RESUMO
Lozenge is one of the traditional dosage forms of Chinese medicine. It has been recorded in traditional Chinese medical classics of all dynasties since the Eastern Han Dynasty and has been developing and evolving continuously. The unique pharmaceutical methods and application scope are the driving force of its emergence, existence, and development. Up to now, lozenge has been included in the Chinese Pharmacopoeia as an independent dosage form. Lozenge has been endowed with new meaning by modern Chinese medicine pharmaceutics, which is worth tracing origin and exploring value. The present study reviewed the origin and development of lozenge, compared lozenge with other similar dosage forms, analyzed the characteristics of modern and ancient dosage forms of lozenge, and discussed the development prospect and potential of lozenge in combination with the demand development of modern Chinese medicine preparation, so as to provide references for expanding the modern application of lozenge.

Temporary prescription preparation is the preparation processed into different dosage forms by relevant pharmacist according to the temporary preparation requirement and the personalized prescription made by the doctor in accordance with the syndrome differentiation and drug performance.It is an important part in personalized pharmaceutical services.Rational design of process route,production equipment and quality control method for the temporary prescription preparation,and establishment of technology research strategy and mode in accordance with the characteristics of traditional Chinese medicine temporary prescription preparations play an important role in promoting the development of the temporary prescription preparations.To promote the normalization,standardization and intelligent development of temporary prescription preparations,we would comprehensively summarize the significance,policy,technology characteristics,technology research status quo and existing problems in this paper,and put forward the research direction of temporary prescription preparation technology based on the physical properties of raw materials,equipment research strategy,and intelligent manufacturing technology.Thus it will push the inheritance and innovation of temporary prescription preparation.

With lubricant and bonding effect simultaneously, wetting agent has direct effect on properties of wet mass and extrudate, thus affecting the forming quality of pellets in extrusion-spheronization process. In this research, 25 representative kinds of traditional Chinese medicine(TCM) were selected as model drugs and 20%, 30% and 40% drug loading were set with MCC as their balling agent. The torque rheological curves were measured to get parameters such as maximum torque (Tmax) and corresponding water addition (WTmax) for these 75 raw materials by a mixer torque rheometer (MTR).The results showed that among 75 representative raw materials, 74 ones could be obtained for spherical pellets under the water addition of WTmax-2. corresponding to the second largest torque in torque rheological curve, suggesting that MTR could be used to select the optimal wetting agent dosage of TCM pellets. So the tedious and expensive pre-production work could be considerably reduced when TCM pellets were prepared.
RESUMO
Traditional processes are mostly adopted in traditional Chinese medicine (TCM) preparation production and the quality of products is mostly controlled by terminal. Potential problems of the production in the process are unpredictable and is relied on experience in most cases. Therefore, it is hard to find the key points affecting the preparation process and quality control. A pattern of research and development of traditional Chinese medicine preparation process based on the idea of Quality by Design (QbD) was proposed after introducing the latest research achievement. Basic theories of micromeritics and rheology were used to characterize the physical property of TCM raw material. TCM preparation process was designed in a more scientific and rational way by studying the correlation among enhancing physical property of raw material, preparation process and product quality of preparation. So factors affecting the quality of TCM production would be found out and problems that might occur in the pilot process could be predicted. It would be a foundation for the R&D and production of TCM preparation as well as support for the "process control" of TCMIs gradually realized in the future.
