Dexchlorpheniramine (trade name Polaramine) is an antihistamine with anticholinergic properties used to treat allergic conditions such as hay fever or urticaria.[1][2] It is the pharmacologically active dextrorotatory isomer of chlorpheniramine.

It came into medical use in 1959 and was patented in 1962.[3]

Pharmacology

Dexchlorpheniramine is an antihistamine, or an antagonist of the histamine H1 receptor. A study found that dexchlorpheniramine had a Ki value of 20 to 30 μM for the muscarinic acetylcholine receptors using rat brain tissue.[4]
