Bromfenex PD Chemical Information

brompheniramine maleate - The maleate salt form of brompheniramine, an alkylamine derivative and a histamine antagonist with anticholinergic and sedative properties. Brompheniramine maleate competes with histamine for the H1 receptor. This diminishes the actions of histamine on effector cells and decreases the histamine-mediated symptoms of allergic reaction such as bronchoconstriction, vasodilation, increased capillary permeability and spasmodic contractions of gastrointestinal smooth muscle.

pseudoephedrine hydrochloride - The hydrochloride salt form of pseudoephedrine, a phenethylamine and an diastereomer of ephedrine with sympathomimetic property. Pseudoephedrine hydrochloride displaces norepinephrine from storage vesicles in presynaptic neurones, thereby releasing norepinephrine into the neuronal synapses where it stimulates primarily alpha-adrenergic receptors. It also has weak direct agonist activity at alpha- and beta- adrenergic receptors. Receptor stimulation results in vasoconstriction and decreases nasal and sinus congestion.
