Mast cell stabilizers are the name given to a group of medicines that prevent the release of histamine and other powerful chemical mediators from mast cells. Mast cells are a type of white blood cell that are part of our immune system and play a key role in our body's response to antigens (a toxic or foreign substance that is perceived as a threat by our body and which induces an immune response).
Mast cells are involved in allergic rhinitis, allergic conjunctivitis, anaphylaxis, asthma, autoimmune diseases, eczema, itch, and reproductive disorders. The mast cell stabilizers cromolyn and nedocromil work by blocking a calcium channel that is essential for mast cell degranulation (the release of chemical mediator-containing secretory granules which occurs after exposure to a specific antigen).
Mast cell stabilizers may be used to prevent asthma and symptoms of seasonal or chronic allergic rhinitis.

Cromolyn
Cromolyn is a medication used to treat asthma and allergic rhinitis. It works by preventing the release of certain chemicals in the body that cause inflammation and allergic reactions. Cromolyn is available as an inhaler for asthma and as a nasal spray for allergic rhinitis. It is generally well-tolerated and can be used in both adults and children. However, it is not a rescue medication and should be used regularly to prevent symptoms rather than to treat acute attacks.
OLOPATADINE HCL is a medication used to treat symptoms of allergic conjunctivitis, such as itching, redness, and watering of the eyes. It belongs to a class of drugs called antihistamines and works by blocking the effects of histamine, a substance in the body that causes allergic symptoms. OLOPATADINE HCL is available in the form of eye drops and is typically used twice a day or as directed by a healthcare professional. It provides relief from eye allergies and helps improve overall eye comfort.
