Abstract
Pioglitazone (PGZ) is a peroxisome proliferator-activated receptor agonist. Its role in the inflammatory response modulation opens the door for additional therapeutic applications. The purpose of this study was to develop a pioglitazone nanoemulsion (PGZ-NE) to investigate its anti-inflammatory efficacy on the skin. For that a NE vehicle aimed for skin delivery was optimized and characterized. The resulting PGZ-NE showed a good anti-inflammatory efficacy by decreasing the expression of adipose inflammatory cytokines IL-6, IL-1β and TNF-α. The properties of the developed nanocarrier allowed achieving a high permeation flux of PGZ through the skin as well as high retained amount in the skin, probably due to the depot effect of ingredients, which assured a prolonged local action, with good skin tolerability among participating individuals. Consequently, these results suggest that PGZ-NE may be used as an alternative treatment for inflammatory skin diseases such as rosacea, atopic dermatitis or psoriasis.
