Objective: To establish a flow-through cell method for determining the release rate of bupivacaine multivesicular liposomes, and to explore the release mechanism of the multivesicular liposomes. Methods: Phosphate buffer solution (pH 7.0, containing 1% bovine serum albumin) was used as the release medium, with a volume of 100 mL. A dialysis tube with a molecular weight cut-off of 100 kDa was used in conjunction with a 22.6 mm tablet cell. The water bath temperature was maintained at 25 ℃. The flow rate was 16 mL · min^-1.The model-dependent methods were applied to fit the release curves of bupivacaine multivesicular liposomes produced by different manufacturing processes, to compare the similarity of the release curves, and to explore the release mechanism of the multivesicular liposomes. Results: The BiDoseResp mathematical model provided a good fit for the release curves of the three preparations produced by different manufacturing processes. Statistical analysis showed that the variances of the mean values for parameters A2 and h2 among the three preparations are homogeneous (P=0.391 > 0.05,P=0.151 > 0.05). The LSD test in multiple comparisons revealed that there was no significant difference in parameter A2 between batch 1 and the original product, while there were significant differences in parameter A2 between batch 2 and both the original product and batch 1 (P < 0.05). However, there were no significant differences in parameter h2 among the three preparations. The release of bupivacaine in liposomes involved both diffusion and erosion processes. As the drug was released from the liposomes, the liposomes themselves underwent structural rearrangement and dissolution. Conclusion: The flow-through cell method for determining the release rate of bupivacaine multivesicular liposomes is established, and its release curves can reflect the release characteristics of multivesicular liposomes. It can also preliminarily distinguish the release behavior of multivesicular liposomes produced by different manufacturing processes. This method provides a reference for the screening of generic drug quality control and consistency evaluation.

Objective：Taking the active pharmaceutical ingredient A as an example, the risk assessment methods and strategies for reducing the microbial limit tests quantity were studied. Methods：By using a data model based on the Poisson distribution, the probability of misjudgment of results under different test amounts was simulated, and the impact of reducing the test quantity on the accuracy of the test results was analyzed. Different influencing factors and scoring rules were set for two dimensions: the quality stability of the active pharmaceutical ingredient and the degree of its impact on the pharmaceutical preparation. A risk assessment strategy was proposed to evaluate the microbial contamination risk of the active pharmaceutical ingredients. Results and Conclusion：When the manufacturing process of the active pharmaceutical ingredient A was stable and controllable, a test quantity of 10 mg could be used for accurate result judgment, which could meet the requirements for identifying and controlling the microbial contamination risk of this active pharmaceutical ingredients. The evaluation methods and strategies used in this paper can help determine the test quantity and test method when the microbial limit tests quantity of raw materials cannot meet the requirements of the pharmacopoeia.
