If a patient with asthma uses an albuterol inhaler before exercise, which consequence follows regarding airway resistance?

💡 Explanation

Albuterol is a beta-2 adrenergic receptor agonist, therefore it stimulates smooth muscle relaxation in the bronchioles, reducing airway resistance during exercise-induced bronchospasm, because it mimics epinephrine's bronchodilatory effects. Rather than causing inflammation or increasing mucus, it actively alleviates constriction.
