Triprolidine hydrochloride is a potent competitive histamine H1-receptor antagonist with antimuscarinic and mild sedative properties.

Pseudoephedrine is both an alpha-and beta-adrenergic receptor agonist. It causes vasoconstriction via direct stimulation of alpha-adrenergic receptors of the respiratory mucosa. It also directly stimulates beta-adrenergic receptors causing bronchial relaxation, increased heart rate and contractility.

Guaifenesin increases the volume and reduce the viscosity of tenacious sputum and is used as an expectorant for productive cough.
