Standard application of medicinal glass bottles

All kinds of products and different materials form a standard system, which provides sufficient basis and conditions for selecting scientific, reasonable and appropriate glass containers for all kinds of drugs.

The following principles should be followed in the selection and application of various medicines with different dosage forms, properties and grades:

Chemical stability

Good and suitable chemical stability principle

The glass containers used for holding all kinds of drugs should have good compatibility with the drugs, that is, the production, storage and use of drugs should not be unstable because of the chemical properties of the glass containers, the chemical reaction between some substances will not lead to drug variation or failure.

The erosion degree of medicine to glass is generally liquid is greater than solid, alkalinity is greater than acid, especially strong alkali water injection has higher requirements on the chemical performance of medicinal glass bottle.

Temperature resistance to abrupt change

Good and suitable resistance to abrupt temperature change

Different dosage forms of drugs in the production of high temperature drying, disinfection and sterilization or low temperature freeze-drying process, which requires that the glass container has a good and appropriate resistance to temperature upheaval without cracking.

The temperature resistance of glass is mainly related to the coefficient of thermal expansion, the lower the coefficient of thermal expansion, the stronger the resistance to temperature change.

Mechanical strength

Good mechanical strength

Drugs of different dosage forms need to undergo certain mechanical impact resistance in the production process, transportation and loading and unloading. The mechanical strength of medicinal glass bottle containers is not only related to bottle shape, geometric size and thermal processing, but also influenced by glass material. The mechanical strength of borosilicate glass is better than that of sodium calcium glass.

The release and implementation of the new standards for medicinal glass bottles will play a positive role in establishing a perfect and scientific standardization system, accelerating the pace of integrating with international standards and international market, improving the quality of pharmaceutical packaging materials, ensuring the quality of pharmaceuticals, promoting the development of the industry and international trade.

Of course, like the whole pharmaceutical packaging material standard system, there are still many problems that need to be further improved and improved, especially to adapt to the rapidly developing pharmaceutical industry and the requirements of international market integration.

In the compilation, content and index of the standard, as well as the adoption of international standards and the degree of integration with the international market, it is necessary to carry out appropriate adjustment and supplement in the revision.
