How are bronchodilators used to treat asthma?

ANSWER

Bronchodilators relieve the symptoms of asthma by relaxing the muscles that can tighten around the airways. This helps to open up the airways.

Short-acting bronchodilator inhalers, often called rescue inhalers, quickly relieve the cough, wheezing, chest tightness, and shortness of breath caused by asthma. But you shouldn't use them every day.

Doctors sometimes prescribe long-acting bronchodilators in combination with inhaled steroids or corticosteroids to control asthma symptoms or when someone has ongoing asthma symptoms despite treatment with a daily inhaled steroid.
