Mechanism of Action

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. Onset: Oral: 15-30 minutes. Duration: As immediate-release tablet: 4-6 hr.
