痰热清注射液的稳定性研究及其与氨基糖苷类药物的配伍观察

目的:考察痰热清注射液的稳定性及其与氨基糖苷类的配伍。方法:利用光阻法测定痰热清注射液在5%葡萄糖注射液、10%葡萄糖注射液、0.9%氯化钠注射液、复方氯化钠注射液、5%葡萄糖氯化钠注射液中的不溶性微粒。采用高效液相色谱法测定痰热清注射液分别与5%葡萄糖注射液、0.9%氯化钠注射液配伍放置8 h内,配伍液中黄芩苷含量的变化,并比较配伍前、后pH的变化。模拟临床条件观察庆大霉素、异帕米星、依替米星与痰热清配伍后的情况。结果:痰热清注射液与上述5种输液配伍后,微粒数均有所增加。其中与5%葡萄糖注射液、0.9%氯化钠注射液配伍后pH和黄芩苷含量无显著性变化。痰热清注射液与氨基糖苷类配伍后均有可见物生成。结论:痰热清注射液在临床输液中应注意不溶性微粒。痰热清与氨基糖苷类存在配伍禁忌。

Study on Stability of Tanreqing Injection and Observation of its Compatibility with Aminoglycosides

Objective:To investigate the stability of Tanreqing injection and its compatibility with Aminoglycosides.Methods: The insoluble particles of Tanreqing injection in five kinds of infusion solution were detected respectively by light-blockage method.The contents of Baicalin in two mixed solutions within 8h were determined by HPLC respectively.And the appearance and pH value of the mixtures were compared with those before mixing.The changes after Tanreqing injection mixed with isepamicin,etimicin or gentamycin...
