When it stimulates these receptors causes muscles in the airways to relax and open airways for appropriate breathing practice.

In conditions where there is a narrowing of the airways, i.e. conditions named asthma or chronic obstructive pulmonary disease (COPD, like emphysema and chronic bronchitis), it is difficult for air to get in and out of a person’s lungs. Hence, in such cases, the drug works by opening the airways and making it easier for the person to breathe.

The drug form is available in conventional tablets and inhalers. Inhaling the drug allows acting directly in the lungs where it is needed the most.

The inhalers can also be used shortly before exercising or exposure to allergens (things that trigger wheezing, like pet’s fur or pollen) for opening airways and preventing wheezing.
