How It Works
Levocetirizine is the active enantiomer of cetirizine and acts as a selective antagonist at the histamine H1 receptor. By blocking histamine binding, it prevents the cascade of allergic symptoms such as vasodilation, increased vascular permeability, and sensory nerve stimulation that lead to sneezing, itching, and rhinorrhea.
