NCIt definition : The sodium salt form of cromolyn, a mast cell stabilizer with anti-inflammatory activity.
Cromolyn sodium probably interferes with the antigen-stimulated calcium transport
across the mast cell membrane, thereby inhibiting mast cell release of histamine,
leukotrienes, and other substances that cause hypersensitivity reactions. Cromolyn
sodium also inhibits eosinophil chemotaxis.;
