Establishment of Microbial Limit Test for Hospital Preparation ‘Compound Alum Powder’

Abstract

Background: the assessment of microbiological quality of medicinal products is one of control stages in medicinal products saft, because the holder of a manufacturing authorization must drug so as to ensure that they are fit for their intended use, comply with the requirements of the Marketing Authorization and do not place patients at risk due to inadequate safety, quality or efficacy. Objective: To assess microbial limit test for hospital preparation ‘compound alum powder’. Methods: The results of strain culture and analysis were used to evaluate the drug quality of ‘compound alum powder’. The objective is ‘compound alum powder’ (approval number: Z20140229) was made by the First Affiliated Hospital of Jinan University. Their batch numbers include: 201019, 200818, 200701. Validation tests were carried out in accordance with the standards of the Chinese Pharmacopoeia (2020 edition). Three parallel independent validations were conducted to calculate the recovery rate of each test bacterium and investigate whether each test bacterium was detected in the control bacterial inspection. Result: The recovery ratio of the total number of aerobic bacteria, molds and yeast in the control group was in the range of 0.5 ~ 2, and the results of the control group were positive, and the results of each control group met the requirements. The results show that the membrane filtration method is suitable for the microbial limit test of ‘compound alum powder’. Conclusion: this microbial limit test method control and ensure the quality of drug production by solving the problem of interference of antimicrobial components in drugs. It can eliminate the bacteriostasis of boric acid, phenol and alum.
