Duolin LD Respules are packaged in an easy-to-recognize green and white box, with each box containing 8 strips, each strip having 5 sachets, and each sachet containing a single dose for use with a nebulizer. This medication is particularly effective in managing chronic obstructive pulmonary disease (COPD) and asthma, helping to alleviate symptoms by improving airflow and easing breathing. The active components of this medication, Ipratropium Bromide and Levosalbutamol (also known as Levalbuterol), work together to open the airways. It is important to store these respules in a cool, dry environment, away from direct light and moisture, and keep them out of the reach of children.
