Histamine H1 antagonist used in treatment of allergies, rhinitis, and urticaria.

Brompheniramin is an antihistaminergic medication of the propylamine class. It is a first-generation antihistamine. In allergic reactions an allergen interacts with and cross-links surface IgE antibodies on mast cells and basophils. Once the mast cell-antibody-antigen complex is formed, a complex series of events occurs that eventually leads to cell-degranulation and the release of histamine (and other chemical mediators) from the mast cell or basophil. Once released, histamine can react with local or widespread tissues through histamine receptors. Histamine, acting on H1-receptors, produces pruritis, vasodilatation, hypotension, flushing, headache, tachycardia, and bronchoconstriction. Histamine also increases vascular permeability and potentiates pain. Brompheniramin is a histamine H1 antagonist (or more correctly, an inverse histamine agonist) of the alkylamine class. It provides effective, temporary relief of sneezing, watery and itchy eyes, and runny nose due to hay fever and other upper respiratory allergies.

How Brompheniramin works

Brompheniramin is an antagonist of the H1 histamine receptors with moderate antimuscarinic actions, as with other common antihistamines such as diphenhydramine. Due to its anticholindergic effects, brompheniramine may cause drowsiness, sedation, dry mouth, dry throat, blurred vision, and increased heart rate.

Toxicity

Oral, rat: LD₅₀ = 318 mg/kg. Signs of overdose include fast or irregular heartbeat, mental or mood changes, tightness in the chest, and unusual tiredness or weakness.

Food Interaction

Avoid alcohol.
Take with food.

[Moderate] GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents.

Use in combination may result in additive central nervous system depression and
MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol.

Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.
