Beschreibung
Carbinoxamine is a competitive histamine H
1 receptor antagonist (K
i = 2.3 nM) and first generation antihistamine. It also competes with [
3H]diltiazem, an L-type calcium channel blocker, for binding to the benzothiazepine site on rat cardiomyocytes (K
i = 1.08 nM). Carbinoxamine decreases negative inotropic activity in isolated guinea pig left atria by 76% (EC
50 = 250 nM) and negative chronotropic activity in guinea pig spontaneously beating isolated right atria (EC
50s = 250 and 480 nM, respectively) by 48% compared with control. Formulations containing carbinoxamine have been used in the treatment of allergic rhinitis.

Definition
ChEBI: The maleic acid salt of carbinoxamine. An ethanolamine-type antihistamine, used for treating hay fever, as well as mild cases of Parkinson's disease.
Allgemeine Beschreibung
Carbinoxamine is availableas a bitter bimaleate salt, (d, l)-2-[p-chloro- -[2-(dimethylamino)ethoxy]benzyl]pyridine bimaleate (Clistin), which isa white crystalline powder that is very soluble in water andfreely soluble in alcohol and in chloroform. The pH of a 1%solution is between 4.6 and 5.1.
Carbinoxamine is a potent antihistaminic and is availableas the racemic mixture. It differs structurally from chlorpheniramineonly in having an oxygen atom separate theasymmetric carbon atom from the aminoethyl side chain. Themore active levo isomer of carbinoxamine has the (S) absoluteconfiguration and can be superimposed on the moreactive dextro isomer (S configuration) of chlorpheniramine.
