← Human Body & HealthWhy does inhaled albuterol provide asthma relief more quickly than oral prednisone?
A)Systemic anti-inflammatory cascade occurs rapidly
B)Beta-2 agonist directly relaxes bronchioles✓
C)Immune suppression prevents further inflammation
D)Increased mucus secretion reduces airway resistance
💡 Explanation
Albuterol acts as a beta-2 agonist, directly stimulating receptors on bronchial smooth muscle cells, causing bronchodilation and relieving airway constriction. This is faster because the mechanism directly opposes the bronchospasm, therefore relief is almost immediate, rather than waiting for a systemic anti-inflammatory effect.
