Each 5 mL ampule of Cromolyn Sodium Oral Solution (Concentrate) contains 100 mg cromolyn sodium, USP, in purified water. Cromolyn sodium is a hygroscopic, white powder having little odor. It may leave a slightly bitter aftertaste. Cromolyn Sodium Oral Solution (Concentrate) is clear, colorless, and sterile. It is intended for oral use.

Chemically, cromolyn sodium is disodium 5,5’-[(2-hydroxy-trimethylene) dioxy]bis[4-oxo-4H-1-benzopyran-2-carboxylate]. The empirical formula is C23H14Na2O11; the molecular weight is 512.34. Its chemical structure is:

Pharmacologic Category: Mast cell stabilizer

Therapeutic Category: Antiallergic

In vitro and in vivo animal studies have shown that cromolyn sodium inhibits the release of mediators from sensitized mast cells. Cromolyn sodium acts by inhibiting the release of histamine and leukotrienes (SRS-A) from the mast cell.

Cromolyn sodium has no intrinsic vasoconstrictor, antihistamine, or glucocorticoid activity.

Cromolyn sodium is poorly absorbed from the gastrointestinal tract. No more than 1% of an administered dose is absorbed by humans after oral administration, the remainder being excreted in the feces. Very little absorption of cromolyn sodium was seen after oral administration of 500 mg by mouth to each of 12 volunteers. From 0.28 to 0.50% of the administered dose was recovered in the first 24 hours of urinary excretion in 3 subjects. The mean urinary excretion of an administered dose over 24 hours in the remaining 9 subjects was 0.45%.

Four randomized, controlled clinical trials were conducted with Cromolyn Sodium Oral Solution (Concentrate) in patients with either cutaneous or systemic mastocytosis; two of which utilized a placebo-controlled crossover design, one utilized an active-controlled (chlorpheniramine plus cimetidine) crossover design, and one utilized a placebo-controlled parallel group design. Due to the rare nature of this disease, only 36 patients qualified for study entry, of whom 32 were considered evaluable. Consequently, formal statistical analyses were not performed. Clinically significant improvement in gastrointestinal symptoms (diarrhea, abdominal pain) were seen in the majority of patients with some improvement also seen for cutaneous manifestations (urticaria, pruritus, flushing) and cognitive function. The benefit seen with Cromolyn Sodium Oral Solution (Concentrate) 200 mg QID was similar to chlorpheniramine (4 mg QID) plus cimetidine (300 mg QID) for both cutaneous and systemic symptoms of mastocytosis.

Clinical improvement occurred within 2-6 weeks of treatment initiation and persisted for 2-3 weeks after treatment withdrawal. Cromolyn Sodium Oral Solution (Concentrate) did not affect urinary histamine levels or peripheral eosinophilia, although neither of these variables appeared to correlate with disease severity. Positive clinical benefits were also reported for 37 of 51 patients who received Cromolyn Sodium Oral Solution (Concentrate) in United States and foreign humanitarian programs.

Cromolyn Sodium Oral Solution (Concentrate) is indicated in the management of patients with mastocytosis. Use of this product has been associated with improvement in diarrhea, flushing, headaches, vomiting, urticaria, abdominal pain, nausea, and itching in some patients.

Cromolyn Sodium Oral Solution (Concentrate) is contraindicated in those patients who have shown hypersensitivity to cromolyn sodium.

The recommended dosage should be decreased in patients with decreased renal or hepatic function. Severe anaphylactic reactions may occur rarely in association with cromolyn sodium administration.

In view of the biliary and renal routes of excretion of Cromolyn Sodium Oral Solution (Concentrate), consideration should be given to decreasing the dosage of the drug in patients with impaired renal or hepatic function.

Most of the adverse events reported in mastocytosis patients have been transient and could represent symptoms of the disease. The most frequently reported adverse events in mastocytosis patients who have received Cromolyn Sodium Oral Solution (Concentrate) during clinical studies were headache and diarrhea, each of which occurred in 4 of the 87 patients. Pruritus, nausea, and myalgia were each reported in 3 patients and abdominal pain, rash, and irritability in 2 patients each. One report of malaise was also recorded.
