Ambroxol Hydrochloride
What is Ambroxol?
Ambroxol works to thin down and break up phlegm (sputum) and is used to clear congestion in the treatment of respiratory diseases which have thick phlegm or too much phlegm. Ambroxol is also used as a pain reliever for sore throats as it has a local numbing effect.
Ambroxol starts working about 30 minutes after it has been taken. The breakdown of acid mucopolysaccharide fibers makes the sputum thinner and less viscous and therefore more easily removed by coughing. Although sputum volume eventually decreases, its viscosity remains low for as long as treatment is maintained.
All forms of tracheobronchitis, emphysema with bronchitis pneumoconiosis, chronic inflammatory pulmonary conditions, bronchiectasis, bronchitis with bronchospasm asthma. During acute exacerbations of bronchitis it should be given with the appropriate antibiotic.
