Long-acting beta agonists (LABAs) are primarily used to treat chronic obstructive pulmonary disease (COPD). But certain medications in this class can also be used for asthma and exercise-induced bronchospasm. LABAs work by relaxing the muscles around your airways, making it easier to breathe. These medications are available as inhalers and nebulizer solutions. Examples include arformoterol (Brovana), formoterol (Perforomist), and salmeterol (Serevent Diskus). You can discuss with your healthcare team which option might be right for you.
