Description

Montelukast is a leukotriene receptor antagonist (LTRA) used for the maintenance treatment of asthma and to relieve symptoms of seasonal allergies. It is usually administered orally. It decreases severity and frequency of acute asthma attacks. The Mont in Montelukast stands for Montreal, the place where the drug was developed.

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.

Indications

  • Asthma
  • Aspirin-exacerbated respiratory disease (AERD)
  • Exercise induced bronchospasm

Montelukast is used as add up therapy with   corticosteroids which has better efficacy than single therapy.
