• Recent EU Clinical Trials: A Phase II/III Adaptive, Seamless, Prospective, Randomized, Controlled, Parallel, Open Multicenter Study to Assess the Safety and Efficacy of Kék Lukács Ointment Compared to Standard Silver Sulfadiazine (Dermazin?, SSD) Therapy in the Wound Healing of Patients With Partial Thickness (Second-Degree) Burns
• Uses: Indicated as an adjunct for the prevention and treatment of wound sepsis in patients with second- and third-degree burns. Coordination compound. Antibacterial Silver(I) sulfadiazine (AgSD) is popularly used for treating second-degree burn wounds as it acts as an antimicrobial agent and prevents infections. Silver sulfadiazine-impregnated polyurethane (PU) foam, chitosan/chondroitin sulfate films may be used for wound dressing.
• Indications: Silver sulfadiazine (Silvadene, SSD) is a synthetic agent that combines the beneficial properties of silver nitrate and sulfonamides. It acts upon the cell membrane and cell wall. It is used primarily as an adjunct in the prevention and treatment of wound sepsis in patients with second- and third-degree burns and for wound care of chronic ulcers. It is bactericidal against many gram-positive and gram-negative bacteria as well as C. albicans and is reasonably effective against P. aeruginosa and S. aureus. Bacteria susceptible to sulfadiazine but resistant to silver nitrate, as well as those sensitive to silver nitrate but resistant to sulfadiazine, have shown good response to silver sulfadiazine. It does not stain, is unlikely to produce electrolyte imbalance, and does not cause systemic acidosis. Some patients note a stinging sensation on application, and because this compound can be absorbed, systemic sulfonamide reactions similar to those caused by sulfonamides may occur.
• Clinical Use: The silver salt of sulfadiazine applied in a water-misciblecream base has proved to be an effective topical antimicrobialagent, especially against Pseudomonas spp. This is particularlysignificant in burn therapy because pseudomonadsare often responsible for failures in therapy. The salt is onlyslightly soluble and does not penetrate the cell wall butacts on the external cell structure. Studies using radioactivesilver have shown essentially no absorption into body fluids.Sulfadiazine levels in the serum were about 0.5 to2 mg/100 mL.This preparation is reported to be easier to use thanother standard burn treatments, such as application offreshly prepared dilute silver nitrate solutions or mafenideointment.

Green electrochemical synthesis of silver sulfadiazine microcrystals

10.1039/c9ra04504j

Faezeh Zivari Moshfegh, Mahmood Masoudi Khoram, and Davood Nematollahi utilized a quasi-two-compartment cell with a sacrificial silver rod anode and a stainless steel plate cathode. The cell design involved an anode compartment containing aqueous sulfadiazine and sodium nitrate, and a cathode compartment with nitric acid solution, connected through a solvent surface layer. The researchers investigated the effects of various experimental parameters, including applied current density, sodium nitrate concentration, and nitric acid concentration, on the yield and energy consumption of silver sulfadiazine (AgSD) synthesis. The results showed that the yield of AgSD was consistently high (97 ± 2%) across different current densities, while the size of the AgSD crystals could be controlled by adjusting the current density. The study also optimized the concentrations of sodium nitrate and nitric acid to minimize energy consumption. The synthesized AgSD microcrystals were characterized using techniques such as XRD, FE-SEM, and EDS, confirming their purity and morphology.
