| 摘要 |
The present invention relates to stable polymer matrix compositions comprising high concentrations (from about 1.5% w/w to about 3.5% w/w) sodium hyaluronate obtained from a Streptococcus zooepidemicus source and a non-ionic polymer. The polymer matrix composition further comprises polyethylene glycol and methylparaben, and utilizes ingredients that are of pharmaceutical or compendial grade. The polymer matrix compositions may optionally comprise an active ingredient. The present polymer matrix compositions may be used in the treatment of wounds, burns, certain dermatological conditions, vaginal dryness, and in topical, transdermal delivery and sustained release of active ingredients. |
