Treatment of atrophic rhinitis can be either medical or surgical. Medical measures include: Nasal irrigation using normal saline [4] Nasal irrigation and removal of crusts using alkaline nasal solutions. 25% glucose in glycerine can be applied to the nasal mucosa to inhibit the growth of proteolytic organisms which produce foul smell.
It is best to take oral antihistamine medication before exposure, especially for seasonal allergic rhinitis. In the case of nasal antihistamines like azelastine antihistamine nasal spray, relief from symptoms is experienced within 15 minutes allowing for a more immediate 'as-needed' approach to dosage. There is not enough evidence of ...
Prolonged use of these types of sprays can damage the delicate mucous membranes in the nose. This causes increased inflammation, an effect known as rhinitis medicamentosa or the rebound effect. Decongestant nasal sprays are advised for short-term use only, preferably 5 to 7 days at maximum. Some doctors advise to use them 3 days at maximum.
Among second-generation antihistamines, cetirizine is more likely than fexofenadine and loratadine to cause drowsiness. [7] Use in pregnancy appears safe, but use during breastfeeding is not recommended. [8] The medication works by blocking histamine H 1 receptors, mostly outside the brain. [6] Cetirizine can be used for paediatric patients.
The nasal spray prevents the glands in the nose from producing large amounts of fluid. [5] [6] It is used to treat rhinorrhea (runny nose) caused by allergic rhinitis, nonallergic rhinitis, [5] and the common cold. [7] [2] It is used by metered-dose manual pump spray. Onset of action is within an hour. [7]
The smaller arteries are also constricted and this causes the colour of the nasal epithelium to be visibly paler after dosage. Xylometazoline is an imidazole derivative which is designed to mimic the molecular shape of adrenaline. It binds to α 1 and α 2 adrenergic receptors [11] in the nasal mucosa.
Azelastine nasal spray is indicated for the local treatment of the symptoms of seasonal allergic rhinitis and perennial allergic rhinitis, such as rhinorrhea, sneezing and nasal pruritus in people five years of age and older.
Rhinitis medicamentosa (or RM, also known as rebound congestion) is a condition of rebound nasal congestion suspected to be brought on by extended use of topical decongestants (e.g., oxymetazoline, phenylephrine, xylometazoline, and naphazoline nasal sprays) and certain oral medications (e.g., sympathomimetic amines and various 2-imidazolines) that constrict blood vessels in the lining of the ...
