Levocetirizine, the (R) enantiomer of cetirizine, is a potent and selective antagonist of peripheral H1-receptors. Montelukast, the cysteinyl leukotrienes (LTC4, LTD4, LTE4) are potent inflammatory eicosanoids released from various cells including mast cells and eosinophils which bind to cysteinyl leukotriene (CysLT) receptors found in the human airway (including airway smooth muscle cells and airway macrophages) and on pro-inflammatory cells (including eosinophils and certain myeloid stem cells).
