Anti-allergic rhinitis medications usually include antihistamines, nasal decongestants, anticholinergics, and nasal glucocorticoids. 1. Antihistamines: Antihistamines have anti-allergic effects and can quickly relieve symptoms such as nasal itching, sneezing, nasal hypersecretion, etc., such as: loratadine, levocabastine hydrochloride, cetirizine hydrochloride and so on are commonly used antihistamines in clinical practice. 2. Nasal decongestants: Nasal decongestants are usually used as adjunctive medications to relieve nasal congestion, usually furosemide nasal drops, hydroxymethazoline, seroquel nasal drops and so on. 3. Anticholinergics: anticholinergics have the effect of relaxing bronchial smooth muscle, commonly used isoproterenol bromide. 4. Nasal glucocorticosteroids: nasal glucocorticosteroids have a certain alleviating effect on the inflammatory reaction of the nasal mucosa, and because glucocorticosteroids are absorbed locally, its systemic bioavailability is very low, the effect is fast, and safe, common mometasone furoate, budesonide, fluticasone propionate and so on. When patients with allergic rhinitis should go to the hospital in time, follow the doctor’s instructions to standardize the use of drugs and treatment, do not self-medication.
