What are bronchodilators for treating asthma?

ANSWER

Bronchodilators relax the muscle bands that tighten around the airways. This opens the airways, letting more air in and out of your lungs and letting you breathe easier. As the airways open, the mucus moves more freely and can be coughed out more easily.
