Inhalers are the primary medical treatment for asthma. During acute exacerbations, inhaled short-acting beta-agonists (SABAs), such as albuterol/salbutamol, are considered the primary tool for managing asthma.[1] As their name suggests, these drugs bind to β2 adrenergic receptors and cause the smooth muscles in the bronchi to relax and open.[2][1]
If asthma is classified as “intermittent” or worse, inhaled long-acting beta-agonists (LABAs) and glucocorticoids can be used for more continuous or daily treatment.[3]
