Which medication is commonly used to reduce airway inflammation in croup?

• A. Dexamethasone
• B. Albuterol
• C. Epinephrine
• D. Ibuprofen

Answer: (A)

Croup causes swelling and edema in the upper airway driven by inflammation, so reducing that inflammatory response is the key to improving airway patency. Dexamethasone is a corticosteroid with potent anti-inflammatory effects; it dampens the inflammatory cascade, decreases mucosal edema, and provides a lasting effect after a single dose. This makes it the most effective choice for reducing airway inflammation in croup and is routinely used to shorten symptoms and hospital stays. Albuterol is a bronchodilator that helps mainly if there’s bronchospasm, not the primary problem in typical croup, so it doesn’t address the main issue. Nebulized epinephrine offers rapid, temporary relief by constricting swollen airway vessels but doesn’t reduce inflammation long-term. Ibuprofen targets fever and pain and has no direct effect on airway inflammation.
