Hazard Information | Back Directory | [Description]
Brompheniramine is a first generation antihistamine of the propylamine class. It antagonizes histamine H1 receptors (Ki = 6.06 nM) and also inhibits the reuptake of serotonin and norepinephrine.1,2 | [Chemical Properties]
White Solid | [Originator]
Dimetane,Robins,US,1957 | [Uses]
Antihistaminic;H1 Antagonist | [Uses]
This drug is only available in combination with other
medications: Bromfed, Dimetane, Dimetapp, Drixomed, Histatab, Nasahist.
The only difference between this agent and chlorpheniramine is the substitution
of a bromine for a chlorine atom in brompheniramine. | [Definition]
ChEBI: The maleic acid salt of brompheniramine. A histamine H1 receptor antagonist, it is used for the symptomatic relief of allergic conditions, including rhinitis and conjunctivitis. | [Manufacturing Process]
Initially, 4-bromobenzyl-cyanide is reacted with sodium amide and 2-
chloropyridine to give bromophenyl-pyridyl acetonitrile. This is then reacted
with sodium amide then dimethyl amino ethyl chloride to give 4-bromophenyldimethylaminoethyl-
pyridyl acetonitrile. This intermediate is then hydrolyzed
and decarboxylated to bromphenirame using 80% H2SO4 at 140°-150°C for
24 hours. The brompheniramine maleate may be made by reaction with
maleic acid in ethanol followed by recrystallization from pentanol. | [Brand name]
Dimetane (Wyeth). | [Therapeutic Function]
Antihistaminic | [General Description]
Brompheniraminemaleate, (+)2-[p-bromo-α-[2-(dimethylamino)ethyl]benzyl]pyridine bimaleate (Dimetane), differs fromchlorpheniramine by the substitution of a bromine atom forthe chlorine atom. Its actions and uses are like those of chlorpheniramine.It has a half-life of 25 hours, which is almosttwice that of chlorpheniramine. | [Side effects]
The side effects of this
medication are similar to other classes of sedative antihistamines. Some medications
include parabens. Patients sensitive to parabens may develop a sensitivity
reaction. | [storage]
Store at -20°C |
