Western medicines used to treat allergic rhinitis include chlorpheniramine, cetirizine, oxymetazoline, budesonide, ipratropium bromide, and sodium cromoglycate. Allergic rhinitis belongs to a kind of non-infectious inflammatory disease of nasal mucosa. Currently, the western drugs used in the clinical treatment of allergic rhinitis include antihistamines, such as chlorpheniramine, cetirizine, brompheniramine, loratadine, and levocabastine hydrochloride. There are also nasal decongestants such as hydroxymetazoline, naphazoline, furosemide nasal drops, ephedrine, and anticholinergic drugs such as ipratropium bromide. There are also nasal glucocorticosteroids such as budesonide, fluticasone propionate, mometasone furoate, and mast cell membrane stabilizers such as sodium cromoglycate and nedocromil. The above drugs should be used in a standardized manner under the guidance of a specialist to avoid adverse drug reactions and allergic symptoms.
