本文对于药物相容性的研究,有非常重要的实际应用价值。它对于今后对药物包材的相容性实验具有指导意义。由于相容性的研究越来越受到重视,但是国内研究较少,缺乏参考。
摘要:采用高效液相法测定注射液用药物包装材料中2,6-二叔丁基对甲酚(BHT)、3-(3,5-二叔丁基-4-羟苯基)丙酸(抗氧剂1076)、四 [3-(3, 5-二叔丁基-4-羟苯基) 丙酸]季戊四醇酯(抗氧剂1010)、三[2.4-二叔丁基苯基]亚磷酸酯(抗氧剂168)及其降解产物四溴苯酐(TBPA)、2,4-二叔丁基苯酚(DBP)、苯酚(Phe)和硫(S)的含量,并考察抗氧剂在注射液中的迁移情况和溶出情况。采用(Waters ACQUITY UPLC BEH C8 2.1*150mm,1.7 µm)色谱柱;柱温:35 ℃;进样量:2 uL;PDA检测器:检测波长270nm流动相:A相为乙腈,B相为水。各抗氧剂在其对应的浓度范围内呈线性,线性关系良好(r=0.9964),平均回收率88.3%~130%。精密度、准确度、稳定性均符合《中国药典》规定。各批次样品中均未检出有抗氧剂成分。本方法方便、可靠、灵敏,可用于注射液用药品包装材料中抗氧剂的含量及迁移量和溶出量的测定。

Determination of hazardous substance like Antioxidants in medicinal infusion packaging materials
Abstract: To establish a HPLC method for determination of 2,6-Di-tert-butyl-4-methylphenol(BHT),3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid (antioxidant 1076),Tetra [3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid] pentaerythritol ester (Antioxidant 1010),Tris[2.4-di-tert-butylphenyl] phosphite( antioxidant 168) and their degradation products of Tetrabromophthalic anhydride(TBPA),2,4-Di-tert-butylphenol(DBP) ,Phenol (PHE) and S in medicinal infusion packaging materials, and investigate the migration of the antioxidants from the materials to the injection and the digestion of the antioxidants from the injection to the materials. The separation of antioxidants was performed on a Waters ACQUITY UPLC BEH C8(2.1*150mm,1.7 µm)chromatographic column at 35 ℃ and the detection wavelength was set at 270nm.The mobile phase A is acetonitrile and the mobile B is water, and the injection volume was 2 uL. The antioxidants showed good linear relationship in range of their own concentration(r=0.9966).The average recovery was in the range of 88.3%~130%. Precision,stability,repeatability are in line with Chinese Pharmacopoeia. The antioxidants was not detected in each batch of samples. This method is convenient, reliable and sensitive and it can be used for the determination of antioxidants in medicinal infusion packaging materials and the migration of the antioxidants from the materials to the injection and the digestion of the antioxidants from the injection to the materials.

1.1 引言
每个人都会得大大小小的疾病,所以药物是人类生活的必需品,药物安全的保障是非常关键的一环。近几年,国家药品监管局越来越重视药物相容性方面的研究,各个药品开发及生产的企业也越来越关注和了解这方面的研究。对药物相容性的不断研究,可以满足国家对药品安全问题[ 1 ]的提出,还可以为许多药品生产开发企业提供技术支持。
