摘 要 目的:考察枸橼酸咖啡因注射液与3种常用注射液的配伍稳定性。方法:将枸橼酸咖啡因注射液分别与5%葡萄糖注射液、0.9%氯化钠注射液和10%葡萄糖酸钙注射液进行配伍,放置于室温,分别在0 min、10 min、30 min、24 h考察性状、pH、渗透压、不溶性微粒,采用高效液相色谱法测定有关物质、咖啡因含量和5%葡萄糖注射液配伍中5-羟甲基糠醛的含量。结果:在上述条件下,性状、pH、渗透压、不溶性微粒、有关物质和含量均无明显变化,与5%葡萄糖注射液配伍中5-羟甲基糠醛无明显变化。结论:枸橼酸咖啡因注射液与5%葡萄糖注射液、0.9%氯化钠注射液和10%葡萄糖酸钙注射液配伍后的溶液在24 h内安全稳定。

ABSTRACT Objective: To investigate the compatibility stability of caffeine citrate injection with three commonly used injections. Methods: The caffeine citrate injection was mixed with 5% glucose injection, 0.9% sodium chloride injection or 10% calcium gluconate injection, respectively and the mixtures were kept at room temperature. Their properties, pH value, osmolality, and insoluble particles were investigated at 0 min, 10 min, 30 min, and 24 h after mixture, respectively and the contents of the related substances, caffeine and 5-hydroxymethylfurfural in 5% glucose injection were determined by high performance liquid chromatography. Results: Under the above-mentioned conditions, the properties, pH value, osmotic pressure, insoluble particles, related substances and the other contents showed no significant change. Conclusion: The caffeine citrate injection being compatible with 5% glucose injection, 0.9% sodium chloride injection or 10% calcium gluconate injection is stable and safe within 24 hours.

咖啡因是中枢神经系统兴奋药,通过刺激呼吸中枢、阻断腺苷受体和改善呼吸肌功能等发挥作用。其具有肺保护作用,可以减低早产儿呼吸暂停的发生危险,提高撤机成功率,同时具有脑保护作用[1],故枸橼酸咖啡因注射液是新生儿科非常常用的一种药物,主要可以用于治疗早产新生儿的原发性呼吸暂停。参照药用说明书,枸橼酸咖啡因注射液除静脉注射外,可与5%葡萄糖注射液、0.9%氯化钠注射液和10%葡萄糖酸钙注射液配伍后静脉滴注。枸橼酸咖啡因注射液临床疗效较好,并发症少,安全性高[2],有与5%葡萄糖注射液和0.9%氯化钠注射液配伍的报道[3-4],但无配伍稳定性的相关研究。……
