How can bronchodilators treat asthma?

ANSWER

These drugs treat asthma by relaxing the muscle bands that tighten around the airways. They open the airways quickly to let more air in and out of the lungs to help you breathe.

Bronchodilators also help clear mucus from the lungs. As the airways open, the mucus moves more freely and can be coughed out more easily. In the short-acting form, bronchodilators relieve or stop asthma symptoms and are very helpful during an asthma attack. The 3 main types of bronchodilators are beta2 agonists, anticholinergics, and theophylline.
