Abstract

Sodium cefuroxime is a second-generation cephalosporin widely used at 10mg/mL for endophthalmitis prophylaxis after cataract surgery. Sodium cefuroxime solution is usually conditioned in pre-filled syringes then frozen for storage. In the present study, 0.2% sodium hyaluronate gel, natural extracellular polymer used in wound healing, was compared to conventional saline solution (0.9% sodium chloride) as drug delivery systems for cefuroxime loading in pre-filled syringes. Therefore, the temperature (4 and 25 degrees C) and time of storage (up to 21 days) varied in order to appreciate both cefuroxime and vehicle stability. Furthermore, the kinetics of drug release from both hyaluronate gel and saline solution were compared since in vitro sets of dialysis experiments. Results indicated that cefuroxime loaded in either saline solution or hyaluronate hydrogel was found stable in pre-filled syringes stored at 4 degrees C for 21 days, whereas cefuroxime degradations products appeared from the 2nd day of storage at 25 degrees C. Both drug delivery systems were found bioequivalent, although statistically slower cefuroxime dialysis was evidenced by using sodium hyaluronate vehicle. Noteworthy, cefuroxime concentration in drug delivery sy...Continue Reading
