Dexchlorpheniramine (trade namePolaramine) is anantihistamine withanticholinergic properties used to treatallergic conditions such ashay fever orurticaria.[1][2] It is the pharmacologically activedextrorotatory isomer ofchlorpheniramine.

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

Pharmacology

[edit]

Dexchlorpheniramine is anantihistamine, or anantagonist of thehistamineH1 receptor. A study found that dexchlorpheniramine had a Ki value of 20 to 30 μM for themuscarinic acetylcholine receptors using rat brain tissue.[4]
