Opticrom^TM Allergy 2.0% w/v Eye Drops, Solution

Sodium cromoglicate 2.0% w/v.

For full list of excipients, see section 6.1

Eye Drops, Solution (Eye Drops)

A clear colourless or pale yellow liquid.

For the relief and treatment of seasonal and perennial allergic conjunctivitis.

Topical Ophthalmic administration

One or two drops in each eye four times a day or as indicated by the doctor.

Elderly

No current evidence for alteration of the dose.

The product is contraindicated in patients who have shown hypersensitivity to Sodium cromoglicate, Benzalkonium chloride or Disodium edetate.

Discard any remaining contents four weeks after opening the bottle.

As with other ophthalmic solutions containing Benzalkonium chloride, soft contact lenses should not be worn during treatment period.

Sodium cromoglicate can be used prophylactically. Patients should seek advice before they discontinue use of the product.

None known.

Pregnancy

As with all medication, caution should be exercised especially during the first trimester of pregnancy. Cumulative experience with Sodium cromoglicate suggests that it has no adverse effects on foetal development. It should be used in pregnancy only where there is a clear need.

Lactation

It is not known whether Sodium cromoglicate is excreted in human breast milk but, on the basis of its physicochemical properties, this is considered unlikely. There is no information to suggest the use of Sodium cromoglicate has any undesirable effects on the baby.

As with all eye drops, instillation of these eye drops may cause a transient blurring of vision.

Eye Disorders

Transient stinging and burning may occur after instillation. Other symptoms of local irritation have been reported rarely.

No action other than medical observation should be necessary.

ATC: S01XA

In vitro and in vivo animal studies have shown that Sodium cromoglicate inhibits the degranulation of sensitised mast cells which occurs after exposure to specific antigens. Sodium cromoglicate acts by inhibiting the release of histamine and various membrane derived mediators from the mast cell.

Sodium cromoglicate has demonstrated the activity in vitro to inhibit the degranulation of non-sensitised rat mast cells by phospholipase A and subsequent release of chemical mediators. Sodium cromoglicate did not inhibit the enzymatic activity of released phospholipase A on its specific substrate.

Sodium cromoglicate has no intrinsic vasoconstrictor or antihistamine activity.

Sodium cromoglicate is poorly absorbed. When multiple doses of Sodium cromoglicate ophthalmic solution are instilled into normal rabbit eyes, less than 0.07% of the administered dose of Sodium cromoglicate is absorbed into the systemic circulation (presumably by way of the eye, nasal passages, buccal cavity and gastrointestinal tract). Trace amounts (less than 0.01%) of the Sodium cromoglicate does penetrate into the aqueous humour and clearance from this chamber is virtually complete within 24 hours after treatment is stopped.

In normal volunteers, analysis of drug excretion indicates that approximately 0.03% of Sodium cromoglicate is absorbed following administration to the eye.

None.
