Warnings
There is limited information regarding Warnings of Nedocromil in the drug label.
Adverse Reactions
Clinical Trials Experience
- The most frequently reported adverse experience was headache (~40%).
- Ocular burning, irritation and stinging, unpleasant taste, and nasal congestion have been reported to occur in 10 – 30% of patients. Other events occurring between 1 – 10% included asthma, conjunctivitis, eye redness, photophobia, and rhinitis.
- Some of these events were similar to the underlying ocular disease being studied.
Postmarketing Experience
There is limited information regarding Postmarketing Experience of Nedocromil in the drug label.
Drug Interactions
There is limited information regarding Drug Interactions of Nedocromil in the drug label.
Use in Specific Populations
Pregnancy
- Reproduction studies performed in mice, rats and rabbits using a subcutaneous dose of 100 mg/kg/day (more than 1600 times the maximum human daily ocular dose on a mg/kg basis) revealed no evidence of teratogenicity or harm to the fetus due to nedocromil sodium. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, ALOCRIL® ophthalmic solution should be used during pregnancy only if clearly needed.
- Australian Drug Evaluation Committee (ADEC) Pregnancy Category
There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Nedocromil in women who are pregnant.
Labor and Delivery
There is no FDA guidance on use of Nedocromil during labor and delivery.
Nursing Mothers
- After intravenous administration to lactating rats, nedocromil was excreted in milk. It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when ALOCRIL® ophthalmic solution is administered to a nursing woman.
Pediatric Use
- Safety and effectiveness in children below the age of 3 years have not been established.
Geriatic Use
- No overall differences in safety or effectiveness have been observed between elderly and younger patients.
Gender
There is no FDA guidance on the use of Nedocromil with respect to specific gender populations.
Race
There is no FDA guidance on the use of Nedocromil with respect to specific racial populations.
Renal Impairment
There is no FDA guidance on the use of Nedocromil in patients with renal impairment.
Hepatic Impairment
There is no FDA guidance on the use of Nedocromil in patients with hepatic impairment.
Females of Reproductive Potential and Males
There is no FDA guidance on the use of Nedocromil in women of reproductive potentials and males.

Mechanism of Action
- Nedocromil sodium is a mast cell stabilizer. Nedocromil sodium inhibits the release of mediators from cells involved in hypersensitivity reactions. Decreased chemotaxis and decreased activation of eosinophils have also been demonstrated.
- In vitro studies with adult human bronchoalveolar cells showed that nedocromil sodium inhibits histamine release from a population of mast cells having been defined as belonging to the mucosal sub type and inhibits beta-glucuronidase release from macrophages.
Structure
- ALOCRIL® (nedocromil sodium ophthalmic solution) 2% is a clear, yellow, sterile solution for topical ophthalmic use.
- Nedocromil sodium is represented by the following structural formula:
Pharmacodynamics
There is limited information regarding Pharmacodynamics of Nedocromil in the drug label.
Pharmacokinetics
- Nedocromil sodium exhibits low systemic absorption. When administered as a 2% ophthalmic solution in adult human volunteers, less than 4% of the total dose was systemically absorbed following multiple dosing. Absorption is mainly through the nasolacrimal duct rather than through the conjunctiva. It is not metabolized and is eliminated primarily unchanged in urine (70%) and feces (30%).
Nonclinical Toxicology
- A two-year inhalation carcinogenicity study of nedocromil sodium at a dose of 24 mg/kg/day (approximately 400 times the maximum recommended human daily ocular dose on a mg/kg basis) in Wistar rats showed no carcinogenic potential.
- Nedocromil sodium showed no mutagenic potential in the Ames Salmonella/microsome plate assay, mitotic gene conversion in Saccharomyces cerevisiae, mouse lymphoma forward mutation and mouse micronucleus assays.
- Reproduction and fertility studies in mice and rats showed no effects on male and female fertility at a subcutaneous dose of 100 mg/kg/day (more than 1600 times the maximum recommended human daily ocular dose).
Clinical Studies
There is limited information regarding Clinical Studies of Nedocromil in the drug label.

Patient Counseling Information
- Patients should be advised to follow the patient instructions listed on the Information for Patients sheet.
- Users of contact lenses should refrain from wearing lenses while exhibiting the signs and symptoms of allergic conjunctivitis.
- Patients should be instructed to avoid allowing the tip of the dispensing container to contact the eye, surrounding structures, fingers, or any other surface in order to avoid contamination of the solution by common bacteria known to cause ocular infections. Serious damage to the eye and subsequent loss of vision may result from using contaminated solutions.
Precautions with Alcohol
- Alcohol-Nedocromil interaction has not been established. Talk to your doctor about the effects of taking alcohol with this medication.
