CLINICAL PHARMACOLOGY

Pseudoephedrine hydrochloride is an (alpha)-adrenergic receptor agonist (sympathomimetic) which produces vasoconstriction by stimulating (alpha)-receptors within the mucosa of the respiratory tract. Clinically, pseudoephedrine shrinks swollen mucous membranes, reduces tissue hyperemia, edema, and nasal congestion, and increases nasal airway patency. Guaifenesin promotes lower respiratory tract drainage by thinning bronchial secretions, lubricates irritated respiratory tract membranes through increased mucous flow, and facilitates removal of viscous, inspissated mucus. As a result of these drugs, sinus and bronchial drainage is improved, and dry, nonproductive coughs become more productive and less frequent.
