Cellulose and its derivatives play a vital role in the pharmaceutical industry due to their biocompatibility, non-toxicity, and versatile functional properties. They are extensively used as excipients in various dosage forms to modify drug release, enhance stability, and improve patient compliance. Key derivatives include **Carboxymethylcellulose Sodium (CMC-Na/CMC)** , which serves as a binder and viscosity-increasing agent in suspensions and tablets; **Ethylcellulose (EC)** and **Cellulose Acetate (CEC)** , which are employed as insoluble coating materials for controlled-release formulations; **Methylcellulose (MC)** , used as a bulk-forming laxative and ophthalmic lubricant; and **Hydroxypropyl Cellulose (HPC)** , which functions as a binder in tablet granulation and as a film-coating agent. Together, these cellulose ethers enable the design of advanced drug delivery systems, ensuring efficacy, safety, and tailored therapeutic outcomes.
