What is the primary use of Short acting beta2 agonists (SABA)?

Short-acting beta2 agonists (SABAs) are primarily used to relieve acute reversible airflow obstruction, which is a hallmark of conditions like asthma and chronic obstructive pulmonary disease (COPD). These medications work quickly to dilate the airways, providing rapid relief from symptoms such as wheezing, coughing, and shortness of breath.

Their onset of action is typically within minutes, making them an essential tool for managing acute asthma attacks or exacerbations, allowing individuals to breathe more easily in situations where airway constriction occurs.

While they can also play a role in preventing exercise-induced bronchospasm and may sometimes be used in conjunction with other treatments for chronic bronchitis, their primary and most recognized function is as a quick-relief medication during acute episodes. This rapid action and effectiveness in alleviating symptoms underscore why they are considered the go-to option for immediate symptom relief in asthma management.
