General description

Cromolyn sodium is a mast stabilizer, which is used to treat allergies. It is a bischromone and functions as a non-steroidal anti-inflammatory drug. It inhibits the release of histamines from mast cells.


Cromolyn sodium salt has been used to block mast cell activation and to inhibit histamine secretion from rodent peritoneal mast cells. It has also been used to stabilize mast cells.

Biochem/physiol Actions

Cromolyn blocks the release of histamine and other pro-inflammatory mediators from mast cells.
