Mast cell stabilizers are medications used to prevent or treat certain allergic disorders. They block mast cell degranulation, stabilizing the cell and thereby preventing the release of histamine and related mediators. One suspected pharmacodynamic mechanism is the blocking of IgE-regulated calcium channels. Without intracellular calcium, the histamine vesicles cannot fuse to the cell membrane and degranulate.

As inhalers they are used to treat asthma, as nasal sprays to treat hay fever (allergic rhinitis) and as eye drops for allergic conjunctivitis. Finally, in oral form, they are used to treat the rare condition of mastocytosis.

Examples

Mast cell stabilizer medications include:

• cromoglicic acid (cromolyn/cromoglycate)
• ketotifen
• lodoxamide
• nedocromil
• pemirolast
• olopatadine
• pemirolast
• lodoxamide

Research

The following substances are studied on their potential mast cell stabilizing effects, but the current results are inconclusive:

• vitamin D
• quercetin

Sodium cromoglycate (cromolyn sodium) has now been available in an intranasal format OTC for almost 10 years Nedocromil is much more potent Other ophthalmic mast cell stabilizers include cromolyn sodium, ketotifen, and pemirolast, and topical antihistamines such as olopatadine also demonstrate mast-cell stabilizing effects. Cromolyn sodium is also used as an oral preparation for the treatment of mastocytosis and has been used off-label in the management of food allergy
