Eye drops grade sodium hyaluronate

Short Description:

Sodium hyaluronate can significantly improve the bioavailability of drugs through its physical thickening, membrane affinity, and combination with drugs. Its advantages are unmatched by other polymer materials. It can also be modified by cross-linking and restructuring to prolong the retention time in the eye and further increase the bioavailability of the drug.
