Which of the following is a bronchodilator used to treat asthma?

• A. Albuterol
• B. Medrol
• C. Maxair
• D. Singulair

Answer: (A)

Bronchodilators open the airways by relaxing the smooth muscle around the bronchi, providing quick relief from asthma symptoms. Albuterol is a rapid-acting beta-2 adrenergic agonist that quickly relaxes those airway muscles, so it’s the go-to choice for immediate relief during an asthma flare. Medrol is a corticosteroid that reduces airway inflammation over time, not immediate bronchodilation, so it isn’t used for quick relief. Singulair is a leukotriene receptor antagonist that helps prevent symptoms with daily use, not a fast-acting bronchodilator. Maxair is another short-acting bronchodilator, but albuterol is the best-known and most widely used option for rapid relief in asthma.
