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[edit]

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]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
