AI Technical Summary

Problems solved by technology

Due to the poor water solubility of the active ingredients, the raw materials are usually micronized, but due to electrostatic aggregation, after the micronized raw materials are made into preparations, the dissolution rate will gradually decrease during the long-term stability storage process, and the accelerated investigation will be 3 to 6 months. Dissolution decreased by 10-15%
