ABSTRACT
Introduction/ Background: This study aimed to introduce a gel (NEG) formulation containing betulin-loaded nanoemulsions for topical psoriasis treatment.
MATERIALS AND METHODS: The prepared nanoemulsions were optimized for smaller particle size and higher drug content using a response surface methodology that exhibited uniform distribution and high drug loading (21.17±3.55%).
RESULTS: The gel demonstrated skin-compatible pH and good spreadability. The developed gel showed slower release compared to nanoemulsion. In vivo pharmacokinetics demonstrated elevated AUC (55835.1 μg/cm2.h) and extended Tmax (720 min) for the gel than NE, indicating extended skin retention. Improved skin hydration (35%) and lipid content (28%) were observed, along with significant reductions in PASI scores and cytokine levels.
DISCUSSION: Provided with enhanced skin retention, improved hydration, and lipid content, along with significant therapeutic efficacy in psoriasis treatment, betulin-loaded nanoemulsion gel demonstrated prolonged drug release and notably reduced PASI scores and cytokine levels, highlighting its effectiveness against psoriasis.
CONCLUSION: This highlights the promising potential of NEG for topical psoriasis management.
