Injection grade sodium hyaluronate

Product Brief

Sodium hyaluronate is a main component of connective tissue such as human intercellularsubstance, vitreous body,and synovial fluid,etc,and has the characteristics of retaining water,maintaining extracellular space,regulating osmotic pressure,lubricating,and promoting cell repair.
Pharmaceutical sodium hyaluronate is divided into two categories according to the application,eye drops grade and injection grade.Injection grade sodium hyaluronate has good functions of moisturizing,lubricating,viscoelasticity,repairing damage cartilage,inhibition of inflammation,pain relief, etc,and can be used for ophthalmic viscosurgical devices and intra-articular injection.
Hyaluronic acid injections are injectable agents could be used to treat knee and hip pain and any other symptoms of osteoarthritis.
In a healthy joint, a thick, slippery substance called synovial fluid provides lubrication, allowing bones to glide against one another. It is especially important in preventing wear and tear by keeping the bones slightly apart and acting as a shock absorber.
In individuals with osteoarthritis, an important substance in synovial fluid, known as hyaluronic acid, breaks down. Reduction of hyaluronic acid can lead to joint pain and stiffness.
