Which of the following is NOT a SABA agent?

SABAs, or short-acting beta-agonists, are medications commonly used for the quick relief of asthma symptoms due to their fast-acting nature. Levalbuterol, albuterol, and pirbuterol all fall under this category, as they are designed to provide rapid bronchodilation.

Salmeterol, however, is classified as a LABA, or long-acting beta-agonist. LABAs have a duration of action that allows them to be effective for a longer period, typically around 12 hours or more. This makes them more suitable for maintenance treatment of asthma rather than immediate relief, distinguishing them significantly from SABAs.

Understanding the differences between these categories of medications is crucial in the management of asthma and optimizing patient care. Recognizing that salmeterol is not a SABA highlights the importance of knowing which medications are appropriate for acute symptom relief versus long-term management.
