Time-Dependent Differences in the Effects of Oleic Acid and Oleyl Alcohol on the Human Skin Barrier
Popis výsledku v původním jazyce
Oleic acid and oleyl alcohol are commonly used permeation and penetration enhancers to facilitate topical drug delivery. Here, we aimed to better understand the mechanism of their enhancing effects in terms of their interactions with the human skin barrier using diclofenac diethylamine (DIC-DEA), a nonsteroidal anti-inflammatory drug for topical pain management. Oleic acid promoted DIC-DEA permeation through ex vivo human skin more rapidly than oleyl alcohol (both applied at 0.75%) due to fluidization of stratum corneum lipids as revealed by infrared spectroscopy. After 12 h, the effect of these enhancers on DIC-DEA permeation leveled off, fluidization was no longer evident, and skin permeabilization was mainly due to the formation of fluid enhancer-rich domains. Contrary to oleyl alcohol, oleic acid adversely affected two indicators of the skin barrier integrity, transepidermal water loss and skin electrical impedance. The content of oleyl alcohol in the stratum corneum was lower than that of oleic acid (even 12 h after the enhancers were removed from the skin surface), but it caused higher DIC-DEA retention in both epidermis and dermis compared to oleic acid. The effects of oleyl alcohol and oleic acid on DIC-DEA permeation and retention in the skin were similar after a single and repeated application (4 doses every 12 h). Thus, oleyl alcohol offers several advantages over oleic acid for topical drug delivery.
