98% Montelukast Sodium 151767-02-1

White or almost white, hygroscopic powder.Montelukast was launched as Singulair in Mexico and Finland for the management of mild to moderate asthma inadequately controlled by inhaled corticosteroids and short-acting beta2-agonists. Montelukast can be obtained by an seven-step synthesis from 3-[2(E)-(7-chloroquinolin-2-yl)vinyl] benzaldehyde. Montelukast is a potent, selective and orally active antagonist of the CysLT1 (formerly called LTD4) Montelukast has been studied extensively in plac
Montelukast sodium is an organic sodium salt. It contains a montelukast(1-).|Montelukast is an orally available leukotriene receptor antagonist which is widely used for the prophylaxis and chronic treatment of asthma and has been linked to rare cases of clinically apparent liver injury.|Montelukast Sodium is the orally bioavailable monosodium salt of montelukast, a selective cysteinyl leukotriene receptor antagonist with anti-inflammatory and bronchodilating activities. Montelukast selectively and competitively blocks the cysteinyl leukotriene 1 (CysLT1) receptor, preventing binding of the inflammatory mediator leukotriene D4 (LTD4). Inhibition of LTD4 activity results in inhibition of leukotriene-mediated inflammatory events including: migration of eosinophils and neutrophils; adhesion of leukocytes to vascular endothelium, monocyte and neutrophil aggregation; increased airway edema; increased capillary permeability; and bronchoconstriction. The CysLT1 receptor is found in a number of tissues including spleen, lung, placenta, small intestine, and nasal mucosa, and in a variety of cell types including monocyte/macrophages, mast cells, eosinophils, CD34-positive hemopoietic progenitor cells, neutrophils and endothelial cells.
