Short-acting beta-agonists (SABAs) are commonly used to relieve acute asthma symptoms due to their rapid onset of action. These medications work by stimulating beta-2 adrenergic receptors in the bronchial smooth muscle, leading to bronchodilation — the widening of the airways in the lungs. This effect allows for quicker relief from symptoms such as wheezing, shortness of breath, and chest tightness during an asthma attack.

SABAs, such as albuterol, are designed to be taken on an as-needed basis, providing prompt relief within minutes, making them ideal for acute situations. Their fast-acting nature is particularly critical in managing sudden asthma exacerbations, allowing individuals to regain control of their breathing quickly.

Other types of medications, like corticosteroids and long-acting beta-agonists (LABAs), serve different purposes. Corticosteroids are effective for long-term control and prevention of asthma symptoms but do not address acute symptoms immediately. LABAs, while useful for maintaining control over asthma and preventing nighttime symptoms, are not intended for quick relief and are generally used in conjunction with inhaled corticosteroids in a regular treatment plan. Antihistamines do not primarily target asthma symptoms and are used instead for allergic reactions
