(gamma-(4-Chlorophenyl)-pyridine-2-propyl)(dimethyl)ammonium hydrogen (Z)-maleate

개요Dexchlorpheniramine 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.

용도Dexchlorpheniramine 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.

일반 설명Dexchlorpheniramine(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.
