Question

_______ is classified as non-sedative anti-histamine.

• A. \( \text{Diphenhydramine} \)
• B. \( \text{Promethazine} \)
• C. \( \text{Fexofenadine} \)
• D. \( \text{Pheniramine} \)

Hint:

Remember that "second-generation" antihistamines generally have a lower tendency to cause drowsiness. Fexofenadine is a common example.

Answer 1

The Correct Option is C

Fexofenadine is a second-generation antihistamine that is known for causing less sedation compared to first-generation antihistamines like diphenhydramine, promethazine, and pheniramine. This reduced sedation is due to its lower penetration across the blood-brain barrier.
