Bronchodilators are medications that help open the airways in the lungs, making it easier to breathe. They are commonly used to treat conditions like asthma and chronic obstructive pulmonary disease (COPD). By relaxing the muscles around the airways, bronchodilators reduce symptoms such as wheezing, coughing, and shortness of breath. There are two main types of bronchodilators: short-acting and long-acting. Short-acting bronchodilators provide quick relief during asthma attacks, while long-acting ones are used for ongoing control of symptoms. These medications can be delivered through inhalers or nebulizers, allowing for effective treatment directly in the lungs.
