Good And Appropriate Chemical Stability

- Mar 23, 2018 -

The glass containers used to hold various kinds of medicines should have good compatibility with the drugs, that is, it must be ensured that in the production, storage and use of drugs, the chemical properties of the glass containers cannot be unstable, and certain substances between them will occur. The chemical reaction caused a variation or failure of the drug. For example, high-grade drugs such as blood preparations and vaccines must be made of glass containers made of borosilicate glass, and various kinds of strong acid and alkaline aqueous needle preparations, especially strong alkali injections, should also be made of borosilicate glass. At present, the low-borosilicate glass ampoules used in China are not suitable for containing water-needle preparations. This kind of glass materials should be gradually transitioned to the 5.0-glass material in order to meet the international standards as soon as possible to ensure that the medicines they contain are not used during use. Stripping, no turbidity, no deterioration. For general powder injections, oral drugs and large infusions and other drugs, the use of low-borosilicate glass or neutralization of soda-lime glass can meet the chemical stability requirements. The degree of erosion of drugs for glass is generally liquid is greater than solids, alkaline than acidic, in particular, the injection of strong alkali aqueous injection agent with higher chemical properties.
