Which of the following medications is commonly used to treat Reactive Airway Disease (RAD)?

Inhalers are commonly used to treat Reactive Airway Disease (RAD), which encompasses conditions like asthma where airway responsiveness and hyperreactivity are key concerns. Inhalers typically deliver bronchodilators or corticosteroids directly into the lungs, providing rapid relief from acute symptoms and reducing inflammation over time.

Bronchodilators, such as beta-agonists (e.g., albuterol), help to relax the smooth muscles around the airways, allowing them to open up and facilitate easier breathing. Corticosteroid inhalers, on the other hand, help to decrease inflammation within the airways and are critical for long-term management of RAD by preventing exacerbations.

Other medications listed, such as antibiotics, antihistamines, and analgesics, do not address the primary physiological issues associated with RAD. Antibiotics are used to treat bacterial infections, antihistamines primarily address allergic reactions, and analgesics are for pain relief. These treatments do not have a direct effect on the bronchospasm and airway inflammation seen in reactive airway conditions, making inhalers the most appropriate and effective choice for managing RAD.
