Explanation:
Detailed explanation-1: -Official answer. Singulair (montelukast) will be in your system for approximately 30.3 hours. The mean plasma half-life of montelukast ranges from 2.7 to 5.5 hours in healthy young adults. This is the time it takes for your body to reduce the plasma levels by half.
Detailed explanation-2: -It works by blocking the effects of leukotrienes, a substance produced by the body in response to certain “triggers” that cause narrowing and swelling of airways in the lungs. It may be taken alone or in addition to other asthma medications. Montelukast usually starts to work within one day.
