research The Physicochemical, Biopharmaceutical, and In Vitro Efficacy Properties of Freeze-Dried Dexamethasone-Loaded Lipomers
This study explored the use of dexamethasone-loaded polymer hybrid nanoparticles in a xanthan gum hydrogel for treating alopecia areata, finding that freeze drying with sucrose influenced particle size, release, and permeation, but had no impact on cytotoxicity or anti-inflammatory efficacy in human keratinocytes.
