Problems solved by technology

[0003] However, the limited solubility of ibuprofen in water has slowed the development of its liquid formulations
At present, there are studies to combine ibuprofen with some basic amino acids (such as arginine) to make salts to increase its solubility, but after the salts are made, they need to be refined and then processed, which will significantly increase the preparation cost and cycle, and it is easy to introduce uncertain impurities in the process, increasing side effects
