Lecrolyn (Sodium Cromoglicate)

Sodium Cromoglicate, the active ingredient in Lecrolyn, is a mast cell stabilizer presented as a topical ophthalmic solution for ocular use. It is indicated for the treatment of allergic conjunctivitis and other ocular allergic conditions, where it works by inhibiting mast cell degranulation and preventing the release of histamine and other inflammatory mediators that cause eye irritation, redness, and itching.

GNH USA supplies Lecrolyn as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, providing reliable sourcing for ophthalmic antiallergic agents.

Lecrolyn, a mast cell stabilizer, is used to manage ocular allergic disorders by preventing mast cell mediator release.

- Allergic conjunctivitis: reduces eye redness, itching and tearing associated with seasonal and perennial allergens. - Vernal keratoconjunctivitis: helps control inflammation and itching in this chronic allergic eye disease. - Seasonal ocular allergy: alleviates symptoms of eye irritation during pollen seasons.

Adverse ocular reactions to Lecrolyn are generally mild and transient, but rare serious events have been reported.

Common Side Effects: - Burning sensation: mild stinging upon instillation. - Eye irritation: temporary gritty feeling. - Blurred vision: transient visual haziness after dosing.

Serious or Rare Side Effects: - Allergic contact dermatitis: localized swelling and rash. - Corneal ulceration: persistent pain and visual disturbance. - Anaphylaxis: systemic allergic reaction, though extremely uncommon.

Before using Lecrolyn, consider the following precautions to ensure safe and effective therapy.

- Pregnancy: consult a healthcare professional before use. - Breastfeeding: discuss potential risks with a physician. - Contact lens wearers: remove lenses prior to instillation and wait before reinserting. - Ocular infection: avoid use if active eye infection is present. - Hypersensitivity: discontinue if signs of allergic reaction occur. - Store at room temperature: keep in original container, protect from light and moisture.

Lecrolyn may interact with other ophthalmic agents; awareness of these interactions helps optimize treatment.

Major Interactions (Avoid): - Concurrent use of ocular anesthetics: may increase ocular irritation. - Combination with other mast cell stabilizers: provides no added benefit and may increase exposure.

Moderate Interactions (Monitor Closely): - Co‑administration with antihistamine eye drops: may reduce efficacy of either product. - Use with topical corticosteroids: monitor for additive anti‑inflammatory effects. - Preservative‑containing contact lens solutions: may heighten irritation.
