Leukotriene Receptor Antagonists

Leukotriene is a group of active compounds obtained from arachidonic acid which function as regulators of allergic and inflammatory reactions. The release of leukotrienes causes airway constrictions, an increase in mucus production, swelling and inflammation in the lungs. This is what usually presents itself as wheezing. Leukotriene Receptor Antagonists (LTRAs) are a group of oral medication which are non-steroidal and come in the form of tablets. They stop the effect of cysteinyl leukotrienes which trigger chemical mediators of asthma. LTRAs are the best known drugs to manage asthma treatment and prevent acute asthma attacks.

Below are listed some of the common drugs in the Leukotriene Receptor Antagonists class.

Leukotriene Receptor Antagonists Uses

When used for a short period of time, Leukotriene receptor antagonists moderate the symptoms of asthma. In addition, LTRAs treat allergic rhinitis, which occurs when the immune system overreacts and retaliates to a harmless protein in the system. This results in the production of inflammatory chemicals which combine with other cells and lead to inflammation. Below you will find a list of uses for LTRAs.

  • Allergic rhinitis
  • Asthma
