AI Technical Summary

Problems solved by technology

[0007] Most of these drugs on the market use ambroxol as the active ingredient, and some use dextromethorphan hydrobromide as the main ingredient, but they cannot relieve cough and expectorant at the same time

The disintegration time of ordinary tablets of ambroxol hydrochloride on the market is relatively long, and children and the elderly have difficulty swallowing. It is inconvenient for patients to take it, and the compliance is poor, which affects the therapeutic effect of ambroxol hydrochloride. The performance of the injection is unstable during storage. The increase of related substances will have a certain impact on the quality and safety of the drug; and in the process of medication, because the low pH will cause discomfort to the human body, the use of stabilizers will increase the production process and increase the production cost.
