montelukast
A leukotriene receptor antagonist, Montelukast is used for treating asthma and other allergic symptoms. It works by blocking a substance called leukotriene, which helps to decrease certain asthma and allergy symptoms. Reference standards of Montelukast API,and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below.
