Problems solved by technology

[0005] There are many processes in this process, and after repeated test verification, it is found that the quality is not good, and because of multiple coatings, the heating time of the tablet core is long, and the contact time with water is long, and the analysis shows that the reason for the instability of olanzapine is Process modification is necessary due to discoloration caused by olanzapine hydrate
