The group standard Pharmacovigilance guidelines f.r clinical application of.Chinese patent medicines f.r mucosal administration was released on January 16, 2024, on the national group standards inf.rmation platf.rm by the Institute of.Basic Research in Clinical medicine of.China Academy of.Chinese medical Sciences and School and Hospital of.Stomatology of.Peking University, under the centralized management by the China Association of.Chinese medicine. The standard number is T / CACm 1563. 6-2024. It aims to propose key elements and specif. technical methods f.r saf.ty monitoring and reporting, signal identif.cation, risk assessment, and risk control based on the Drug administration law of.the People ' s Republic of.China (revised in 2019), which establishes normative pharmacovigilance guideline of.Chinese patent medicine f.r mucosal administration that is in line with the characteristics of.traditional Chinese medicine (TCm) based on the pharmacovigilance content f.r clinical application of.Chinese patent medicine f.r mucosal administration. The group standard has been discussed by internal and external experts through multiple rounds of.consultation. It serves as a guiding document f.r stakeholders involved in pharmacovigilance activities, including pharmaceutical license holders, drug manuf.cturers, medical institutions, research institutes, and pharmaceutical trading enterprises. © 2024 Zhongguo Zhongyi Yanjiuyuan.

Drug administration law of.the People′s Republic of.China (2019 revised edition), which came into ef.ect on December 1, 2019, proposed that " the state shall establish a pharmacovigilance system" . Pharmacovigilance work of.Chinese patent medicines is more dif.icult, and it is necessary to carry out Pharmacovigilance activities that are in line with the characteristics of.Chinese patent medicines. Pharmacovigilance guidelines of.Chinese patent medicines (T / CACm 1563. 1-2024), based on the principles of.Drug Administration Law of.the People′ s Republic of.China (2019 revised edition) and Pharmacovigilance quality management standards (No. 65 of.2021) of.the National medical Products Administration, draws on the EU Pharmacovigilance regulation and the secondary guidelines of.International Council f.r Harmonization of.Technical Requirements f.r Pharmaceuticals f.r Human Use (ICH), and it is draf.ed in accordance with the provisions of.Guidelines f.r standardization work part 1: structure and draf.ing rules of.standardization documents (GB / T1. 1-2020) based on the characteristics of.Chinese patent medicines.
