There are various formulations of nebulized medications for children, the most important of which are currently glucocorticoids, which are hormonal drugs, as well as bronchodilators, phlegmolytic drugs, and normal saline. Glucocorticoids are very important therapeutic drugs for eliminating the inflammation of bronchial mucosa. When bronchodilators are inhaled, the bronchial tubes are dilated, and deep phlegm or bronchospasm causing coughing, shortness of breath, and severe discomfort can be effectively relieved. Direct inhalation of phlegmolytic drugs can dilute the more viscous phlegm in the bronchial tubes and facilitate its discharge. Nebulized inhalation should be used under the guidance of a doctor.
