Cromolyn Disodium Salt Chemical Properties,Uses,Production


Sodium cromoglycate is the sodium salt and common market from of cromoglicic acid, which is a synthetic compound, and as a mast cell stabilizer. It is capable of inhibiting the antigen-induced bronchospasms, and thus being used to treat the asthma and allergic rhinitis. It can also be applied as an ophthalmic solution for the treatment of conjunctivitis and systemic mastocytosis and ulcerative colitis. It is capable of inhibiting the degranulation of mast cells, further preventing the release of histamine and slow-reacting substance of anaphylaxis (SRS-A), the mediators of type I allergic reaction. It is also capable of inhibiting the release of inflammatory leukotrienes and inhibiting calcium influx.

Cromolyn sodium (Intal) is chemically related drugs called chromones that is used for the prophylaxis of mild or moderate asthma. It is administered by inhalation and has very good safety profiles, making them particularly useful in treating children.


ChEBI: An organic sodium salt that is the disodium salt of cromoglycic acid.

General Description

Cromolyn sodium, disodium 1,3-bis(2-carboxychromon-5-yloxy)-2-hydroxypropane (Intal), isa hygroscopic, white, hydrated crystalline powder that is solublein water (1:10). It is tasteless at first but leaves a veryslightly bitter aftertaste. The pK of cromolyn is 2. It is availableas a solution for a nebulizer, an aerosol spray, a nasal solution,an ophthalmic solution, and an oral concentrate.
Nebulized and aerosol cromolyn has been used for prophylacticmanagement of bronchial asthma and prevention ofexercise-induced bronchospasm. Cromolyn nasal solution isused for the prevention and treatment of allergic rhinitis, andoral concentrate is used to treat the histaminic symptomsof mastocytosis (diarrhea, flushing, headaches, vomiting, urticaria,abdominal pain, nausea, and itching). Topical cromolyn(eye drops) is used to treat allergic conjunctivitis andkeratitis. In the treatment of asthma, cromolyn efficacy is manifestedby decreased severity of clinical symptoms, or need for concomitant therapy, or both. Long-term use is justified if thedrug significantly reduces the severity of asthma symptoms;permits a significant reduction in, or elimination of, steroiddosage; or improves management of those who have intolerableside effects to sympathomimetic agents or methylxanthines.For cromolyn to be effective, it must be administered atleast 30 minutes prior to antigen challenge and administered atregular intervals (see dosing information that follows). Wheninhaled, the powder does produce irritation in some patients.Also, overuse of cromolyn can result in tolerance.

Mechanism of action

The precise mechanism or mechanisms whereby cromolyn sodium and nedocromil sodium exert their antiasthmatic activities is unknown. Early work suggested that these agents act by “stabilizing” mast cells, preventing mediator release. However, several other compounds exhibit greater potency for stabilization of mast cells yet possess no clinical efficacy in asthma.This suggests that the therapeutic activity of cromolyn sodium and nedocromil sodium in asthma is related to one or more other pharmacological mechanisms. Postulates include inhibitory effects on irritant receptors, nerves, plasma exudation, and inflammatory cells in general.

Clinical Use

Cromolyn sodium is used almost exclusively for the prophylactic treatment of mild to moderate asthma and should not be used for the control of acute bronchospasm. This agent is effective in about 60 to 70% of children and adolescents with asthma. Unfortunately, there is no reliable means to predict which patients will respond.It is less effective in older patients and in patients with severe asthma. It may take up to 4 to 6 weeks of treatment for cromolyn sodium to be effective in chronic asthma, but it is effective after a single dose in exercise-induced asthma. With respect to clinical efficacy, cromolyn sodium and nedocromil sodium do not differ in a substantial way.

Side effects

Cromolyn sodium is the least toxic of available therapies for asthma. Adverse reactions are rare and generally minor. Those occurring in fewer than 1 in 10,000 patients include transient bronchospasm, cough or wheezing, dryness of throat, laryngeal edema, swollen parotid gland, angioedema, joint swelling and pain, dizziness, dysuria, nausea, headache, nasal congestion, rash, and urticaria.
