bronchodilator
Medication that relaxes and opens airways by reducing bronchial smooth muscle constriction.
Full Definition
A bronchodilator is a pharmacological agent that relieves bronchoconstriction by relaxing smooth muscle in the airways, thereby increasing airflow to the lungs. Common types include beta-2 agonists (such as albuterol), anticholinergics (such as ipratropium), and methylxanthines (such as theophylline). Respiratory therapists administer bronchodilators via various delivery methods including metered-dose inhalers, nebulizers, and dry powder inhalers, and monitor patient response to treatment.
