Short-acting beta agonist / corticosteroid combinations are used to treat asthma, chronic obstructive pulmonary disease (COPD), and exercise-induced bronchospasm. They work by combining a beta agonist, which helps to relax the muscles around your airways, with a corticosteroid, which reduces inflammation in your airways. These medications are available in inhaler form. An example is albuterol / budesonide (Airsupra).
