Short-acting beta agonists (SABAs) are used to treat asthma, chronic obstructive pulmonary disease (COPD), and exercise-induced bronchospasm. They work by relaxing the muscles around your airways, making it easier to breathe. SABAs most commonly come as inhalers and nebulizer solutions. Examples include albuterol (Ventolin HFA, ProAir RespiClick) and levalbuterol (Xopenex HFA). You can discuss with your healthcare team which option might be right for you.
