- the uniformity of ibudilast content in the tablets prepared in Examples 1 and 2 and Comparative Example 1 was evaluated according to the 14th revised Japanese Pharmacopoeia content uniformity test.
- the content of ibudilast in each tablet was measured by the HPLC method.
- Table 4 shows the judgment values for each tablet.
- the judgment value is the judgment standard of the 14th revised Japanese Pharmacopoeia content uniformity test (No more than 15.0%) and the content of ibudilast in the tablets was uniform.
- the tablets prepared in Comparative Example 1 that were simply mixed without going through the granulation process were Although the content of the Hyde Mouth Gel Forming Substance was small (16.7% by mass) compared to Examples 1 and 2, the judgment value exceeded the above judgment standard, and the ibudilast in the tablet The content was uneven.
- Figure 1 shows the release rate over 90 hours (2160 minutes). From this figure, it can be seen that the initial drug release is greater in the tablet of Comparative Example 1 than in Examples 1 and 2.
