Duolin 3 Respules is used to treat the symptoms of chronic obstructive pulmonary disease (COPD), like difficulty in breathing, coughing, and wheezing. It contains a combination of ipratropium and levosalbutamol as active ingredients. It works by decreasing the narrowing of the smooth muscles of the airways.
