Montelukast Sodium Tablets can be used to relieve cough symptoms, but it is not a cough medicine per se. It is mainly a regulator of leukotriene receptors and can be used clinically to relieve coughing and sneezing symptoms due to allergic rhinitis and bronchial asthma. This drug can reduce the inflammatory reaction of airway mucosa congestion and edema by inhibiting leukotriene receptors, which can make the airway open and can relieve the symptoms of wheezing, shortness of breath and coughing, and for the disease caused by allergic factors, whether in the attack or in remission, you can continue to take it for a period of time to prevent the recurrence of cough.
