bronchodilator

A bronchodilator is a medication that helps open up the airways in the lungs, making it easier to breathe. It works by relaxing the muscles around the bronchi—the tubes that carry air in and out of the lungs. This is especially helpful for people with conditions like asthma or chronic obstructive pulmonary disease (COPD), where airway narrowing causes difficulty breathing. Bronchodilators can be inhaled as a quick-relief for sudden symptoms or taken regularly to prevent asthma attacks. They provide prompt relief and improve airflow, making breathing more comfortable.
