Which medications are typically used to treat bronchospasm?

Beta agonists are the primary class of medications used to treat bronchospasm, particularly in conditions such as asthma and chronic obstructive pulmonary disease (COPD). These medications work by stimulating beta-adrenergic receptors in the lungs, leading to relaxation of the bronchial smooth muscle and dilation of the airways. This action helps alleviate the symptoms associated with bronchospasm, such as wheezing, coughing, and shortness of breath. Common examples of beta agonists include albuterol and salmeterol.

Other medication classes mentioned, such as antihistamines, antidepressants, and aspirin, do not have a direct role in treating bronchospasm. Antihistamines primarily target allergic reactions and histamine-related symptoms, while antidepressants are used for mood disorders and have no effect on airway constriction. Aspirin, an anti-inflammatory and analgesic, does not address bronchospasms directly either, although in some cases, it may influence respiratory issues related to allergies or inflammation. Therefore, beta agonists are the appropriate choice for counteracting bronchospasm effectively.
