Cromolyn Sodium

**Semantic type:** Pharmacologic Substance

**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.
