This non-drowsy antihistamine relieves allergy symptoms such as sneezing, runny nose, and itchy eyes by blocking histamine receptors without significantly crossing into the brain. It is used for seasonal allergies and chronic hives and is less likely to cause sedation than older antihistamines.

作用机制

Competitively blocks histamine H1 receptors on effector cells, preventing histamine-mediated vasodilation, increased vascular permeability, bronchoconstriction, and pruritus. First-generation agents also cross the blood-brain barrier, causing sedation.
