DEXBROMPHENIRAMINE is an alkylamine derivative with anticholinergic and sedative properties. It is a histamine H1-receptor antagonist that competes with histamine for the H1-receptor sites on effector cells in the gastrointestinal tract, blood vessels, and respiratory tract. The antagonistic action of this agent blocks the activities of endogenous histamine, which subsequently leads to temporary relief from the negative histamine-mediated symptoms of an allergic reaction such as bronchoconstriction, vasodilation, increased capillary permeability and spasmodic contractions of the gastrointestinal smooth muscle. DEXBROMPHENIRAMINE as a part of combination medicine is used to treat symptoms of the common cold or seasonal allergies, including sneezing, runny or stuffy nose, and itchy, watery eyes.

Xylometazoline, also spelled xylomethazoline, is a medication which is used to improve symptoms of nasal congestion, allergic rhinitis, and sinusitis. Xylometazoline was patented in 1956 and came into medical use in 1959. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system. The drug works by stimulating adrenergic receptors on the lamina propria of blood vessels in the nose. The decongestant effect is due to constriction of large veins in the nose which swell up during the inflammation of any infection or allergy of the nose. The smaller arteries are also constricted and this causes the colour of the nasal epithelium to be visibly paler after dosage. The standard adult solution strength is 0.1% w/v xylometazoline (or 1 mg per 1 mL solution), and the dose for children under 12 is usually 0.05% (0.5 mg/mL).

Triprolidine is a first generation histamine H1 antagonist, which in combination with codeine phosphate and pseudoephedrine hydrochloride is sold under brand name TRIACIN-C. TRIACIN-C is indicated for temporary relief of coughs and upper respiratory symptoms, including nasal congestion, associated with allergy or the common cold.

Brompheniramine is an antihistaminergic medication of the propylamine class. It is a first-generation antihistamine, which is used for the treatment of the symptoms of the common cold and allergic rhinitis, such as runny nose, itchy eyes, watery eyes, and sneezing. 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. Brompheniramine is a histamine H1 antagonist 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. Brompheniramine is metabolised by cytochrome P450s. The halogenated alkylamine antihistamines all exhibit optic isomerism and brompheniramine products contain racemic brompheniramine maleate whereas dexbrompheniramine (Drixoral) is the dextrorotary (right-handed) stereoisomer.

Menthyl lactate is derived from menthol, a compound that comes from peppermint oil, or is made synthetically. Menthol has a natural cooling effect, which makes it useful as a topical analgesic to treat skin irritation, pain, itching or sunburn. Despite its cooling benefits, menthol can be a skin irritant. Like menthol, menthyl lactate is cooling, but it causes less skin irritation than menthol. Menthyl lactate also has a refreshing, minty taste. For this reason, some manufacturers use it as a flavoring ingredient. The compound is recommended for use as a flavor in concentrations of 0.005% to 0.2% and in cosmetic and other external products in concentrations ranging from 0.2% to 2.0%. Menthyl lactate is a known compound available e.g. from Haarmann & Reimer GmbH (Germany) under the name FRESCOLAT, Type ML.
