The two most effective western medications for asthma are bronchodilators and glucocorticoids. When treating asthma in the maintenance period, one chewable tablet of montelukast sodium can be taken at bedtime. Montelukast sodium chewable tablet is a leukotriene inhibitor, which can effectively slow down the bronchospasm at night, thus reducing the asthma attack, and is a very good drug for asthma prevention, and is the only bronchodilator that can be used alone. In addition, the more commonly used bronchodilators for the treatment of asthma are terbutaline sulfate and salbutamol, two drugs that can generally be taken as nebulized inhalation treatment. Glucocorticoids can reduce the inflammatory response of the airways and are very effective in treating asthma in combination with bronchodilators. Glucocorticoids alone can also be inhaled during the maintenance phase to prevent asthma attacks, such as budesonide.
