D Fylin 400mg Tablet is used to prevent and treat symptoms of asthma and chronic obstructive pulmonary disease (COPD). Asthma is a chronic (long-term) respiratory condition in which airways narrow, swell, and produce extra mucus, leading to difficulty in breathing. COPD is a group of lung diseases with emphysema (shortness of breath) and chronic bronchitis (inflammation of the lining of bronchial tubes).
D Fylin 400mg Tablet contains Doxofylline, which acts by inhibiting phosphodiesterase 4 (PD-4), thereby relaxing the bronchial smooth muscle of the lung's airways, making it easier for asthma and COPD patients to breathe easily.
