Description
Carboxymethyl Cellulose Sodium Eye Drops are a sterile, isotonic, and preservative-containing ophthalmic solution formulated with Carboxymethyl Cellulose Sodium (CMC Sodium), a water-soluble polymer derived from cellulose. These drops act as a lubricant and artificial tear substitute, providing relief from dry, irritated, or fatigued eyes. They help restore moisture, protect the ocular surface, and improve patient comfort by mimicking natural tears.
Mechanism of Action:
Carboxymethyl Cellulose is a high-viscosity polymer that binds water molecules, forming a protective, lubricating film over the corneal and conjunctival surfaces. This film reduces friction during blinking, enhances tear film stability, and prevents evaporation of natural tears. Its viscoelastic properties provide prolonged moisture retention, aiding in the healing of dry, damaged, or irritated ocular tissues.
Uses:
- Relief of symptoms associated with dry eyes (xerophthalmia)
- Temporary relief from eye irritation due to exposure to wind, sun, or air conditioning
- Post-operative use following ocular surgery to promote comfort and healing
- Supportive therapy in keratoconjunctivitis sicca
- Contact lens-induced dryness (consult eye care professional)
- Minor ocular irritations caused by environmental factors
