Patients with acute bronchitis do better with nebulized inhalation because patients with acute bronchitis have cough, sputum, wheezing, etc. Nebulized inhalation has a local anti-inflammatory and reduces airway reactivity, which can relieve the patient’s discomfort. Especially for patients who experience wheezing due to bronchitis, nebulized inhalation can quickly relieve symptoms. The drugs usually chosen for nebulized inhalation include budesonide suspension for inhalation, terbutaline sulfate nebulized solution, and cotrimoxazole solution for inhalation. These drugs have smaller molecular particles, which are easier to be absorbed locally in the airway and can better exert the drug effect. At the same time, nebulized inhalation can promote the discharge of sputum, which has been proved to have a more obvious effect on patients with lower respiratory tract infections.
