Which type of medication is typically used for rapid relief of acute asthma attacks?

The use of short-acting beta-agonists (SABAs) is the standard treatment for providing rapid relief during acute asthma attacks. This class of medications works by quickly relaxing the bronchial smooth muscles, leading to dilatation of the airways. This allows for improved airflow and relief from symptoms such as wheezing, shortness of breath, and chest tightness that occur during an asthma attack.

SABAs typically have a quick onset of action, often within minutes, and their effects can last for a few hours, making them ideal for emergency situations where immediate relief is necessary. They are commonly administered via inhalers or nebulizers, which allows for direct delivery to the lungs where they are needed most.

In contrast, long-acting beta-agonists (LABAs) are designed for maintenance therapy and are not suitable for the fast relief of acute symptoms, while inhaled corticosteroids provide anti-inflammatory effects and are more suited for long-term control rather than immediate relief. Leukotriene modifiers also serve a different purpose, focusing on reducing inflammation and bronchoconstriction over a longer period, thus not ideal for acute situations.
