Which class of medication is commonly used for acute asthma attacks?

Short-acting beta agonists (SABAs) are the primary medications used for the rapid relief of acute asthma attacks. These medications work by stimulating beta-2 adrenergic receptors in the airway smooth muscle, leading to bronchodilation. This quick onset of action, typically within minutes, allows for immediate relief of symptoms such as wheezing, coughing, and shortness of breath during an asthma exacerbation.

SABAs, such as albuterol, are designed for on-demand use, providing fast-acting relief when asthma symptoms occur. Their effectiveness in resolving acute airflow obstruction makes them the gold standard for treating acute asthma episodes. In contrast, other classes of medications, such as long-acting beta agonists or leukotriene modifiers, are not suited for urgent relief as they are intended for maintenance therapy and have a slower onset of action.
