ABSTRACT Objective: To reduce the risk of secondary contamination of endotoxin in the manufacturing process for Gualoupi injection. Methods: The process at the decarbonization step for depyrogenation was optimized by using a titanium filter instead of a plate and frame filter used in the original process. Results: The content of endotoxin was reduced by more than 80% and all other quality indicators were in compliance after process optimization. Conclusion: Substitution of a titanium filter for a plate and frame filter can significantly reduce the risk of a secondary contamination of endotoxin at the decarbonization step and there is no negative effect on the quality of Gualoupi injection.

瓜蒌皮注射液是由瓜蒌皮作为药材,经过浓缩、提取等多步工艺所制成的中药注射剂。其可有效控制心绞痛、冠心病的发作,改善心肌缺血[1]。在药理机制上的研究表明该注射剂具有多种保护心肌缺血的活性成分,其保护作用呈多途径多靶点[2]。近年来在临床上的应用日益广泛,对心、脑、肺等多脏器的多种疾病的治疗都有显著疗效[3]。

瓜蒌皮注射液以中药材瓜蒌皮作为原料,经过多次的煎煮、乙醇沉淀、树脂交换、浓缩制成浓缩液,再经过热处理和过滤制成提取液,最后通过制剂工艺制成最终成品[4]。

由于瓜蒌皮注射液的原材料为瓜蒌皮中药材,生产工艺步骤繁杂,因此热原是其最重要的质量控制指标之一,在生产过程中,必须考虑热原的有效去除,以保证最终产品质量[5]。

在所注册的瓜蒌皮注射液生产工艺中,采用中药注射剂中常用的活性炭吸附法去除热原[6],在加入活性炭并進行热处理后,使用板框过滤进行脱炭,脱炭前后药液中的细菌内毒素含量采用定量法测定。……
