What is the primary treatment for acute exacerbation of asthma?

The primary treatment for an acute exacerbation of asthma is the use of short-acting beta agonists (SABAs). These medications are specifically designed to provide rapid relief from bronchospasm by relaxing the muscles around the airways. They act quickly, typically within minutes, making them ideal for immediate management of asthma symptoms.

SABAs, such as albuterol, are essential during an acute asthma attack as they help to open the airways, allowing for improved airflow and relief of symptoms such as wheezing, shortness of breath, and chest tightness. Their role in acute management is crucial as they offer fast and effective bronchodilation.

In contrast, long-acting beta agonists are generally not used for acute exacerbations because they take longer to onset and are better suited for chronic management in conjunction with inhaled corticosteroids. Anticholinergic agents can have a role in asthma management but are not the primary treatment during an acute exacerbation. Corticosteroids are important for reducing inflammation in the longer term for exacerbations but are not as immediate in effect as SABAs. Overall, SABAs are the go-to agents for quick relief during an asthma attack.
