- the formulation evaluation the formability of the capsule at the time of dropping onto 10 ° C. MCT was examined as moldability, and was divided into four stages: excellent, good, acceptable, and impossible.
- Table 2 shows the results of examining the pharmaceutical properties and enteric properties. As shown in Table 2, the formulations 1 to 5 were all good in terms of formulation. As for enteric properties, in Examples 1 to 5, disintegration tests using the first liquid showed no disintegration in all 18 seamless soft capsules after 120 minutes. In the test using, disintegration was observed after 5 minutes, and all 18 seamless soft capsules were disintegrated after 30 minutes.
