Long-acting bronchodilators are medications used to help open the airways in the lungs, making it easier to breathe. They are commonly prescribed for conditions like asthma and chronic obstructive pulmonary disease (COPD). These medications work by relaxing the muscles around the airways, providing relief for up to 24 hours with just one dose. These bronchodilators are typically taken once or twice a day, depending on the specific medication. They are different from short-acting bronchodilators, which provide quick relief but last for a shorter time. Long-acting bronchodilators are often part of a comprehensive treatment plan that may include other medications and lifestyle changes.
