摘要:

根据《中华人民共和国药典》2020年版四部通则1145,降压物质检查是通过比较组胺对照品与供试品引起麻醉猫的血压下降程度,判定供试品中所含降压物质的限度是否符合规定的一项常见药品检验方法。当降压物质检查结果超过质量标准规定(out of specification,OOS),可能是由药品本身质量风险引起,也可能是源于检验过程中的错误操作。因此,开展OOS原因分析对于确认试验结果、评价药品质量尤为重要。降压物质检查采用猫作为实验动物,其稳定性相对于常规实验动物更差,且手术难度大、试验流程复杂,这些因素导致调查降压物质检查出现OOS原因的难度较大。通过查阅资料结合实际工作经验,本文主要通过以下5方面分析降压物质检查出现OOS的原因:(1)从标准判定、标准内容以及标准起草3个方面分析了药品标准对OOS的影响;(2)人员资质,包括岗前培训、试验操作是否遵循标准操作规程,以及仪器操作的能力;(3)猫作为降压物质检查所用实验动物,其生理特性、遗传背景及试验过程中出现的异常状态等因素;(4)标准品、试剂、受试物以及关键仪器多道生理信号仪;(5)包括动物麻醉、动静脉插管手术、给药、数据处理等试验操作。本文旨在为广大药品与生物制品检验同行,在分析药品降压物质检查过程中出现OOS的原因时,提供一些参考思路。

Abstract:

According to General Chapter 1145 of Division IV in the Chinese Pharmacopoeia (2020 Edition), the test for depressor substances is a common method for drug testing. It determines whether the level of depressor substances in a test sample complies with the specified standards by comparing the extent of blood pressure reduction in anesthetized cats induced by the histamine reference substance and the test sample. If an out-of-specification (OOS) result occurs in the test for depressor substances, it may be caused by inherent quality issues of the drug or errors in the testing process. Therefore, analyzing the causes of OOS is particularly important for confirming the test results and evaluating drug quality. Cats are used as experimental animals in the test for depressor substances. Compared with conventional laboratory animals, they are less stable, surgery procedures are more challenging, and the testing process is more complex. These factors make it more difficult to investigate the causes of OOS in this test. Based on a review of the literature and practical work experience, this article analyzes the causes of OOS in the test for depressor substances from the following five aspects: (1) an analysis of the impact of drug standards on OOS from three aspects: standard determination, standard content, and standard drafting; (2) personnel qualifications, including pre-employment training, compliance with standard operating procedures during experimental operations, and the ability to operate instruments; (3) factors related to cats, used as experimental animals in the test for depressor substances, including physiological characteristics, genetic background, and abnormal conditions during the experiment; (4) reference substances, reagents, test samples, and key instruments such as the multi-channel physiological signal instrument; (5) experimental operations including animal anesthesia, arterial and venous catheterization, drug administration, and data processing. This article aims to provide reference approaches for professionals engaged in the testing of pharmaceuticals and biological products when analyzing the causes of OOS in the test for depressor substances.
