Albuterol is a short-acting beta-agonist used for which of the following?

• A. Beta-agonist
• B. Antihistamine
• C. Proton pump inhibitor
• D. Diuretic

Answer: (B)

Albuterol is a short-acting beta-adrenergic agonist that works by stimulating beta-2 receptors in the airway smooth muscle. This activation relaxes the smooth muscle, widens the airways, and relieves acute bronchospasm, making it a fast-acting rescue inhaler used in asthma and exercise-induced bronchoconstriction. Because it’s inhaled, the onset is rapid and systemic effects are minimized, though some tachycardia or tremor can occur from beta-receptor stimulation. It’s not an antihistamine (which blocks histamine receptors for allergies), not a proton pump inhibitor (which reduces stomach acid), and not a diuretic (which increases urine output).
