A
decongestant is a broad class of
medications used to relieve
nasal congestion. Generally, they work by reducing swelling
of the mucous membranes in the nasal passages. The effects
are not limited to the nose and these medicines can increase
hypertension (blood pressure). These are normally paired
with antihistamines to lessen this effect, but they don't
always even each other out. These agents are usually
administered topically (by the intranasal route) or orally.
Examples of oral decongestants include pseudoephedrine and
phenylephrine; for a full list of Wikipedia articles see
