Expert consensus on the design and implementation of clinical safety centralized monitoring study of Chinese medical injection / 中国中药杂志

Along with the increase of clinical application, the safety of traditional Chinese medicine gained more and more attentions. In particular, the safety evaluation of Chinese medical injections has become a mandatory task should be completed by pharmaceutical companies under the supervision of China Food and Drug Administration(CFDA). Due to the weak foundation of previous studies, the safety issues of Chinese medical injections have not been fully understood, and lack of scientific and rational risk management programs. Clinical safety centralized monitoring(CSCM) is an important method for post-market safety evaluation of Chinese medicine. Due to the lack of appropriate norms and procedures, the quality of similar research is uneven, and the results vary. Combined with practical experience with experts' suggestions, we developed this expert consensus on the design and implementation of CSCM from three stages (design, implementation and report) with 20 technical points, which will provide technical support for future CSCM studies.

Establish research model of post-marketing clinical safety evaluation for Chinese patent medicine / 中国中药杂志

The safety of Chinese patent medicine has become a focus of social. It is necessary to carry out work on post-marketing clinical safety evaluation for Chinese patent medicine. However, there have no criterions to guide the related research, it is urgent to set up a model and method to guide the practice for related research. According to a series of clinical research, we put forward some views, which contained clear and definite the objective and content of clinical safety evaluation, the work flow should be determined, make a list of items for safety evaluation project, and put forward the three level classification of risk control. We set up a model of post-marketing clinical safety evaluation for Chinese patent medicine. Based this model, the list of items can be used for ranking medicine risks, and then take steps for different risks, aims to lower the app:ds:risksrisk level. At last, the medicine can be managed by five steps in sequence. The five steps are, collect risk signal, risk recognition, risk assessment, risk management, and aftereffect assessment. We hope to provide new ideas for the future research.

Safety and risk factor analysis on Polygoni Multiflori Radix base on ancient traditional Chinese medicine literatures / 中国中药杂志

Traditional Chinese medicine Polygoni Multiflori Radix is dried roots of Polygonaceae Polygortum multiflorum Thunb. Its clinical application records were first discovered in literatures of the Tang dynasty. The origins, efficacy, toxicity, processing and taboos of Polygoni Multiflori Radix have been discussed in many ancient herb literatures. In recent years, with the increase in the public awareness in health, Polygoni Multiflori Radix admits preparations have been more widely applied in the treatment and prevention of diseases. However, there have been more and more reports about Polygoni Multiflori Radix induced liver injury, the safety of Polygoni Multiflori Radix has increasingly attracted attention of the society. In this paper, the authors summarized and analyzed the toxicity and medication risk factors of Polygoni Multiflori Radix recorded in ancient herb literatures, and proposed that more attention shall be given to the effect of the planting and processing methods on the components and toxicity of Polygoni Multiflori Radix in safety studies, which provides clues for the further studies.

Enlightenment of adverse reaction monitoring on safety evaluation of traditional Chinese medicines / 中国中药杂志

The adverse reaction monitoring is important in warning the risks of traditional Chinese medicines at an early stage, finding potential quality problems and ensuring the safe clinical medication. In the study, efforts were made to investigate the risk signal mining techniques in line with the characteristics of traditional Chinese medicines, particularly the complexity in component, processing, compatibility, preparation and clinical medication, find early risk signals of traditional Chinese medicines and establish a traditional Chinese medicine safety evaluation system based on adverse reaction risk signals, in order to improve the target studies on traditional Chinese medicine safety, effective and timely control risks and solve the existing frequent safety issue in traditional Chinese medicines.

Opportunity and challenge of post-marketing evaluation of traditional Chinese medicine / 中国中药杂志

Post-marketing evaluation is a process which evaluate the risks and benefits of drug clinical application comprehensively and systematically, scientific and systematic results of post-marketing evaluation not only can provide data support for clinical application of traditional Chinese medicine, but also can be a reliable basis for the supervision department to develop risk control measures. With the increasing demands for treatment and prevention of disease, traditional Chinese medicine has been widely used, and security issues are also exposed. How to find risk signal of traditional Chinese medicine in the early stages, carry out targeted evaluation work and control risk timely have become challenges in the development of traditional Chinese medicine industry.

Advance in studies on toxicity of aristolochic acid and analysis on risk factors / 中国中药杂志

The renal toxicity and mutagenicity of aristolochic acid (AA) as well as its carcinogenicity on upper urinary tract transitional epithelial cells have been widely known. Since 2003, drug regulatory departments have successively cancelled the quality standards for AA-containing medicines such as Aristolochiae Radix, Aristolochiae Manshuriensis Caulis and Aristolchiae Fangchi Radix, and adopted measures for strengthening regulation and revising package insert or quality standards for other AA-containing medicines, including Aristolochia Cinnabarina Radix, Aristolochiae Fructus, Aristolochiae Mollissimae Herba, in order to control its safety risk. In recent years, domestic and foreign studies on AA have mainly involved action mechanism and clinical performance of AA toxicity, early-stage diagnosis and treatment method. In this paper, authors gave a brief summary and evaluation on risk factors for using AA-containing medicines, and offered measures and suggestions for preventing and controlling AA toxicity.
