Synvisc One intra-joint hyaluronic acid

Synvisc is a prefilled syringe containing a gel-like substance called hyaluronic acid. Synvisc prefilled syringe often injected into the knee joint.

Hyaluronic acid is a natural substance found in the synovial fluid that surrounds joints. Hyaluronic acid gel, founded in Synvisc, acts as a lubricant or emollient to enable bones to move smoothly over one another and as a shock absorber.

People with osteoarthritis usually have a lower than normal concentration of hyaluronic acid in their joints. The theory is that adding hyaluronic acid to an arthritic joint will facilitate movement and reduce pain.

Synovial fluid is a viscous substance found in the joint cavity, this fluid works to facilitate and lubricate the movement of the joint and help the joint to perform its function easily and prevent the occurrence of pain in the joint by limiting the friction of the joint bones.

In degenerative joint diseases (such as arthritis – Rheumatism or knee arthritis) the viscosity of the synovial fluid decreases, and thus pain, difficulty in movement, and swelling occur in the joints.

Synvisc injected locally into the affected joint (e.g. knee joint, hip, shoulder and elbow joint).

Synvisc does not cure or prevent knee joint arthritis, it is a preparation that has a temporary effect in relieving the symptoms of arthritis, such as relieving pain when moving or during rest, reducing swelling, and facilitating movement.

Synvisc reduces friction between the bones in the joint area, and this reduces the feeling of pain and delays the development (progress) of the condition, as well as reducing the patient’s need for analgesic, anti-inflammatory and cortisone drugs.

Synvisc belongs to a class of medicines called viscosity supplements.
