Used primarily in the prevention and management of asthma and allergic conditions, this compound acts as a mast cell stabilizer, helping to inhibit the release of inflammatory mediators like histamine. It is commonly administered via inhalation for asthma prophylaxis, particularly in patients with mild to moderate persistent asthma. Also found in ophthalmic solutions to relieve symptoms of allergic conjunctivitis, such as itching and redness. Additionally, it may be used orally in the treatment of systemic mast cell disorders, including mastocytosis, where it helps reduce gastrointestinal symptoms caused by mast cell activation. Its preventive action requires regular use, as it is not effective for acute symptom relief.
