Clinical monograph: carmellose
Carmellose, also known as carboxymethyl cellulose (CMC), is a water-soluble polysaccharide derived from cellulose. It is commonly used as a thickening agent, emulsifier, and stabilizer in various pharmaceutical formulations, as well as in food products. Carmellose aids in the formation of gels and enhances the viscosity of solutions, making it useful in both topical and oral dosage forms.
Indications
- Dry eye syndrome
- Ocular lubrication
- Gastroesophageal reflux disease (GERD)
- Topical applications (as a lubricant or protectant)
Dosage
Children: Refer to specific formulation guidelines for recommended dosages, as doses vary widely depending on the formulation and intended use.
Adults: Refer to specific formulation guidelines for recommended dosages, as doses vary widely depending on the formulation and intended use.
Mechanism of action
Carmellose works by increasing the viscosity of solutions and forming a gel-like consistency when mixed with water. This property allows it to act as a lubricant and protectant, particularly in formulations designed for ocular or gastrointestinal use. The water-binding capacity of carmellose helps to retain moisture in tissues, which can be beneficial in treating dryness.
Pharmacodynamics
The pharmacodynamic properties of carmellose are primarily related to its ability to modify the physical properties of solutions and suspensions. It does not exert specific pharmacological effects but rather enhances the bioavailability and stability of active ingredients in pharmaceutical formulations. Its hydrophilic nature allows it to hold water and improve the consistency of products, thus facilitating drug delivery and absorption.
Pharmacokinetics
Carmellose is not absorbed systemically when administered orally, as it is primarily used as an excipient. It passes through the gastrointestinal tract without significant metabolism. The elimination half-life is not applicable, as it does not enter systemic circulation. Its effects are localized to the site of application or ingestion, where it acts as a bulking agent or thickener.
Adverse effects
- Gastrointestinal discomfort
- Bloating
- Diarrhea
Precautions
- Use with caution in patients with gastrointestinal disorders
- Monitor for hypersensitivity reactions
Pregnancy
Carmellose is generally considered safe during pregnancy, but it is advisable to consult a healthcare provider before use.
Breast-feeding
Carmellose is considered safe for use during breastfeeding, but it is recommended to seek advice from a healthcare professional.
Storage
Store in a cool, dry place away from direct sunlight.

Clinical monograph: Carmellosesodium
BNF-referencedCarmellose sodium is a high molecular weight polymer used primarily as a lubricant in ocular formulations. It is a derivative of cellulose and acts to relieve symptoms associated with dry eye conditions, including keratoconjunctivitis sicca. The compound forms a protective film on the surface of the eye, thereby enhancing comfort and stability of the tear film.
Indications
- Dry eye conditions
- Keratoconjunctivitis sicca
- Unstable tear film
Dosage
Children: Apply 3–4 times a day or when required to the eye.
Adults: Apply 3–4 times a day or when required to the eye.
Mechanism of action
Carmellose sodium acts as a viscosity-increasing agent, providing lubrication and hydration. It works by creating a gel-like consistency that mimics natural tears, thus improving moisture retention on the ocular surface. This action alleviates dryness and irritation in the eyes.
Pharmacodynamics
Carmellose sodium exhibits mucomimetic properties, which means it has the ability to mimic natural mucus in the eye. Its effectiveness in reducing symptoms of dryness is attributed to its ability to increase tear film stability and provide a protective barrier against environmental irritants. It does not have systemic effects as it is used topically.
Pharmacokinetics
Carmellose sodium is administered topically and is not absorbed systemically, making its pharmacokinetics primarily local. The onset of action is rapid, providing immediate relief for dry eye symptoms. The duration of action depends on factors such as the formulation and frequency of administration. Due to its high molecular weight, it remains on the ocular surface for an extended period, ensuring prolonged lubrication.
Adverse effects
- Transient blurred vision
- Eye irritation
- Allergic reactions
Precautions
- Consult a healthcare professional if symptoms persist
- Avoid contact with the tip of the dropper to prevent contamination
Pregnancy
Carmellose sodium is generally considered safe for use during pregnancy. However, consult a healthcare provider for personalized advice.
Breast-feeding
Carmellose sodium is not known to pose a risk during breastfeeding, but it is advisable to consult a healthcare provider.
Storage
Store at room temperature, away from direct sunlight. Keep out of reach of children.
