AIRY 10
Generic Name: Montelukast Sodium
Therapeutic Category: Anti-inflammatory
Pharmacological Class: Leukotriene receptor antagonist
Composition: Each film coated tablet contains Montelukast Sodium IP 10 mg

Presentation: Available in the pack size as 10 tablets X 10 strips
Mechanism of Action
Montelukast blocks the action of leukotriene D4 on the cysteinyl leukotriene receptor CysLT1 in the lungs and bronchial tubes by binding to it. This reduces the bronchoconstriction otherwise caused by the leukotriene, and results in less inflammation. Because of its method of operation, it is not useful for the treatment of acute asthma attacks.
