Medications given to dilate the bronchioles include which of the following?

Medications that are specifically used to dilate the bronchioles are known as bronchodilators, which are primarily used in the management of respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). In this context, terbutaline and theophylline are both recognized bronchodilators.

Terbutaline, a beta-2 adrenergic agonist, works by relaxing the muscles in the airways, leading to increased airflow and relief from bronchospasm. Theophylline, a methylxanthine, helps to open up the airways by acting on the smooth muscles and also has anti-inflammatory effects, contributing to improved respiratory function.

This differentiates them from the other medications listed, which do not primarily target bronchodilation. Diazepam and haloperidol are primarily used for anxiety and psychotic disorders, respectively. Promethazine and diphenhydramine are antihistamines, often used for allergies or motion sickness, and do not have bronchodilator effects. Ibuprofen and sulindac are nonsteroidal anti-inflammatory drugs (NSAIDs) recommended for pain relief and inflammation, with no role in bronchodilation.

Therefore, terbutaline and theophylline are the correct
