Interpretation of Technical Specifications for Revision of Safety Information in Marketed Chinese Patent Medicine Instructions / 中国中药杂志

Technical Specifications for Revision of Safety Information in Marketed Chinese Patent Medicine Instructions,a series of group standards,were proposed by Professor ZHANG Bing from Research Center for Pharmacovigilance and Rational Use of Traditional Chinese Medicine,and underwent centralized management by Chinese Association of Chinese Medicine. They were officially released on July 23 and implemented on July 31,2021. The series of group standards consist of six sections,including general principles,adverse drug events,contraindications,precautions,application for special populations,and warnings. The section of general principles is comprised of holistic and programmatic expressions,which explain the general technical requirements for revising the marketed Chinese patent medicine instructions. The other five sections focus on information collection,screening,transformation,and illustration of specific items,forming a standardized revision technical process. This series of standards is the result of multiple rounds of research and the suggestions of more than 200 experts in different professional fields of " medicine-pharmacy-management-law-enterprise" have been gathered therein to reach a consensus. With the purposes of establishing standardized technical specifications for the revision of safety information in the marketed Chinese patent medicine instructions,guiding marketing authorization holders in revising the instructions,filling the gaps in the research of Chinese patent medicine instructions,promoting the deve-lopment of pharmaceutical care and academic research,and encouraging the rational and safe medication of Chinese patent medicine,the series of group standards is of great significance.

Drug instructions,the statutory and technical documents recording effectiveness and safety information,are an important basis for guiding doctors,pharmacists,and patients to use drugs rationally,and their scientificity,standardization,and accuracy directly affect the medication safety of the public. The sections of adverse drug events,contraindications,precautions,warnings,and application for specific populations in drug instructions directly express safety information and measures for rational use of drugs. In the drug life cycle,marketing authorization holders( MAHs) need to update safety information in the instructions promptly to ensure the safety and effectiveness of clinical drug medication. At present,revising instructions is an important measure to control drug risks. In the drug life cycle,in order to standardize the revision of safety information in the instructions by MAHs and eliminate inexact terms such as " unclear",the Technical Specifications for Revision of Safety Information in Marketed Chinese Patent Medicine Instructions,a series of group standards,have been established under the guidance of Standardization Department,China Association of Chinese Medicine. Therefore,on the basis of the existing rules and regulations,the standardized technical procedures for revising instructions came into being to help clinical safe and rational medication of drugs,and implement the strategy of " Healthy China".

In order to solve the problems of confusion in clinical medication and imperfect instructions in Chinese patent medicines(CPMs), the Standardization Department of the China Association of Chinese Medicine and Center for Pharmacovigilance and Rational use of Chinese Medicine in Beijing University of Chinese Medicine jointly compiled the Instructions for Clinical Application of Chinese Patent Medicines(CPMs). As the interpretation and supplement of drug instruction information, it aims to guide clinical safety and rational use of CPMs. In addition, the technical specification for clinical application description of CPMs has been formulated, which covers the seven processes of "carding instructions, clinical investigation, data retrieval, data screening, evidence classification, path transformation and writing format". It will enable readers of Instructions for Clinical Application of Chinese Patent Medicines to understand the work behind the compilation.

Pharmacovigilance study on drug-induced cardiac injury during treatment of COVID-19 / 中国中药杂志

Because coronavirus disease 2019(COVID-19) is highly contagious and serious, it has posed a major threat to public health worldwide. The curative effects of integrated traditional Chinese medicine and Western medicine in the treatment of COVID-19 have been widely recognized and confirmed. However, medical workers shall pay attention to drug-induced heart injury in clinical application. Based on the guideline from the Diagnosis and Treatment Plans for COVID-19(trial seventh edition), taking the recommended drugs as examples, by Western medicine, traditional Chinese medicine, Chinese herbal injection and integrated traditional Chinese and Western medicine, the study analyzed the basic characteristics of recommended drugs for cardiac injury by means of literature review and bioinformatics methods, and summarized cardiac adverse reactions, toxicity mechanisms, combined pharmacotherapy, special population and drug monitoring, focusing on the clinical manifestations, toxic components, targets and regulatory mechanisms of drug-induced cardiac injury. The findings suggested being vigilant to drug-induced cardiac injury during the treatment of COVID-19, playing the advantages of clinical pharmacists and clinical Chinese pharmacists, improving the knowledge reserve of pharmacovigilance, strengthening the prescription review, medication notification and medication monitoring, promoting rational drug use and paying attention to special populations and high-risk groups. The study aims to provide suggestions and reference for pharmacovigilance and pharmaceutical care for front-line doctors and pharmacists against COVID-19, in order to avoid the occurrence of drug-induced heart injury for patients with COVID-19.

Benefit and risk of Tripterygium Glycosides Tablets in treatment of rheumatoid arthritis based on multi-criteria decision-making analysis / 中国中药杂志

Rheumatoid arthritis(RA) has a high disability rate and is highly harmful. It has a long course of treatment and is prone to adverse reactions or events(ADR/ADE). Selection of drugs in particular shall give consideration to both benefits and risk. Tripterygium Glycosides Tablets(TGT) is one of the important drugs for the treatment of RA. It has a remarkable efficacy, but a strong toxicity, which is controversial in clinical use. The study was oriented to patients, and quantitatively evaluated the efficacy and risk of TGT in treatment of RA, providing an intuitive basis for clinical safety and effective application of TGT. A multi-criteria decision-making analysis(MCDA) model of TGT was built in the treatment of RA, and then benefit and risk indicators were weighted by SWING method. Totally 53 random clinical trials(RCT) in accordance with the evaluation criteria were included by Meta-analysis method. The RCT results were merged by Meta-analysis, indicating that compared with the conventional therapy of chemical immunosuppressant(CISD), TGT could improve the curative effect whether it was used alone or in combination with CISD, but it would increase the incidence of reproductive system damage. The combined administration with CISD would also increase the incidence of liver and kidney damages. Treatment outcomes varied according to the different conditions of the combined administration with CISD. Based on MCDA model and clinical results, the benefit value, risk value and benefit-risk value of different doses, courses and combined administration of TGT in the treatment with RA were compared. The results showed that when the benefit and risk of the drug were equally important to the patient, the benefit-risk value of the single administration of TGT was 59, while that of the combined administration of TGT and CISD was 39. Therefore, the benefit-risk value of the single administration of TGT was 100% better than the combined administration. When the combined administration of TGT and CISD is unavoidable, the benefit-risk value of low-dose TGT(0.10-0.99 mg·kg~(-1)·d~(-1)) was 48, while that of high-dose TGT was 36. Therefore, low-dose TGT combined with CISD was more easily accepted by patients. The 2 to 3-month treatment course had a benefit-risk value of 40, while the long treatment course had a benefit-risk value of 38. Based on existing evidences, the single administration of TGT may be better than the combined administration with CISD. If the patients need to combine with CISD to treat RA, low dosage and 2 to 3-month course may be relatively optimal.
