Which class of drugs is primarily used to control symptoms of rhinitis?

• A. Antibiotics
• B. Antihistamines
• C. Antipyretics
• D. Decongestants

Answer: (B)

Antihistamines are specifically designed to block the action of histamine, a chemical released during allergic reactions that can cause symptoms such as sneezing, itching, and runny nose. By inhibiting histamine, antihistamines effectively alleviate the symptoms associated with rhinitis, which may be caused by allergies or other irritants.

In contrast, antibiotics are used to treat bacterial infections, not symptoms of allergic rhinitis. Antipyretics are medications aimed at reducing fever, and they do not directly address rhinitis symptoms. Decongestants may help relieve nasal congestion but do not target the broader symptoms of rhinitis as effectively as antihistamines do, particularly for allergic reactions. Therefore, antihistamines are the most appropriate choice for controlling the symptoms associated with rhinitis.
