4 Drug and Medication Information
4.1 Drug Indication

Indicated for the symptomatic relief of burning, irritation and discomfort of the eyes due to dryness or exposure to wind or sun.


5 Pharmacology and Biochemistry
5.1 Pharmacology

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. Carboxymethylcellulose 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.


5.2 MeSH Pharmacological Classification

Laxatives

Agents that produce a soft formed stool, and relax and loosen the bowels, typically used over a protracted period, to relieve CONSTIPATION. (See all compounds classified as Laxatives.)


5.3 Absorption, Distribution and Excretion

5.4 Metabolism/Metabolites

No pharmacokinetic data available.


5.5 Biological Half-Life

No pharmacokinetic data available.


5.6 Mechanism of Action

Carboxymethylcellulose 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.
