Crosslinked butyrate or butyrate-formate derivatives of hyaluronic acid and the crosslinking thereof |
| abstract |
The present invention relates to a process for the preparation of crosslinked hyaluronic acid butyrate or crosslinked hyaluronic acid butyrate-formate or an acceptable salt thereof, wherein the process comprises the crosslinking reaction of hyaluronic acid butyrate or hyaluronic acid butyrate-formate or a pharmaceutically acceptable salt thereof in an organic solvent with a carboxyl activating reagent, characterized in that the hyaluronic acid butyrate or hyaluronic acid butyrate-formate or pharmaceutically acceptable salt thereof is a mixture of a high-molecular-weight polysaccharide and a low-molecular-weight polysaccharide. |
