🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by competitively blocking histamine H1 receptors on effector cells in the gastrointestinal tract, blood vessels, and respiratory tract. By binding to these receptors, it prevents histamine from exerting its effects, thereby reducing allergic symptoms such as vasodilation, increased vascular permeability, itching, and bronchoconstriction. Additionally, because it crosses the blood-brain barrier, it causes central nervous system depression, which accounts for its sedative effects.
