Based on the defects in powder properties of the contents of Ziyin Yiwei Capsules, this study screened out the main medicinal slice powders causing the poor powdery properties, and introduced the powder modification process to improve the powdery properties of these slice powders, the pharmaceutical properties of the capsule contents, and the content uniformity of Ziyin Yiwei Capsules, so as to provide a demonstration for the application of powder modification technology to the preparation of Chinese medicinal solid preparations. Through the investigation on the powder properties of the contents of Ziyin Yiwei Capsules, it was clarified that the pulverized particle size of the capsule contents had a good correlation with the pulverization time. According to the measurement results of the powder fluidity and wettability, the quality defects of the capsule contents were caused by the fine powders of Taraxaci Herba and Lungwortlike Herba. "Core-shell" composite particles were prepared from medicinal excipients magnesium stearate and fine powders of Taraxaci Herba and Lungwortlike Herba slices after ultra-fine pulverization to improve the powder properties of the problematic fine powders. Powder characterization data including fluidity and wettability were measured, followed by scanning electron microscopy(SEM) and infrared ray(IR) detection. It was determined that the optimal dosage of magnesium stearate was 2%, and the compositing time was 3 min. The composite particles were then used as content components of the Ziyin Yiwei Capsules. The powder characteristics between the original capsule and the modified composite capsule including the particle size, fluidity, wettability, uniformity of bulk density, and uniformity of chromatism as well as the content uniformity and in vitro dissolution were compared. The results showed that the powder characteristics and content uniformity of the prepared composite capsule were significantly improved, while the material basis of the preparation was not changed before and after modification. The preparation process was proved to be stable and feasible. The powder modification technology solved the pharmaceutical defects that were easy to appear in the preparation of traditional capsules, which has provided experimental evidence for the use of powder modification technology for improving the quality of Chinese medicinal solid preparations and promoting the secondary development and upgrading of traditional Chinese medicinal dosage forms such as capsules.

Three kinds of excipients were selected to investigate the anti-bitterness effect on the extremely bitter characteristics of Andrographis Herba decoction, and the optimal combined anti-bitterness formula was obtained. The preparation principle of different excipients was clarified by virtual screening and experimental verification to explore the advantages of the three kinds of excipients in the combined anti-bitterness effect. Sensory evaluation showed that mPEG_(2000)-PLLA_(2000), γ-cyclodextrin(γ-CD), and aspartame all had good anti-bitterness effect, which reduced the bitterness intensity of Andrographis Herba decoction by 0.5, 6, and 3 points, respectively. The anti-bitterness effect was superior when 0.15% mPEG_(2000)-PLLA_(2000), 1.60% γ-CD, and 0.04% aspartame were combined, and the taste score of the Andrographis Herba decoction decreased from 8 points(severe bitterness) to 1 point(almost no bitterness). Quantum chemistry calculations showed that mPEG_(2000)-PLLA_(2000) reduced the electrostatic potential of bitter groups, which spontaneously combined with it and formed a physical barrier, hindering the binding of bitter components to receptors. The interaction between γ-CD and bitter components was studied. It was found that the surface area and free energy of γ-CD decreased and the dipole moment increased, indicating that γ-CD included bitter components and self-assembled to form supramolecules. Molecular docking showed that hydroxy at position 14 and carbonyl at position 16 of andrographolide, and hydroxy at position 3 and 4, carbonyl at position 14, and five-membered lactone ring of dehydrated andrographolide were possibly the main bitter groups. The binding free energies of aspartame to bitter receptors TAS2 R10, TAS2 R14, and TAS2 R46 were-3.21,-1.55, and-2.52 kcal·mol~(-1), respectively, indicating that aspartame competed to inhibit the binding of bitter groups to bitter receptors. The results of content determination showed that the free amounts of andrographolide and dehydrated andrographolide in Andrographis Herba decoction were 0.23% and 0.28% respectively, while after adding flavor masking excipients, the dissociation amount of andrographolide and dehydrated andrographolide in the decoction decreased to 0.13% and 0.20%, respectively. The above results show that mPEG_(2000)-PLLA_(2000) involves some bitter components into it through micellar self-assembly to reconcile the entrance bitterness, and γ-CD includes the remaining bitter components in the real solution to control the main bitter taste. Aspartame further competes to inhibit the combination of bitter components and bitter receptors, and improves the taste to be sweet. Multi-excipients combined with anti-bitterness strategy significantly reduces the free concentration of bitter substances in Andrographis Herba decoction, and optimizes the taste of the decoction.

Oral solid dosage(OSD) occupies a key position in the market of Chinese patent medicines and new traditional Chinese medicines. Processing route is the foundation for the research and development of traditional Chinese medicine OSDs. On the basis of prescriptions and preparation methods of 1 308 traditional Chinese medicine OSDs recorded in the Chinese Pharmacopoeia, we summarized the patterns of processing routes of both modern dosage forms(tablets, granules, and capsules) and traditional dosage forms(pills and powder) and constructed a manufacturing classification system(MCS) based on the processing routes. Based on the MCS, statistical analyses were conducted respectively on medicinal materials, pharmaceutical excipients, extraction solvents in the pretreatment process, crushed medicinal materials, methods of concentration and purification, and methods of drying and granulation, aiming to uncover the process features. The results showed that each dosage form can be prepared via different routes with different processing methods of decoction pieces and raw materials for dosage preparation. The raw materials for dosage form preparation of traditional Chinese medicine OSDs included total extract, semi-extract, and total crushed powder, which accounted for different proportions. The raw materials for traditional dosage forms are mainly decoction pieces powder. Semi-extracts are the main raw materials for tablets and capsules, which account for 64.8% and 56.3%, respectively. Total extracts are the main raw materials for granules, with a proportion of 77.8%. Compared with tablets and capsules, traditional Chinese medicine granules with dissolubility requirements had a larger proportion of water extraction process, a higher proportion of refining process(34.7%), and a lower proportion of crushed medicinal mate-rials in semi-extract granules. There are four ways to add volatile oil to the modern dosage forms of traditional Chinese medicine. In addition, some new technologies and processes have been used in concentration, filtration, and granulation processes of traditional Chinese medicine OSDs, and the application of pharmaceutical excipients is diversified. The results of this study are expected to provide reference for the processing route design and upgrading of OSDs for new traditional Chinese medicines.

PURPOSE: To investigate the characteristics of the clear oil-drop residue observed in the vitreous cavity after intravitreal injection of different brands of triamcinolone acetonide (TA), and to compare this ingredient's effects in those products. METHODS: Intravitreal injections of four different brands of triamcinolone acetonide (4 mg/0.1 mL), which are commercially available in Korea, were given to 40 eyes for the treatment of macular edema due to a variety of causes from October 2005 through February 2006. Regular slit-lamp biomicroscopy of fundus had been performed periodically with digital image acquisition equipment after injection of TA for at least two months. We analyzed the characteristics of this residue and compared the number and size of this residue in each product. RESULTS: Four TA products commercially available in Korea were used, with vehicles composed of preservatives and suspending agents. There were differences between products in respect to ingredients and content, as well as the characteristics of the intravitreal clear oil droplet-like residue. CONCLUSIONS: Each TA product has a variable frequency and variable amounts of clear oil droplet-like residue, which seems to be a component of the vehicle. This variation could generate differences in efficacy, side effects, and retaining duration. It should be verified whether commercial TA products are consistently safe and effective.

Commercially available japonica rice and indica rice with different trade names were collected,and then based on the method of rice stir-frying,their many indexes were evaluated,for example the physical and chemical properties such as appearance color,grain type,broken kernel ratio,length-width ratio,1 000-grain weight,specific heat capacity,moisture content,amylose content,and protein content. The discriminant function analysis was used to determine the effective factors affecting the quality of rice as excipients. The results showed that two types of rice could be distinguished by rice color parameter a*,grain parameter circularity,1 000-grain weight and amylose content. These four effective factors can be used as the quality evaluation indexes for fried rice as excipients.Protein is one of the main components of rice,and its content affects the quality of rice. There is a significant difference in the protein content between japonica rice and indica rice. Therefore,protein content should be used as one of the evaluation indexes for rice quality. After comprehensive consideration,it is suggested that the red-green value a*shall not be less than 0. 50; the circularity not less than 53. 0,the 1 000-grain weight not less than 16. 0 g,the amylose content not less than 12. 0% and the protein content not less than4. 0% in the japonica rice; the red-green value a*shall not be lower than-1. 0,the circularity not less than 41. 0,the 1 000-grain weight not less than 13. 0 g,the amylose content not less than 9. 0% and the protein content not less than 3. 5% in the indica rice. In this study,the quality evaluation standards for rice as excipients( japonica rice,indica rice) were supplemented and improved,laying foundation for the development of quality standards for rice as excipients with the rice stir-frying method.
