Asthalin Rotacaps is used to treat asthma and chronic obstructive pulmonary disease (COPD). Asthalin Rotacaps helps relieve symptoms like coughing, wheezing and shortness of breath. 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 the bronchial tubes).
