Pseudoephedrine is a decongestant as well as a bronchodilator for the upper respiratory tract, which gives symptomatic relief of nasal congestion. Pseudoephedrine is both an α-and β-adrenergic receptor agonist. It causes vasoconstriction via direct stimulation of α-adrenergic receptors of the respiratory mucosa. It also directly stimulates β-adrenergic receptors causing bronchial relaxation, increased heart rate and contractility. Like ephedrine, pseudoephedrine releasing norepinephrine from its storage sites, an indirect effect. This is its main and direct mechanism of action. The displaced noradrenaline is released into the neuronal synapse where it is free to activate the postsynaptic adrenergic receptors. Guaifenesin reduces the viscosity of tenacious sputum and is used as an expectorant. It increases the hydration of respiratory tract, thereby increasing the volume and reducing the viscosity of bronchial secretions. Triprolidine is an antihistamine; it is used for the symptomatic relief of hypersensitivity reactions including rhinitis, conjunctivitis and urticaria.

Concomitant use of Pseudoephedrine, guaiphenasine & triprolidine with sympathomimetic agents such as decongestants, tricyclic antidepressants, appetite suppressants and amphetamine-like psychostimulants or with monoamine oxidase inhibitors which interfere with the catabolism of sympathomimetic amines may occasionally cause a rise in blood pressure. Because of its pseudoephedrine content, Pseudoephedrine, guaiphenasine & triprolidine partially reverse the hypotensive action of drugs which interfere with sympathetic activity including guanethidine, methyldopa, alpha-adrenergic blocking agents.
