Dexchlorpheniramine is the S-enantiomer of chlorpheniramine which is a 1st generation anti-histamine. Dexchlorpheniramine has more pharmacological activity than the R and so is more potent than the racemic mixture.

In allergic reactions, an allergen binds to IgE antibodies on mast cells and basophils. Once this occurs IgE receptors crosslink with each other triggering a series of events that eventually leads to cell-degranulation and the release of histamine (and other chemical mediators) from the mast cell or basophil. 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. Dexchlorpheniramine, is a histamine H1 antagonist of the alkylamine class. It competes with histamine for the normal H1-receptor sites on effector cells of the gastrointestinal tract, blood vessels and respiratory tract. It provides effective, temporary relief of sneezing, watery and itchy eyes, and runny nose due to hay fever and other upper respiratory allergies.

Uses

Dexchlorpheniramine maleate is a first generation antihistamine used to treat allergic and vasomotor rhinitis, allergic conjunctivitis, and mild urticaria and angioedema.

Dexchlorpheniramine can be used in the treatment of perennial and seasonal allergic rhinitis, vasomotor rhiniti, allergic conjunctivitis due to inhalant allergens and foods, mild uncomplicated allergic skin manifestations of urticaria and angioedema, amelioration of allergic reactions to blood or plasma, and dermographism.

Iafed is also used to associated treatment for these conditions: Allergic Rhinitis (AR), Allergies, Angioedema, Common Cold, Dermographism, Seasonal Allergic Conjunctivitis, Urticaria, Vasomotor Rhinitis

How Iafed works

Competes with histamine for H1-receptor sites on effector cells in the gastrointestinal tract, blood vessels, and respiratory tract. Dexchlorpheniramine is the predominant active isomer of chlorpheniramine and is approximately twice as active as the racemic compound.
