RESUMEN
Amid the modernization and internationalization of traditional Chinese medicine(TCM), the safety of TCM has attracted much attention. At the moment, the government, scientific research teams, and pharmaceutical enterprises have made great efforts to explore methods and techniques for clinical safety evaluation of TCM. Although considerable achievements have been made, there are still many problems, such as the non-standard terms of adverse reactions of TCM, unclear evaluation indicators, unreasonable judgment methods, lack of evaluation models, out-of-date evaluation standards, and unsound reporting systems. Therefore, it is urgent to further deepen the research mode and method of clinical safety evaluation of TCM. Based on the current national requirements for the life-cycle management of drugs, this study focused on the problems in the five dimensions of clinical safety evaluation of TCM, including normative terms, evaluation modes, judgment methods, evaluation standards, and reporting systems, and proposed suggestions on the development of a life-cycle clinical safety evaluation method that conformed to the characteristics of TCM, hoping to provide a reference for future research.

With the rapid development of nanotechnology, the research and development of nanomedicines have become one of the development directions of drug innovation. Nanomedicines have special physical and chemical properties, such as nanoscale effects and nanostructure effects, so they have special biological properties, which may change the pharmacokinetic profiles such as absorption and tissue distribution of drug molecules, and thus affect their safety and effectiveness. There are many special concerns on the non-clinical safety evaluation of nanomedicines at the basis of ordinary drug because of the particularity of nanomedicines. On August 25, 2021, China issued Guidance on Non-clinical Safety Evaluation for Nanomedicines(interim). This article interprets comprehensively the guidance, focuses on the key points of non-clinical safety evaluation for nanomedicines, and expounds combined with some cases, aiming to provide reference for drug researchers.
RESUMEN
At present,the various levels of safety evaluations of traditional Chinese medical (TCM) injections were in force in post-marketing clinical researches,while the process quality is guaranteed with difficulty.Therefore,it is requisite to call for technical guidance.By drawing lessons from the international experience of drug marketing safety evaluation and the related methods,we proposed the key techniques of quality control for clinical safety evaluation of TCM injections from the three aspects:preparation,implementation and summarization of researches,combining with the characteristics of TCM injections.The key techniques contained some scientific problems,ethics,publicity,data management,statistical analysis,specification report,etc.This paper comprehensively introduced the requisite technologies and methods over research quality,laying a foundation for the studies of post-marketing clinical safety evaluation of TCM injections.
RESUMEN
Safety,efficacy and quality control are the three essential elements for drugs,including traditional Chinese medicine(TCM). Currently,rapid development of life sciences,medicine and phar?macy provides new prospects for TCM. Considering the long history of TCM application,modern phar? macology and toxicology, global standards and expectations on the safety of TCM, how to evaluate the safety of TCM scientifically has become a key to the research and development of TCM. This review aims to discuss current technical requirements of non-clinical safety study of TCM as well as the challenges.
RESUMEN
There is an increasing demand for neonatal and juvenile animal toxicity studies during the research and development of new drugs. In this paper,we discussed general evaluation parameters of pediatric non-clinical safety with pediatric drugs,such as growth and development and food intake,and paramenters of other organs and systems, such as the central nervous system,reproductive system, behavior evaluation in combination with our own experience. In addition,the characteristics of non-clin?ical safety evaluation of new traditional Chinese medicine materia medica used for juvenile animals were analyzed. This paper is intended reference for non-clinical safety evaluation of pediatric drugs and to gain some experience related to formulation of new guidelines.
