What type of drug is commonly used for management of allergic reactions?

• A. Corticosteroids
• B. Antihistamines
• C. Beta-agonists
• D. Leukotriene inhibitors

Answer: (B)

Antihistamines are commonly used for the management of allergic reactions because they directly counteract the effects of histamine, a chemical that is released during an allergic response. When an allergen is encountered, histamines can trigger various symptoms such as itching, swelling, and mucus production. Antihistamines work by blocking the H1 histamine receptors, thereby alleviating these symptoms.

These medications are often the first line of treatment for conditions like seasonal allergies, hives, and other allergic responses. They can provide quick relief from symptoms and are available in various forms, including tablets, liquid, and nasal sprays.

While corticosteroids, beta-agonists, and leukotriene inhibitors have their respective roles in managing various conditions, they are not primarily indicated for acute allergic reactions. Corticosteroids are typically used for more severe inflammation and autoimmune conditions. Beta-agonists are mainly used for respiratory conditions such as asthma, and leukotriene inhibitors focus on leukotriene pathways for inflammatory conditions, but do not target histamine-related symptoms directly. Thus, antihistamines stand out as the most effective and commonly utilized option for managing allergic reactions.
