HYALURONIC ACID BINARY MIXTURES AND THERAPEUTIC USE THEREOF

摘要

The present invention is related to hyaluronic acid compositions consisti ng in a binary mixtures of hyaluronic acid samples having mainly different w eight-average molecular weight and then different rheological properties in aqueous solution. The resulting compositions have demonstrated peculiar rheo logical behaviour with a balance between viscosity and viscoelasticity. Acco rdingly, these compositions of hyaluronic acid are useful for treatment of j oint diseases by intra-articular administration or extra-articular applicati on in soft tissue disorders.
