Nebulizer therapy is the most commonly used treatment for respiratory infectious diseases and can be used both in the hospital and at home. Nebulized therapy is dispensed mainly with glucocorticoids, and the drugs include budesonide suspension. If an asthmatic patient has a significant exacerbation of airway responsiveness with a croupy sound in the throat and dyspnea on movement, a beta agonist can be added to an inhaled glucocorticoid, such as budesonide. Commonly used are salbutamol suspension and terbutaline suspension, both of which can effectively relieve bronchospasm smooth muscle and rapidly improve the clinical manifestations of chest tightness, shortness of breath and asthma. Therefore, the choice of nebulization at home is to use glucocorticoids alone or in combination with beta agonists to relieve the condition as soon as possible and improve a series of symptoms of respiratory chest tightness and shortness of breath.
