Duolin-3 is a respiratory medication presented in convenient respules, packaged in a distinctive green and white box. Each box contains 320 sachets (8 strips of 5 respules each), designed for administration via a nebulizer. It is specifically used for the management of chronic obstructive pulmonary disease (COPD) and asthma, providing relief by combining the active ingredients Ipratropium Bromide and Levosalbutamol (Levalbuterol). Store respules in a cool, dry area away from direct sunlight and moisture. Ensure they are kept out of the reach of children.
