A bronchodilator is a type of medication that helps open the airways in the lungs. It is commonly used to treat conditions like asthma and chronic obstructive pulmonary disease (COPD). By relaxing the muscles around the airways, bronchodilators make it easier for individuals to breathe. There are two main types of bronchodilators: short-acting and long-acting. Short-acting bronchodilators provide quick relief from symptoms, while long-acting ones are used for ongoing control of breathing problems. These medications can be delivered through inhalers or nebulizers, allowing for effective treatment directly to the lungs.
