How does vasoconstriction help congestion?
Vasoconstriction reduces nasal congestion by preventing fluid from draining from blood vessels into the tissues lining the nasal passages.
Are decongestants Vasoconstrictors?
Nasal decongestants are vasoconstrictors that belong to the pharmacologic class sympathomimetic amines. They exert their primary action by activating alpha-adrenergic receptors on blood vessels of the nasal mucosa. This results in vasoconstriction, which decreases blood flow through the nasal mucosa and shrinks tissue.
