A 56-year-old woman with COPD presents with shortness of breath but no fever or sputum production. Which pharmacological treatment is most appropriate for immediate symptom relief at this initial contact?

• A. Short-acting beta-2 agonist
• B. Inhaled corticosteroid
• C. Long-acting beta-agonist
• D. Theophylline

Answer: (A)

Immediate relief of COPD symptoms requires rapid bronchodilation, which is achieved by a short-acting beta-2 agonist. This class acts quickly on airway smooth muscle, typically within minutes, to open the airways and relieve breathlessness—ideal for use at the moment symptoms appear. Inhaled corticosteroids, while important for control of inflammation, have a slower onset and are not intended for acute relief. Long-acting beta-agonists provide prolonged bronchodilation but are maintenance therapies, not rescue meds, so they don’t address sudden symptoms. Theophylline is older and has a narrow therapeutic window with more side effects and interactions, making it less suitable for immediate relief. If symptoms persist despite using the rescue inhaler, seek further assessment.
