- the AUC of the solid pharmaceutical composition of Example 5 was 121% compared to the AUC of the methylcellulose suspension. Therefore, it was shown that the solid pharmaceutical composition of the present invention exhibits good absorbability even in an in vivo test.
- the known compound A and L-proline, and crystalline cellulose and / or croscarmellose sodium are contained, and the known compound A and L-proline form a co-crystal.
- the solid pharmaceutical composition not shown showed good dissolution properties and dissolution stability. Since known compound A is considered to have a co-crystal structure with L-proline due to hydrogen bonding by an OH group, formation of hydrogen bond between known compound A and L-proline is inhibited, so that known compound A Guess that the free body will be maintained.
- Example 6 Tablets were prepared based on the formulation in Table 8 (the numbers in the table are the weight (mg) of each ingredient used).
- a known compound A, crystalline cellulose and croscarmellose sodium were mixed and then molded with a single tableting machine to prepare a tablet of the present invention.
- Example 6 Evaluation of dissolution property The tablet manufactured in Example 6 was subjected to the dissolution test of the composition immediately after the manufacture in the same manner as in Test Example 2. The test results are shown in FIG.
