Which type of drug is used to treat acute allergic reactions?

Anesthetics
Antibiotics
Antihistamines
Corticosteroids

The correct answer is: Antihistamines

Antihistamines are the type of drug used to treat acute allergic reactions. Antihistamines work by blocking the action of histamine, a substance in the body that causes allergic symptoms such as itching, sneezing, and hives. By blocking the effects of histamine, antihistamines help relieve these symptoms and are commonly used to manage allergic reactions. Anesthetics, antibiotics, and corticosteroids are not typically used to treat acute allergic reactions. Anesthetics are used for numbing pain, antibiotics are used to treat bacterial infections, and corticosteroids are used for reducing inflammation in conditions such as asthma or arthritis, but they are not the first-line treatment for acute allergic reactions.
