Which of the following classifies as a short-acting reliever medication for asthma?

The classification of a short-acting reliever medication for asthma is correctly identified as a short-acting beta2 agonist. These medications are designed to provide rapid relief from acute asthma symptoms by relaxing the muscles surrounding the airways, which facilitates easier breathing during an asthma attack or exacerbation. They work quickly, typically within minutes, making them essential for immediate use in response to asthma symptoms.

Short-acting beta2 agonists, such as albuterol, are often the first-line treatment used in rescue inhalers for patients experiencing sudden asthma symptoms. This rapid onset and effectiveness is a key characteristic that distinguishes them from other medication classes that may be used for the long-term management of asthma but do not provide immediate relief.

In contrast, leukotriene receptor antagonists act as maintenance therapy to block leukotrienes, substances in the body that can cause inflammation and bronchoconstriction, but they are not intended for immediate symptom relief. Mast cell stabilizers work by preventing the release of inflammatory mediators but also do not provide immediate relief and are more commonly used for long-term control. Long-acting beta agonists are utilized for the maintenance treatment of asthma due to their prolonged duration of action, but they should never be used as a standalone rescue medication due
