聚乙烯塑料是人工合成的高分子化合物,具有不易破碎等特点,在医院制剂包装中已经得到了广泛地应用。但由于塑料容器所含成份较复杂,除含塑料外,还有增塑剂、稳定剂、抗氧剂及填料等,各种组分都有可能在外界条件影响下,进入包装的制剂中。因此,在临床应用时,并不能完全替代玻璃瓶作为包装容器。我们在观察用塑料瓶包装几种临床常用的制剂中,发现虫咬剂在用塑料瓶代替玻璃瓶包装时,
Polyethylene plastic is a synthetic polymer compounds, with the characteristics of not broken easily, in the hospital preparation packaging has been widely used. However, due to the complexity of the ingredients contained in the plastic containers, plasticizers, stabilizers, antioxidants and fillers, besides the plastic, may enter the packaging preparations under the influence of external conditions. Therefore, in clinical applications, and can not completely replace the glass bottles as a packaging container. We are observing several commonly used formulations of plastic bottles in the packaging, insect bites found in plastic bottles instead of glass bottles,
