CMC is an ideal binder due to its excellent binding properties and ability to form strong bonds between particles. It also helps in improving the disintegration and dissolution of tablets, thereby enhancing the bioavailability of the drug.
In addition to its role as a binder, CMC is also used as a disintegrant in tablet formulations. Disintegrants are added to tablets to facilitate their breakup into smaller particles when they come into contact with water. This allows for the rapid release of the drug from the tablet, ensuring its effective absorption in the body. CMC is an effective disintegrant due to its ability to rapidly swell and disintegrate in aqueous media, leading to the quick release of the drug.
Furthermore, CMC is used as a viscosity modifier in liquid formulations such as suspensions, emulsions, and gels. Viscosity modifiers are added to liquid formulations to control their flow properties and ensure uniform distribution of the active ingredients. CMC imparts viscosity to the formulation, preventing sedimentation of particles and improving the stability of the formulation. It also enhances the spreadability and adhesion of topical formulations, making them easier to apply on the skin.
Moreover, CMC is employed as a stabilizer in ophthalmic formulations such as eye drops and ointments. Ophthalmic formulations are delicate and sensitive to microbial contamination and physical instability. Stabilizers are added to these formulations to prevent microbial growth and maintain their physical and chemical stability. CMC acts as a stabilizer by forming a protective barrier around the active ingredients, preventing their degradation and ensuring the safety and efficacy of the formulation.
In conclusion, carboxymethyl cellulose is a valuable polymer with diverse applications in the pharmaceutical industry. Its unique properties make it an ideal choice for various pharmaceutical formulations, including tablets, suspensions, emulsions, gels, and ophthalmic preparations.
