Which of the following SABAs are commonly used in the treatment of asthma and COPD?

Albuterol and levalbuterol are short-acting beta-agonists (SABAs) that are commonly utilized in the management of asthma and Chronic Obstructive Pulmonary Disease (COPD). SABAs work by stimulating beta-2 adrenergic receptors in the bronchial smooth muscle, leading to bronchodilation and relief from acute symptoms.

Albuterol is widely used as a rescue inhaler due to its rapid onset of action, providing prompt relief from bronchospasm. Levalbuterol, which is a more selective form of albuterol, may be used in certain patients who experience side effects from albuterol, offering a similar bronchodilatory effect with potentially fewer adverse reactions.

Other options consist of medications that fall into different categories. For instance, formoterol and salmeterol in the first option are long-acting beta-agonists (LABAs), which are not considered SABAs and are instead used for maintenance therapy rather than immediate relief. The third option includes tiotropium and ipratropium, which are anticholinergic medications, and thus do not belong to the SABA category. The final choice, montelukast and zileuton, represents leukotriene receptor antagonists and 5-lip
