ABSTRACT
Objective To optimize the forming process of Wuzibushen Capsules. Methods Category and ratio of accessories were investigated by taking moisture absorption percentage as index. The inspected angle of repose, bulk density and critical relative humidity were also investigated. Results Starch was used as the excipien. Remedium cardinale and starch in the ratio of 1.15∶1.25 was more appropriate, 60% alcohol was added, dried at 60 ℃. Granules had a good fluidity, critical relative humidity was about 62%. Conclusion The forming technology was reasonable and provide reliable basis for production.
ABSTRACT
OBJECTIVE: To study optimal formulation process of Rutongning granule. METHODS: The ratio of main components to excipients was optimized with hygroscopicity,granulation and dissolubility index. RESULTS: The optimal ratio of extract powder to saccharose was 1 ∶ 1.5. The made granules were characterized with low hygroscopicity, high granulation,high dissolubility and low cost. And its critical relative humidity was 65%. CONCLUSION: The study provides theory evidence for formulation process of Rutongning granule and the control of production environment.
ABSTRACT
[Objective]To ascertain the best formulation process of Tangkening Granule. [Method]By determinating hygroscopicity, granulation and dissolubility, the appropriate recipient and its formula are selected. [Results]The best excipient is 1∶0.5. The made granules have low hygroscopicity and high granulation and high dissolubility. And its critical relative humidity is 70%. [Conclusion]The experimental results provide the basis of the ascertainment of formulation process and the control of product inviroment of Tangkening Granule.
ABSTRACT
Objective: To improve the physical properties of micromeritics of the extracts of Fengshilin capsule, such as anti moisture. Methods: Critical relative humidity, absoption curve of moisture, angle of repose were used as the norms of the research. The suitable excipients and formulation process of Fengshilin capsule have been sieved. Results: It was feasible that the combined excipients of microcystalline cellulose and starch (in a ratio of 1∶1) were mixed with the extract powder. The absorption of moiture of the extract powder was improved. The humidity of mass production and store was lower than 45%. Conclusion: The research has been found to be an effective in the process of Fengshilin capsule.
ABSTRACT
AIM:To prepare the Lyophiled Royal Jelly Soft Capsule and study its stability and Influential factors.METHODS:The suspending agent and processing method were optimized using sedimentation volume rate as the index.Soft capsules were prepared and product stability under high temperature and high humidity environment was studied according to the determination of the content of 10-HAD by HPLC.RESULTS:The finished product yield in pilot test was more than 90%,the soft capsule products stored in cold were stable,while those stored under room temperature or high temperature and high humidity were unstable with a noticeable decrease in quality.Water content in capsule shell affects the 10-HDA content of the finished product.CONCLUSION:The preparative process is feasible and the products should be storaged in cold enviroment.
ABSTRACT
AIM: To selecte the best process for Kangfuxin Drop Pills. METHODS: With appearance,weight coefficient of variation and dissolution time for index sign,orthogonal design was applied. RESULTS: The results indicated that the excellent factors and levels were as follows: the scale between PEG6000 and drug extraction was four to one,the temperature of drug fluid was at 85 ?C,drip rate was 40 drops/min. CONCLUSION: The method adopted is steady and feasible.
