Ambrodil S Syrup is used to treat cough associated with respiratory disorders like asthma and chronic obstructive pulmonary disease (COPD). Asthma is a breathing problem in which airways narrow, swell, and produce extra mucus, leading to difficulty breathing. COPD is a group of lung diseases with emphysema (shortness of breath) and chronic bronchitis (inflammation of the lining of your bronchial tubes). Coughing occurs as a reflex action in the throat when there is mucus or any other foreign irritant in it.
