Sodium vitrate is a physiologically active substance widely present in animals and humans. It is distributed in human skin, synovial fluid, umbilical cord, atrial fluid, and vitreous humor of the eye. It has a high degree of viscoelasticity, plasticity, and good biocompatibility, and has a significant role in preventing adhesions and repairing soft tissues. It is used clinically for a variety of skin injuries to promote wound healing, and is effective for abrasions and lacerations, ulcers of the legs, diabetic ulcers, pressure ulcers, and debridement and venous stasis ulcers. Sodium vitrate is the main component of synovial fluid and is one of the components of cartilage matrix. It plays a lubricating role in the joint cavity, covers and protects articular cartilage, improves joint contracture, inhibits the surface of cartilage degeneration changes, improves pathological joint fluid, and increases lubrication function.
