Dexchlorpheniramine Maleate Chemical Properties,Uses,Production

Description

Dexchlorpheniramine Maleate is the maleate salt form of dexchlorpheniramine, an alkylamine, and first-generation histamine antagonist with anti-allergic activity. Dexchlorpheniramine maleate competitively blocks H1 receptors, thereby preventing the actions of histamine on bronchial smooth muscle, capillaries and gastrointestinal (GI) smooth muscle. This prevents histamine-induced bronchoconstriction, vasodilation, increased capillary permeability, and GI smooth muscle spasms.

Chemical Properties

Dexchlorpheniramine maleate is a white, odourless, crystalline powder which in aqueous solution has a pH of between 4 and 5. It is freely soluble in water, soluble in alcohol and in chloroform, but only slightly soluble in benzene or ether.

Originator

Polaramine,Schering,US,1958

Uses

Dexchlorpheniramine is an antihistamine used to relieve symptoms of allergy, hay fever, and the common cold. Polaramine (dexchlorpheniramine maleate) is the dextro-isomer of chlorpheniramine maleate and the S-enantiomer of Chlorpheniramine. It is an antihistamine with anticholinergic properties. S-(+)-Chlorpheniramine maleate salt has been used to study the anticholinergic effect of Achillea millefolium and Portulaca olerace on muscarinic receptors of guinea pig tracheal smooth muscle.

Definition

ChEBI: Dexchlorpheniramine maleate is an organic molecular entity.

Manufacturing Process

Twenty grams of d-phenylsuccinic acid and 28 grams of 3-(2-pyridyl)-3-pchlorophenyl-N,N-dimethylpropylamine are dissolved in 400 ml of absolute ethyl alcohol and allowed to stand at room temperature until crystallization is effected. The crystals are filtered, washed with absolute ethyl alcohol and recrystallized from 300 ml of this solvent in the same manner. The crystals are recrystallized twice from 80% ethyl alcohol using 3.5 ml per gram of compound in the manner described above and pure d-3-(2-pyridyl)-3-pchlorophenyl-N,Ndimethylpropylamine-d-phenylsuccinate is obtained, melting point 145-147°C.
This salt is shaken with 100 ml of diethyl ether and 50 ml of 20% aqueous potassium carbonate; the ether layer is separated, dried over anhydrous potassium carbonate, filtered and the ether is removed in vacuo. The d-3-(2- pyridyl)-3-p-chlorophenyl-N,N-dimethylpropylamine so obtained is a mobile oil.
4.3 grams of the above base and 1.8 grams of maleic acid are dissolved in 20 ml isopropyl acetate and kept at room temperature until crystallization is complete. The crystals are filtered, washed with ethyl acetate and recrystallized from 15 ml of this solvent in the same manner. The crystalline d-3-(2-pyridyl)-3-p-chlorophenyl-N,N-dimethylpropylamine maleate so formed is then filtered off and dried. MP 113-115°C from US Patent 3,030,371.

brand name

Mylaramine (Morton Grove); Polaramine (Schering).

Therapeutic Function

Antihistaminic

General Description

Dexchlorpheniramine(Polaramine) is the dextrorotatory enantiomer of chlorpheniramine.In vitro and in vivo studies of the enantiomers ofchlorpheniramine showed that the antihistaminic activity existspredominantly in the dextro isomer. As mentioned previously,the dextro isomer has the (S) configuration, which issuperimposable on the (S) configuration of the more activelevorotatory enantiomer of carbinoxamine.

Biochem/physiol Actions

H1 histamine receptor antagonist; active isomer.Chlorpheniramine maleate is clinically used as a topical ointment to treat skin disorders such as sunburn, urticaria, angioedema, pruritus and insect bites.

Mode of action

Dexchlorpheniramine, the d-isomer of the racemic compound chlorpheniramine, is two times more active than chlorpheniramine. Dexchlorpheniramine does not prevent the release of histamine, but rather, competes with free histamine for binding at the H1-receptor sites, and competitively antagonizes the effects of histamine on H1- receptors in the GI tract, uterus, large blood vessels, and bronchial muscle. Blockade of H1-receptors also suppresses the formation of oedema, flare, and pruritus that result from histaminic activity. Since dexchlorpheniramine binds to central and peripheral H1-receptors, sedative effects are likely to occur. H1- antagonists are structurally similar to anticholinergic agents and therefore possess the potential to exhibit anticholinergic properties of varying degrees. They also have antipruritic effects. Dexchlorpheniramine has high antihistaminic activity, moderate anticholinergic effects and minimal sedative effects. The medicine does not possess antiemetic properties.
