About Montelukast:
- It is an oral medication approved to be prescribed daily for long-term use as a “preventer” or “controller” of asthma attacks in adults and children at least 2 years old.
- Montelukast is also used to prevent bronchospasm (breathing difficulties)during exercise in adults and children 6 years of age and older.
- It is also used to help control the symptoms of allergies such as sneezing, stuffy, runny, and itchy nose.
- Developed by Merck and Co. (an American multinational pharmaceutical company), Montelukast was approved by the U.S. Food and Drug Administration (FDA) in 1998 and marketed under the brand name ‘Singulair’.
- It helps improve asthma symptoms by blocking substances in the body called leukotrienes that cause inflammation and swelling.
- In 2020, the U.S. FDA added a ‘black box warning’ to montelukast, and the Medicines and Healthcare Products Regulatory Agency, U.K., issued a health warning saying the drug could cause serious neuropsychiatric adverse effects.

Asthma is a major noncommunicable disease (NCD), affecting both children and adults, and is the most common chronic disease among children.
