OBJECTIVE To investigate the key factors and directions for construction of a standard system for microbial control of pharmaceutical excipients. METHODS The contents related to pharmaceutical excipient microbial control including general requirements and monographs of standards in Chinese Pharmacopeia, United States Pharmacopeia and European Pharmacopeia were extracted and analyzed in combination with the current industrial status. RESULTS The included pharmacopoeias exhibit considerable differences in the coverage of pharmaceutical excipients and requirement for microbial control and there is still a lack of scientific and systematic guiding standards. The industrial requirements are yet to be met in terms of testing methodology, standardization, and instruction. CONCLUSION Attention should be paid to the methodological research and risk management of microbial control of pharmaceutical excipients. Instructive standards for microbial control of pharmaceutical excipients should be developed based on comprehensive consideration of excipient features and intended use with formulation as a core, to improve the quality standard system of pharmaceutical excipients and ensure drug safety.
