SYSTANE® Lubricant Eye Drops

SYSTANE® Lubricant Eye Drops

The #1 Doctor Recommended artificial tear1, SYSTANE® Lubricant Eye has been clinically proven2 to reduce both the measurable signs and patient-described symptoms of dry eye. Providing immediate, long-lasting moisture and protection, it's no wonder that SYSTANE® is preferred nearly 2 to 13 over other dry eye treatments on the market. When patients seek relief, recommend SYSTANE® Lubricant Eye Drops as their first-line dry eye treatment.


Biphasic Mechanism of Action

Most dry eye drops simply add volume to the tear film, providing only short-term relief. As soon as the moisture dissipates, the symptoms return. SYSTANE® Lubricant Eye Drops actually prolong tear film break-up time (TFBUT) with a unique biphasic mechanism of action (MOA)4. As a result, SYSTANE® offers long-lasting symptom relief and an enhanced environment for ocular surface repair.

SYSTANE® eye drops contain a unique gelling and lubricating polymer system formulated to adjust to each patient's individual tear film pH. This ensures optimum performance and provides enhanced relief for a patient's specific physiological needs.

Mechanism of Action

The polymerizing protection of SYSTANE® is achieved through the interaction of soothing demulcents (polyethylene glycol 400 and propylene glycol), HP-Guar and the patient's own natural tears.

When the HP-Guar in SYSTANE® eye drops combines with certain elements found in the tears, a chemical reaction occurs. HP-Guar binds to the hydrophobic (water-repelling) corneal surface, forming a surface-anchored network with a gel-like consistency. By cross-linking with borate ions, HP-Guar helps keep the demulcent system (polyethylene glycol / propylene glycol) on the surface of the eye longer, providing long-lasting relief from the symptoms of dry eye.

At the same time, SYSTANE® also helps create an ocular shield, allowing for epithelial repair in a healthy and protected environment. The protection of SYSTANE® Lubricant Eye Drops provides long lasting relief and sustained comfort.
