Which of the following medications is NOT typically considered a controller medication?

Inhaled short-acting beta-2 agonists are categorized primarily as rescue medications rather than controller medications. These medications provide immediate relief from acute asthma symptoms by quickly relaxing the muscles around the airways, thus allowing for improved airflow during an asthma attack or exacerbation. They are designed for quick relief and are typically used on an as-needed basis rather than daily, which is characteristic of controller medications.

In contrast, other options such as aerosolized cromolyn, oral leukotriene antagonists, and inhaled corticosteroids are utilized for long-term management of asthma. These medications help to control inflammation, reduce airway reactivity, and prevent the occurrence of asthma symptoms when taken regularly.

Understanding the distinction between these types of medications is crucial for effective asthma management, as controller medications are meant to maintain asthma control over time, while rescue medications address acute situations.
