What is the class of albuterol?

Explanation:
Albuterol is a sympathomimetic agent that directly acts as a beta-2 adrenergic receptor agonist. By stimulating these receptors on airway smooth muscle, it activates the cellular pathway that increases cAMP, causing the muscle to relax and the airways to dilate. This makes it a rapid-acting bronchodilator used for relief of bronchospasm in asthma and COPD. It’s not an anticholinergic (those block acetylcholine to relax airways), not a beta-blocker (those would block beta receptors and can worsen bronchospasm), and while bronchodilation is a form of widening, it isn’t classified as a general vasodilator.
