🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by selectively blocking histamine H1 receptors in the central nervous system and peripheral tissues. By blocking these receptors, it prevents histamine from causing allergic symptoms such as itching, sneezing, and runny nose. Additionally, it crosses the blood-brain barrier and binds to H1 receptors in the brain, which leads to sedation and reduction of anxiety. It also has anticholinergic properties that contribute to dry mouth and other effects.
