Which statement describes the role of SABAs in asthma management?

• A. They provide rapid relief and are used for rescue or prevention of exercise-induced bronchospasm.
• B. They are intended for long-term control of airway inflammation.
• C. They are used as the first-line therapy for chronic management with no rescue role.
• D. They cure asthma after a single dose.

Answer: (A)

The main idea is that short-acting beta-2 agonists act as rescue medications, providing rapid relief from bronchoconstriction and also helping to prevent exercise-induced bronchospasm. They work by quickly relaxing airway smooth muscle through beta-2 receptor activation, so relief comes within minutes and lasts for a limited time. Because they don’t reduce airway inflammation, they’re not used for long-term control of asthma. They’re not a cure, and a single dose doesn’t resolve the condition; ongoing management requires controller medications that address inflammation, such as inhaled corticosteroids. If you find yourself needing the rescue inhaler frequently, that signals poor overall control and a need to adjust maintenance therapy. Some patients may use it before exercise, but it’s still for immediate relief rather than chronic management.
