Cellulose is commonly used as an excipient in the pharmaceutical industry. Pharmaceutical excipients, also known as pharmaceutical auxiliaries, are chemical substances used in drug formulation alongside the active pharmaceutical ingredients. These excipients are generally inactive ingredients that enhance the stability, solubility, and processability of pharmaceutical products. They also play a critical role in influencing the absorption, distribution, metabolism, and elimination (ADME) processes of the drugs with which they are co-administered^[1].
