Adults can take cisplatin, which is montelukast sodium, a leukotriene receptor antagonist, which is available in three sizes, called montelukast sodium granules, montelukast sodium chewable tablets and montelukast sodium tablets. Montelukast sodium granules are suitable for children over the age of 1 year, montelukast sodium chewable tablets are suitable for children aged 2 to 14 years, and montelukast sodium tablets are suitable for adults aged 15 years and above. These drugs are mainly used to prevent daytime or nighttime asthma symptoms and exercise-induced bronchoconstriction, and are also effective in reducing clinical symptoms in patients with seasonal or perennial allergic rhinitis. Asthma patients should take montelukast sodium at bedtime. Pregnant women usually need to avoid using this drug, and since this drug can be secreted from breast milk, nursing women should also use this drug with caution. In addition, the drug is a prescription drug and should be used under the guidance of a doctor to avoid nausea, vomiting, gastrointestinal disorders, dizziness, physical weakness, itchy skin and other adverse reactions caused by improper use.
