Nasal Decongestant
A Nasal Decongestant (pronounced: nay-zuhl dee-kon-jes-tant) is a type of pharmaceutical drug that is used to relieve nasal congestion in the upper respiratory tract. The active ingredient in a nasal decongestant typically works by constricting the blood vessels in the nose.
Etymology
The term "Nasal Decongestant" is derived from the Latin words 'nasus' meaning 'nose' and 'decongestare' meaning 'to clear out'. It was first used in the medical field in the early 20th century.
Types of Nasal Decongestants
There are two main types of nasal decongestants: topical and oral.
- Topical nasal decongestants are applied directly to the nasal passages and provide quick relief of nasal and sinus congestion. Examples include oxymetazoline and phenylephrine.
- Oral nasal decongestants are taken by mouth and provide longer-lasting relief of nasal and sinus congestion. Examples include pseudoephedrine and phenylephrine.
