    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.

    Objective: To analyze the registration history of traditional Chinese medicine (TCM) generic drugs and the registration application in the past 20 years, explore the development status of medicine with the same name and prescription, and to provide reference for their development. Methods: A systematic analysis was conducted on the changes in the registration policies of TCM generic drugs in China, as well as the general situations such as the registration applications and the approvals for production of TCM generic drugs or drugs with the same name and prescription from 2003 to 2024. The evolution of the registration policy of TCM generic drugs, the characteristics of registration declaration in each stage, and the risks and opportunities of research and development of the medicine with the same name and prescription were discussed. Results: From 2003 to 2024, the registration applications and the approvals for production of TCM generic drugs or medicine with the same name and prescription had obvious policy-driven characteristics, showing a clear three-stage evolutionary process. From 2003 to 2006, there was a rapid increase in the number of registration applications and approved production for “generic standards” with low entry barriers. From 2007 to 2021, there was a high entry barrier for “generic varieties”, and the number of registration applications and approvals plummeted and continued to be low. With the announced of the “medicine with the same name and prescription” in 2020 and the advancement of relevant regulations, both registration applications and approvals have gradually recovered. However, it has not been active since 2022. As of 2024, there have been 6 registration applications for the same name and prescription, with 1 of them approved for market launch. Conclusion: The concept of drugs with the same name and prescription is different from that of generic drugs. Although it has the meaning of the generic drug in chemical medicine, it represents a qualitative improvement in the concept of TCM generic drugs. Currently, the registration applications of drugs with the same name and prescription are mainly for individual varieties. However, in the long term, there may be some regular development model. From the perspectives of variety selection, clinical trials and research risks, the development of drugs with the same name and prescription presents both opportunities and risks.
