[0048] Determination of the Dissolution Profile of the Invention
[0049] The samples of the above-mentioned examples were taken, and the dissolution curve was determined by the second method of the Dissolution and Release Determination Method 0931 of the Fourth General Principles of the Chinese Pharmacopoeia 2020 Edition. The dissolution method is: paddle method, 0.1N HCl solution and pH4.5 phosphate buffer, 900ml, 75rpm, 37±0.5°C, sampling time 10, 15, 30 and 60min. The dissolution profile is attached Figures 5 to 6 . It can be seen that in the two dissolution media, the dissolution of Example 1 and Example 3 prepared by micronized raw materials are significantly faster than those of Example 2 and Example 4.
