Alcon Tears Naturale II Med Lubricating eye col 15ml - treatment of moderate to severe dry eye
Warning: Last items in stock!
Eye drops, solution
Clear, colourless solution
Tears substitute for the symptomatic treatment of moderate to severe dry eye, including keratoconjunctivitis sicca.
Instill 1 or 2 drops into the conjunctival sac of the affected eye(s) as needed, up to once every 1-2 hours or as prescribed by the physician.
Adults, children, and the elderly
These drops may be used by both adults and children.
Hypersensitivity to dextran 70, hypromellose or to any of the excipients.
• If patients experience headaches, eye pain, changes in vision, persistent redness or irritation of the eyes, or if the condition worsens or persists for more than 3 days, they are to discontinue use and consult a doctor.
If more than one topical ophthalmic medicinal product is being used, the medicines must be administered at least 5 minutes apart. Eye ointments should be administered last.
There are no or limited amount of data from the use of TEARS NATURALE in pregnant women. However, the components dextran 70 and hypromellose exert a surface protective effect and are not pharmacologically active. These components are not expected to be absorbed systemically, to demonstrate any systemic toxicity or to have any effect on reproduction or embryofetal development. TEARS NATURALE can be used during pregnancy.
It is unknown whether dextran 70, hypromellose or any of the components are excreted in human milk. Nonetheless, discontinuation of product use during breast-feeding is not considered necessary. TEARS NATURALE can be used during breast-feeding.
TEARS NATURALE has no or negligible influence on the ability to drive or use machines. As with any eye drops, temporary blurred vision or other visual disturbances may affect the ability to drive or use machines. If blurred vision occurs at instillation, the patient must not drive or use machinery until the vision is completely cleared.
a. Summary of the safety profile
The most frequently occurring adverse reaction during clinical trials was vision blurred.
b. Tabulated list of adverse reactions
The following adverse reactions are classified according to the following convention: very common (≥ 1/10), common (≥ 1/100 to <1/10), uncommon (≥1/1,000 to <1/100), rare (≥1/10,000 to <1/1,000), very rare (<1/10,000), or not known (cannot be estimated from the available data). Within each frequency-grouping, adverse reactions are presented in order of decreasing seriousness. The adverse reactions were obtained from clinical trials and post marketing spontaneous reports.

Reporting of side effects
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard
• No case of overdose has been reported.
• An overdoseof TEARS NATURALE can easily be washed out of the eye with lukewarm tap water.
ATC Code S01X A20
TEARS NATURALE is an unpreserved physiological tear product that exerts a physical, not a pharmacologic action, and it contains the ionic components of the human tear: calcium, magnesium, sodium, potassium, zinc, bicarbonate and chloride ions. TEARS NATURALE SINGLE DOSE also contains the DUASORB system, which consists of two water-soluble polymers: Dextran 70 and hypromellose. The system provides a lubricant and emollient effect to the cornea. The surface tension and viscosity of TEARS NATURALE are similar to those of natural tears.
An animal model study demonstrated that a tear solution with physiologic electrolyte composition, including bicarbonate, can provide an environment for the cornea which is conducive to recovery from epithelial damage. This suggests that artificial tears containing bicarbonate may also be of benefit in the treatment of the compromised ocular surface epithelium of dry eye patients. An open-label, non-randomized, parallel group study was conducted in which 14 patients with keratoconjunctivitis sicca received treatment with TEARS NATURALE . This study demonstrated that TEARS NATURALE provided objective improvement in ocular surface desiccation, cell pathology and symptomatic complaints as compared with a control formulation without bicarbonate. Although statistical comparisons were not conducted between or within treatments, results were considered clinically significant.
5.2 Pharmacokinetic properties
The pharmacokinetics of Dextran 70 and hypromellose have not been studied in this product. Due to the high molecular weights of these polymers, penetration into the cornea and conjunctiva is expected to be low.
The preclinical safety of TEARS NATURALE was demonstrated in an exaggerated treatment regimen with 12 applications of the product to rabbits' eyes over a 5.5-hour period. Prior to instillation, the test samples had been opened, stored at room temperature for 10 days, followed by storage at 45° C for 50 hours, in order to increase the pH to approximately 8.8. Under this exaggerated treatment regimen, the product was found to be well tolerated.
