Leukotriene Receptor (cys-LTs) are a family of potent bioactive lipids that act through two structurally divergent G protein-coupled receptors, termed the CysLT1 and CysLT2 receptors. The cysteinyl leukotrienes LTC4, LTD4, and LTE4 are important mediators of human bronchial asthma. Leukotriene Receptor is a member of the superfamily of G protein-coupled receptors and uses a phosphatidylinositol-calcium second messenger system. Activation of CysLT1 by LTD4 results in contraction and proliferation of smooth muscle, oedema, eosinophil migration and damage to the mucus layer in the lung. Leukotriene receptor antagonists, called LTRAs for short, are a class of oral medication that is non-steroidal. They may also be referred to as anti-inflammatory bronchoconstriction preventors. LTRAs work by blocking a chemical reaction that can lead to inflammation in the airways.
