About Duolin Forte Inhaler

Duolin Forte Inhaler belongs to the class of medications called bronchodilators used to treat or prevent symptoms of chronic obstructive pulmonary disease (COPD), such as shortness of breath, coughing, and wheezing (whistling sound while breathing). COPD is a lung disorder that includes emphysema (breathing problems caused by a damaged air sac) and chronic bronchitis (inflammation and narrowing of the lining of airways or bronchial tubes).

Duolin Forte Inhaler contains Ipratropium and Levosalbutamol. Duolin Forte Inhaler works by relaxing muscles and widening the airways of the lungs. Thereby, it allows to breathe easily and provides relief from the symptoms of COPD such as coughing, wheezing, and shortness of breath.
