Cinalukast is a potent, selective CysLT1 (LTD4) leukotriene receptor antagonist. It is used in the treatment of asthma, cinalukast selectively antagonizes leukotriene D4 (LTD4) at the cysteinyl leukotriene receptor, CysLT1, in the human airway. Cinalukast inhibits the actions of LTD4 at the CysLT1 receptor, preventing airway edema, smooth muscle contraction, and enhanced secretion of thick, viscous mucus.
