Inhaled beta2-agonists enlarge (dilate) the airways that lead to the lungs (bronchial tubes). This makes it easier to breathe. They are sometimes used in acute bronchitis to help coughing and wheezing.
- In those with no blockage of airflow (no wheezing is present), beta2-agonists did not appear effective.
- In those with blockage of airflow (wheezing is present), there was some improvement in cough.
The possible benefits of using beta2-agonists should be weighed against the possible side effects of shaking, tremor, and nervousness.
