Nebulization is useful for rhinitis, often using inhalation budesonide suspension for nasal nebulization treatment, mainly to play the role of topical hormone anti-inflammatory, reduce mucosal edema, metaplasia, reduce mucosal exudation. The side effects of nebulization are also relatively small, and the patient’s cooperation is still relatively good. Nebulization allows the drug to act on the deep part of the nasal cavity as well as most of the nasal surface, which is still quite effective. The main reason why nebulization is not used much is because it is troublesome to carry a nebulization device, and it takes more than ten minutes to nebulize each time, and the cost of nebulization is also high, so nebulization for rhinitis is replaced by nasal spray hormone therapy for rhinitis. The topical hormones that are commonly used are endosulpride, co-sulpride, reno-cort, etc. The nebulized treatment of rhinitis can also achieve very good results, and nasal spray hormones can be applied at any time very conveniently.
