Quick Summary

A bronchodilator is a drug that relaxes the muscles in the bronchial tubes, widening the air passages to the lungs. This action helps to relieve symptoms associated with conditions like bronchitis, which is the inflammation of the bronchial tree. Bronchodilators can be used to ease chest congestion and coughing caused by mucus production. While acute bronchitis is often short-lived and may be treated symptomatically with bronchodilators, chronic bronchitis involves long-term damage to the bronchial tubes, and bronchodilators are part of its symptomatic management.12
