🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Cetirizine is a selective antagonist of the histamine H1 receptor. It works by competitively inhibiting the binding of histamine to H1 receptors on effector cells in the gastrointestinal tract, blood vessels, and respiratory tract. This action prevents histamine-induced symptoms such as vasodilation, increased vascular permeability, and sensory nerve stimulation, which are responsible for allergic reactions. Unlike first-generation antihistamines, cetirizine has limited penetration into the central nervous system, resulting in less sedation.
