SODIUM CARBOXYMETHYL CELLULOSE
Sodium Carboxymethyl Cellulose, commonly abbreviated as SCMC or CMC, is a derivative of cellulose, a naturally occurring polymer found in plant cell walls. It is synthesized through the modification of cellulose by introducing carboxymethyl groups onto its molecular structure. This modification imparts water-solubility and stability properties to SCMC, making it useful in various pharmaceutical and industrial applications.SCMC is primarily used in medicine as a viscosity modifier or thickener in ophthalmic solutions, eye drops, and artificial tears. It helps in lubricating and protecting the surface of the eye in conditions like dry eye syndrome.
Dosage of SCMC varies depending on the formulation and the specific medical condition being treated. It is typically administered as eye drops or incorporated into ophthalmic gels.
SCMC is generally well-tolerated, but individuals with known hypersensitivity or allergy to cellulose derivatives should avoid its use.
Special care should be taken when using SCMC-containing products in patients with contact lens use, as some formulations may contain preservatives that can interact with lenses.
Common side effects associated with SCMC include temporary blurred vision or mild eye irritation. These effects are usually mild and transient.
There are no known significant drug interactions with SCMC when used as directed. However, patients should inform their healthcare provider about all medications and supplements they are taking.
