Ambroxol Hydrochloride Injection is indicated for the following conditions, mainly acute and chronic respiratory diseases with abnormal sputum secretion and poor sputum excretion function, such as acute exacerbation of chronic bronchitis, wheezing bronchitis, bronchiectasis, bronchial asthma and pneumonia, all of which can be nebulized with Ambroxol Injection.
