ArtroSupp is a synovial fluid substitute which, thanks to its viscoelastic and lubricant properties, promotes restoration of rheological conditions of the joints, altered in degenerative or post-traumatic conditions. The sterile sodium hyaluronate gel, improving characteristics of the synovial fluid, exerts a protective action of the joints and helps the improvement of joint function and the reduction of pain symptoms. Artrosupp acts only at the joint where it is injected, without exerting any systemic action.
