The use of short-acting beta-agonists (SABAs) is the standard approach for quick relief of asthma symptoms. These medications work by binding to beta-2 adrenergic receptors in the airways, leading to the relaxation of bronchial smooth muscles. This results in rapid bronchodilation, allowing for almost immediate relief from acute asthma symptoms such as wheezing, shortness of breath, and chest tightness. SABAs are intended for use during an asthma attack or before exercise to prevent exercise-induced bronchospasm, making them essential components of an asthma management plan for immediate symptom control.

In contrast, long-acting beta-agonists (LABAs) are designed for ongoing management and control of asthma symptoms but do not provide the rapid relief needed during acute episodes. Inhaled corticosteroids serve as a maintenance therapy to reduce airway inflammation over time but do not offer immediate symptom relief. Leukotriene modifiers work by blocking the action of leukotrienes, which contribute to inflammation, but again are not intended for rapid relief during an asthma attack. Therefore, the primary role of SABAs sets them apart as the go-to choice for quick relief in asthma management.
