Superiority:
Zafirlukast is a potent subtype specific cysteinyl leukotriene type 1 receptor (CysLT1) antagonist; antiasthmatic. The cysteinyl-
leukotrienes (CysLTs), LTC4 and LTD4, are potent mediators of asthma and hypersensitivity. They induce bronchoconstriction,
augment microvascular permeability, and are vasoconstrictors of coronary arteries.
