Problems solved by technology

First of all, the test has proved that under the condition of higher pH, the stability of ibuprofen injection decreases, which is manifested by the rapid increase of the amount of impurities, and the index of insoluble particles is unqualified
Secondly, the high-pH drug solution puts forward higher requirements on the ampoule. If the ampoule with low specifications is used, the compatibility of the packaging material will easily fail, pitting will appear on the inner surface of the ampoule, and the glass will fall off. Pb, Al, Se, Gr, Si and other metal elements in the glass material are leached out and enter the injection solution, causing great clinical risks
Finally, the high-pH medicinal solution will cause pain at the injection site and cannot be directly used by patients, which is not conducive to clinical emergency use
[0015] Therefore, we need to overcome the existing problems of poor solubility of ibuprofen, high risk of clinical compatibility, and high pH of the final product
