~
It is necessary to be 0.5, but preferably 0.2 to 0.4. This is because the lower the degree of etherification and the higher the degree of oxidation, the lower the water solubility, and the faster the disintegration of the tablet in the stomach and intestines.

CMC-Na with a high degree of etherification exhibits a function as a binder. In addition, there is an effect of improving the yield by suppressing the occurrence of chips and the like at the time of molding for tablets and stabilizing the shape at the time of handling. The degree of etherification is 0.8-2.
It is necessary to be 0, but it is preferably 1.0 to 1.5. The higher the degree of etherification, the better, but
If it is 2.0 or more, the cost increases with an increase in the amount of the drug during the production of CMC-Na, which is not preferable.

(A) :( b) = It is necessary to mix at a weight ratio of 10:90 to 50:50, but 20:80 to 40:60.
It is preferred that When the degree of low etherification CMC-Na is less than 10%, the disintegration of the tablet is reduced, and when it is more than 50%, disintegration in the stomach and intestine is delayed, resulting in a delay in absorption of the medicinal component and a decrease in yield.

The particle size of the powder may be fine, but is preferably 27 μm or more in consideration of the production cost.
