  • Dextromethorphan, a centrally-acting antitussive agent, depresses the medullary cough center through sigma receptor stimulation, resulting to decreased sensitivity of cough receptors and interruption of cough impulse transmission.Pseudoephedrine is both an α-and β-adrenergic receptor agonist. (medeasy.health)
  • It causes vasoconstriction via direct stimulation of α-adrenergic receptors of the respiratory mucosa. (medeasy.health)
