What is the role of bronchodilators in COPD management?

• A. To increase mucus production
• B. To decrease oxygen saturation
• C. To cure COPD completely
• D. To reduce bronchospasms and improve airflow

Answer: (D)

Bronchodilators relieve airway constriction to improve airflow in COPD. They work by relaxing the smooth muscle lining the airways, which lowers airway resistance and allows greater expiratory flow. That easing of bronchospasm reduces the work of breathing, relieves shortness of breath, and can improve exercise tolerance. They target the reversible component of airflow limitation in COPD and are central to symptom control. They do not cure the disease, do not increase mucus production, and do not lower oxygen saturation; in fact, by widening the airways they can help ventilation and, if needed, support better oxygenation. They are used as short-acting agents for relief and long-acting agents for ongoing maintenance.
