Polyethylene Glycol 400 + Propylene Glycol Systane Ultra is an artificial tear whose two demulcents, polyethylene glycol 400 at 0.4 percent and propylene glycol at 0.3 percent, are held on the eye by a hydroxypropyl guar gelling system.
- Artificial tears work and this is a competent one
- Two demulcents holding water on the eye surface
- A guar gelling system keeps it in place longer
- Slower tear film evaporation through the day
- Preservative free single use vials for frequent dosing
Mechanism
The two demulcents raise the viscosity and water holding capacity of the tear film so it evaporates more slowly and the ocular surface stays wetted. Hydroxypropyl guar cross links as the drop meets the slightly higher pH of the eye, forming a soft gel that keeps the demulcents in place; it is an excipient, not an active.
Safetyrisks and cautions, not medical advice
Polyethylene Glycol 400 + Propylene Glycol is a fixed combination product in the blend class. A full adverse effect profile has not been compiled for this entry yet, so nothing here should be read as evidence that it is well tolerated; the absence is missing work rather than a finding. What is documented is what the compound is and what it is used for.
Subjective profileweighing the evidence above
Nothing here to be excited about and nothing to worry about. Artificial tears work, this is a competent one, and the guar gelling system that holds it on the eye is the only thing separating it from a dozen others on the same shelf. Preservative free single use vials are worth the extra cost for anyone reaching for drops more than a few times a day, since preservative toxicity is the main way frequent users make dry eye worse. Dry eye that keeps needing drops has causes worth identifying, and a demulcent treats the symptom indefinitely without touching any of them.
