Oass Uses, Dosage, Side Effects, Food Interaction and all others data.
The higher strength of Oass Sodium USP-NF provides long-lasting relief from dryness by forming a soothing gel after administration of the drops on to the eyes.
In a randomized clinical study of patients with mild or moderate forms of eye dryness, ophthalmic treatment with sodium carboxymethylcellulose resulted in a diminished frequency of symptoms compared to the placebo group . Oass interacts with human corneal epithelial cells to facilitate corneal epithelial wound healing and attenuate eye irritation in a dose-dependent manner . It exhibits protective actions on the ocular surface in various applications; it mediates cytoprotective effects on the ocular surface when applied prior to contact lenses and reduces the incidence of epithelial defects during LASIK .

Uses
Oass Sodium is used as a lubricant to relieve irritation and discomfort due to dryness of the eye or due to exposure to wind or sun.
Oass is also used to associated treatment for these conditions: Dry Eyes, Ocular Irritation
How Oass works
Oass binds to the surface of corneal epithelial cells via its glucopyranose subunits binding to glucose receptors GLUT-1 . The residence time of carboxymethylcellulose bound to corneal cells is approximately 2 hours as indicated by a short-term binding assay . Binding of carboxymethylcellulose to the matrix proteins stimulated corneal epithelial cell attachment, migration, and re-epithelialization of corneal wounds .
