N-palmitoylethanolamine and N-acetylethanolamine are effective in asteatotic eczema: results of a randomized, double-blind, controlled study in 60 patients
Randomised controlled trialHumansTopicalWith acetylethanolamine
This study tested palmitoylethanolamide together with acetylethanolamine. Its results cannot be assigned to palmitoylethanolamide alone. More combination studies.
- Design
- Randomised controlled trial
- Subjects
- 60 women with mild to moderate asteatotic eczema on the lower legs, at one centre in Shanghai
- Dose used in the study
- An emollient with 0.3% palmitoylethanolamide and 0.21% acetylethanolamine, applied twice a day, compared with an emollient without them
- Duration
- 28 days
- What was measured
- Clinical scores for redness, scaling, dryness and itch. Skin hydration, water loss through the skin, and a nerve sensitivity threshold.
What the authors reported
The authors reported that both emollients improved the skin measures. They reported greater improvement in scaling and dryness at day 28 with the palmitoylethanolamide emollient (P < 0.05), and a return of the nerve sensitivity threshold to normal levels. No adverse events occurred with either product.
Limits of this study
The two emollients differed in more than one ingredient, so the difference cannot be assigned to palmitoylethanolamide alone. All participants were women at one centre, and the study ran for 28 days. The study was supported by GlaxoSmithKline China. The test product was made by Stiefel Laboratories.
