What are beta agonists commonly used for?

Beta agonists are primarily used for treating asthma and other respiratory conditions due to their ability to relax the smooth muscles of the airway, leading to bronchodilation. This mechanism is crucial in alleviating symptoms such as wheezing, shortness of breath, and chest tightness that patients with asthma or chronic obstructive pulmonary disease (COPD) often experience. They mimick the action of adrenaline, stimulating beta-adrenergic receptors in the lungs, which is particularly effective during an asthma attack or when experiencing respiratory distress.

The use of beta agonists is specifically designed to target respiratory issues, making this option the most relevant in the context of the question. For example, medications like albuterol are commonly prescribed beta agonists that provide quick relief from acute asthma symptoms.
