Answer Description

The statement is false. Beta-agonist medications, such as albuterol, are commonly used during asthma attacks because they cause bronchodilation, not constriction. They work by binding to beta-2 adrenergic receptors in the bronchial smooth muscle, leading to muscle relaxation and widening of the airways. This action helps to relieve symptoms of an asthma attack, such as wheezing and shortness of breath. Constriction of the bronchial smooth muscle is the problem during an asthma attack, not the desired effect of treatment.
