The modified extracted lignin hydrogel was prepared and the Ciprofloxacin drug was used to examine the loading and release capabilities of hydrogel. The hydrogel was characterized by FT-IR, TGA-DTG, and SEM analysis as well as swelling ratio and mechanical test. The outcomes demonstrated that the hydrogel that was made shows high mechanical strength (elongation 442.85%), swelling ratio, effectively contained and released the ciprofloxacin. The developed hydrogel encapsulation effectiveness of CP was seen to rise as the drug concentration increased, reaching around 81.3 ± 4.1% at 500 µg/mL of CP. A release analysis conducted in vitro in phosphate buffer saline (PBS) demonstrated a consistent increase in the cumulative drug release, with the greatest release quantity reaching around 88.2 ± 3.2% after 10 h. As compared to hydrogel containing a lower quantity of drug (0.07 ± 0.06%), the hydrogel with high drug loading efficiency (0.78 ± 0.08%) showed a rapid and greater release rate. The CP-loaded hydrogel exhibits antibacterial activity towards <i>S. aureus</i>, <i>B. subtilis, A. baumannii, P. aeruginosa</i>.
