A short-acting antihistamine that relieves allergy symptoms such as sneezing, runny nose, and itchy eyes by blocking histamine receptors involved in allergic reactions. It is less sedating than older antihistamines and is often combined with a decongestant to treat nasal congestion alongside allergy symptoms. It requires dosing three times daily due to its relatively brief duration of action.

กลไกการออกฤทธิ์

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.
