Mast Cell Stabilizers

Produce mast cell stabilization and antiallergic effects that inhibit degranulation of mast cells. [103] Have no direct anti-inflammatory or antihistaminic effects. Effective for prophylaxis. May be used just before exposure to a known allergen (eg, animal, occupational). Begin treatment 1-2 wk before pollen season and continue daily to prevent seasonal allergic rhinitis. Effect is modest compared with that of intranasal corticosteroids. Excellent safety profile and are thought to be safe for use in children and pregnancy.

Cromolyn sodium (Nasalcrom)

Available OTC in the United States. Used daily for seasonal or perennial allergic rhinitis. Significant effect may not be observed for 4-7 d. For patients with isolated and predictable periods of exposure (eg, animal allergy, occupational allergy), administer just before exposure. Generally less effective than nasal corticosteroids. Protective effect lasts 4-8 h, frequent dosing is necessary.
