🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Dexchlorpheniramine is a first-generation antihistamine that works by competitively blocking histamine H1 receptors in the gastrointestinal tract, blood vessels, and respiratory tract. By blocking these receptors, it prevents histamine from exerting its effects, which include vasodilation, increased vascular permeability, itching, and smooth muscle contraction. Additionally, it has anticholinergic properties that contribute to its side effects such as dry mouth and urinary retention.
