How is asthma typically managed pharmacologically for immediate relief?

The management of asthma for immediate relief is primarily achieved through the use of bronchodilators, specifically short-acting beta-agonists (SABAs), such as albuterol. These medications work by relaxing the muscles around the airways, leading to dilation and allowing for easier airflow during an asthma attack or episode of acute bronchospasm. This rapid action provides prompt relief from symptoms such as wheezing, shortness of breath, and chest tightness.

Short-acting beta agonists are characterized by their quick onset of action, usually within minutes, and are essential for alleviating acute asthma symptoms. They are often referred to as "rescue medications" and are critical for patients' self-management of asthma when experiencing exacerbations.

Long-acting beta agonists (LABAs) are not suitable for immediate relief as they have a slower onset and are intended for maintenance therapy to prevent asthma symptoms over time rather than to address acute episodes. Corticosteroids, while important in managing inflammation associated with asthma and in long-term control, do not provide immediate relief and take longer to exert their effects. Leukotriene receptor antagonists also serve as maintenance therapy and are not effective for acute symptom relief since their action does not take place rapidly enough to alleviate
