The first choice of medication for asthma attacks is mainly inhaled beta2 agonists, such as albuterol sulfate nebulized inhalation solution, terbutaline nebulized solution, and also glucocorticoids, such as budesonide nebulized solution, nebulized inhalation. In addition, if necessary, intravenous drip glucocorticosteroids, such as dexamethasone, methylprednisolone, prednisone, and drip bronchodilators, such as terbutaline injection, can be used. By dilating the bronchial tubes and relieving the spasm of bronchial smooth muscle, it can relieve the symptoms of wheezing and shortness of breath. Moreover, the anti-allergic and anti-inflammatory treatment with glucocorticoids can reduce the hyper-reactive state of airways.
