Bacterial cellulose (BC) is a highly purified form of cellulose that offers several benefits, including an ultrafine fiber network, a high water retention capacity, and simple fabrication into desired forms. There has been a recent uptick in BC’s focus on drug delivery for biomedical applications. Studies on prodrug design, controlled-release methods, and pill coating have all been conducted for BC. This research was done to determine if BC might be employed as a medication carrier in chemical and biological formulations. BC microparticles laden with the medication were produced via grinding. Clordiazepoxide hydrochloride (CDP) was used to test the microparticles’ drug loading and release capabilities. Particle morphologies, drug loading efficiency, loaded drug physical state, and drug release behavior were all assessed for the manufactured microparticles. Amorphous microparticles were formed from BC microparticles. An scanning electron microscope (SEM) study found that the microparticles had a nearly round form with an average diameter of 400–500 μm. Drug loading was greater in the renewed BC microparticles (37.57 ± 0.22%) when the concentration of drugs was held constant at 10%. More than 85% of the medication was delivered for all formulations in the first 30 minutes.
