1. Name Of The Medicinal Product
GelTears.
2. Qualitative And Quantitative Composition
Clear, colourless gel containing 0.2% w/w carbomer 980 Ph.Eur.
3. Pharmaceutical Form
Eye gel.
4. Clinical Particulars
4.1 Therapeutic Indications
Substitution of tear fluid in the management of dry eye conditions, including keratoconjunctivitis sicca and unstable tear film.
4.2 Posology And Method Of Administration
Adults (including the elderly) and children:
One drop to be instilled into the conjunctival fold of each affected eye 3 - 4 times daily or as required, depending on the degree of discomfort.
4.3 Contraindications
Use in patients with a known hypersensitivity to any component of the preparation.
4.4 Special Warnings And Precautions For Use
Blurred vision can occur if too much gel is instilled at one time, or if the gel is used too frequently. This effect can last for up to an hour. Recovery can be aided by blinking vigorously for a few seconds. If this fails, the lower eyelid should be manipulated until the gel returns to the lower fornix and normal vision is restored.
Contact lenses should be removed during treatment with GelTears.
4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction
No significant interactions have been reported.
4.6 Pregnancy And Lactation
Safety for use in pregnancy and lactation has not been established, therefore, Geltears should not be used in these circumstances.
4.7 Effects On Ability To Drive And Use Machines
As with other ophthalmic preparations, transient blurring of vision may occur on instillation. If affected, the patient should be advised not to drive or operate hazardous machinery until normal vision is restored.
4.8 Undesirable Effects
Corneal irritation due to benzalkonium chloride could possibly occur with prolonged use.
4.9 Overdose
Not applicable.
5. Pharmacological Properties
5.1 Pharmacodynamic Properties
GelTears contains Carbomer 980, a hydrophilic, high molecular weight polymer of carboxyvinylic acid. The gel forms a transparent lubricating and moistening film on the surface of the eye. The preparation has a pH similar to that found in the normal tear film and is slightly hypotonic with respect to tears. GelTears relieves the symptoms of irritation linked with dry eye syndromes and protects the cornea against drying out.
The use of vital stains has provided objective evidence that the corneal and conjunctival epithelial lesions associated with dry eye syndromes show improvement on treatment with GelTears. The gel remains on the surface of the eye for longer than low viscosity artificial tears and hence, less frequent application is required.
5.2 Pharmacokinetic Properties
No human pharmacokinetic studies are available, however, absorption or accumulation in ocular tissues is likely to be negligible due to the high molecular weight of the active ingredient.
5.3 Preclinical Safety Data
No adverse safety issues were detected during the development of this formulation. The ingredients are well established in clinical ophthalmology.
