One of the most common manifestations of allergic reactions is inflammation of the mucous membrane of the eyes, the cornea and the skin of the eyelids. It, as a rule, is expressed by reddening of eyes, puffiness, an itch, a burning sensation and the raised or increased a lacrimation, and also a photophobia and deterioration of sight. To stop the inflammatory process in such cases, doctors often prescribe local antiallergic drugs in the form of drops. One of such medicines are eye drops from Lecrolin allergy.
Composition, form of release and effect of the drug Lecrolin
The main component of drops of Lecrolin is sodium cromoglycate. This compound has anti-allergic properties, it helps block the release of inflammatory mediators (histamine, bradykinin, leukotrienes, etc.) from mast cells. This eliminates the phenomenon of inflammation.
Another important ingredient of the drug is polyvinyl alcohol, the properties of which are similar to those of the substance produced by the conjunctival glands. It helps moisturize and soften the surface of the eyes, increase the viscosity of tears and the stability of tear film, enhance the corneal re-epithelialization processes.
Other components of Lecrolin, produced in vials-droppers, are:
- benzalkonium chloride;
- disodium edetate;
- glycerol, water prepared.
In addition, the drug is available in the form of disposable tubes for single use, which do not contain a preservative of benzalkonium chloride. This form is suitable for patients who are hypersensitive to preservatives, as well as for those who use contact lenses.
Lecrolin has practically no systemic effect, because the absorption of sodium cromoglycate through the mucous membrane of the eye is insignificant. The drug is most effective when used prophylactically. The use of this medication can reduce the need for hormonal ophthalmic drugs against allergies.

After instillation of the drug, a brief burning sensation may appear. There is also a violation of clear vision, so immediately after using Lecrolin, you can not drive a car or work with machinery. When using drops containing benzalkonium chloride, patients with contact
