Relying on years of experience in granule coating technology, the company has mastered the technologies of coating taste masking, complexation (inclusion) taste masking and taste bud passivation taste masking. In 2019, it began to successfully apply coating technology to taste improvement and established a relatively complete Taste rating system. Based on the taste score of the compound itself and combined with the drug delivery characteristics, a more reasonable taste masking and flavoring agent adjustment plan is customized. After studying different plans, the taste masking or taste adjustment effect is evaluated through an integrated scoring system, combined with the in vitro release characteristics. Confirm the best taste masking solution and flavoring ratio. Different taste adjustment technologies including taste-masking coating can be carried out. Some products have the characteristics of instant dissolution in the mouth, no gritty feeling, and can be swallowed directly without water. Currently, the company's products under development include rivaroxaban fine granules, montelukast fine granules, etc.; the declared varieties include loxoprofen sodium fine granules, etc.
