Abstract:
Objective: In order to solve the problem of moisture absorption for Biantong Capsule, the extract granule of Chinese medicine is covered with HPMC for Biantong Capsule. Methods: Taking moisture absorption rate as measure index, various facters effected the moisture absorption rate, and the optimal coating process can be selected with well disturbed uniform design and computer analog test. Results: Under the condition of 25℃, relative moisture 75% and 100% respectively, the moisture absorption rate is lower than uncovered granules, the critic relative moisture of covered granules is greater than that of uncovered granules. Conclusion: Chinese medicine of Biantong Capsule covered with HPCM can be served as a good anti moisture method.
