Cromolyn Sodium
Cromolyn Sodium is an anti-inflammatory medication commonly used to prevent symptoms of asthma, allergic rhinitis, food allergies, and mastocytosis. It works by inhibiting the release of substances from mast cells, which trigger allergic reactions and inflammation. Unlike other asthma medications, Cromolyn Sodium does not work as a bronchodilator and is not used to relieve acute asthma symptoms; instead, it is used for long-term prevention of allergic reactions and inflammation.
