Abstract
Background: When administered transdermally, desonide is ineffective due to its poor solubility. As a new transdermal delivery system, nanoemulsion gel has demonstrated significant advantages for drug delivery over conventional formulations. We have established desonide nanoemulsion gel (DES NE gel) for better transdermal absorption, but its efficacy and safety still need to be evaluated. This study aims to provide additional evidence demonstrating the improved pharmacodynamics and safety of transdermal delivery of Desonide via nanoemulsion gel.
Methods: Pharmacodynamics and safety of Desonide nanoemulsion gel were evaluated using Desonate ® as the reference formulation. To assess the difference in curative effect between DES NE gel and Desonate® and to ensure safety, atopic dermatitis (AD) models in KM mice were developed using 2,4-dinitrofluorobenzene (DNFB). The degree of ear swelling, ear mass difference, thymus, spleen index, and HE conventional pathology of mice were used as pharmacodynamic evaluation indexes, and the irritation was predicted by the New Zealand rabbit epidermal stimulation assay.
Results: Nanoemulsion gels may facilitate transdermal penetration of drugs by influencing the skin condition. Medium and high doses of DES NE gel significantly ameliorated the inflammation and swelling of the ear caused by dermatitis/eczema in mice. In addition, compared with DES gel, skin irritation extent did not increase.
Conclusion: Nanoemulsion gel can be applied to improve the efficacy of drugs with low potency or poor solubility. DES NE gel provides a higher transdermal potential than other delivery systems. In this study, it was found that nanoemulsion gel is a promising percutaneous carrier of DES. DES NE-GEL has a significant curative effect on dermatitis/eczema in a mouse model and is expected to provide a new, efficient, and low toxic preparation for clinical treatment of dermatitis/eczema through the percutaneous system.
期刊介绍：
Current Drug Delivery aims to publish peer-reviewed articles, research articles, short and in-depth reviews, and drug clinical trials studies in the rapidly developing field of drug delivery. Modern drug research aims to build delivery properties of a drug at the design phase, however in many cases this idea cannot be met and the development of delivery systems becomes as important as the development of the drugs themselves.
The journal aims to cover the latest outstanding developments in drug and vaccine delivery employing physical, physico-chemical and chemical methods. The drugs include a wide range of bioactive compounds from simple pharmaceuticals to peptides, proteins, nucleotides, nucleosides and sugars. The journal will also report progress in the fields of transport routes and mechanisms including efflux proteins and multi-drug resistance.
The journal is essential for all pharmaceutical scientists involved in drug design, development and delivery.
