Know a little about “medicine” | Why can montelukast sodium treat asthma?

Winter is here, the weather is getting colder, and Mr. Li's asthma has recurred. The doctor prescribed him Montelukast Sodium Tablets. What kind of medicine is this?

Asthma is an inflammatory disease of the respiratory tract, with symptoms including wheezing, coughing, shortness of breath, chest tightness, etc. One of the inflammatory mediators that causes asthma is leukotriene, which produces strong bronchoconstriction and inflammation after binding to leukotriene receptors, and is one of the "culprits" that cause respiratory inflammation. Montelukast sodium is a leukotriene receptor antagonist that can inhibit the physiological effects of leukotrienes binding to leukotriene receptors, and achieves the effect of controlling asthma through anti-inflammatory treatment. It can be used for the prevention and long-term treatment of asthma, and can also be used to relieve symptoms caused by allergic rhinitis. Asthma patients should take montelukast sodium tablets before bedtime.
