The aim of this study was to investigate the behavior of promising penetration enhancers through the use of 2 different skin test systems. Hydrogel-based transdermal formulations were developed with ibuprofen as a nonsteroidal anti-inflammatory drug. Transcutol and sucrose esters were used as biocompatible penetration enhancers. The permeability measurements were performed with ex vivo Franz diffusion cell methods and a newly developed Skin Parallel Artificial Membrane Permeability Assays (PAMPA) model. Franz diffusion measurement is commonly used as a research tool in studies of diffusion through synthetic membranes in vitro or penetration through ex vivo human skin, whereas Skin PAMPA involves recently published artificial membrane-based technology for the fast prediction of skin penetration. It is a 96-well plate-based model with optimized artificial membrane structure containing free fatty acid, cholesterol, and synthetic ceramide analog compounds to mimic the stratum corneum barrier function. Transdermal preparations containing 2.64% of different sucrose esters and/or Transcutol and a constant (5%) of ibuprofen were investigated to determine the effects of these penetration enhancers. The study demonstrated the good correlation of the permeability data obtained through use of human skin membrane and the in vitro Skin PAMPA system. The Skin PAMPA artificial membrane serves as quick and relatively deep tool in the early stages of transdermal delivery systems, through which the enhancing efficacy of excipients can be screened so as to facilitate the choice of effective penetration components.
本研究的目的是通过使用2种不同的皮肤测试系统来研究有前景的渗透促进剂的行为。以布洛芬作为非甾体抗炎药,开发了基于水凝胶的透皮制剂。使用二甲基亚砜和蔗糖酯作为生物相容性渗透促进剂。采用离体Franz扩散池法和新开发的皮肤平行人工膜渗透测定法(PAMPA)进行渗透率测量。Franz扩散测量通常用作体外通过合成膜扩散或通过离体人皮肤渗透研究的研究工具,而皮肤PAMPA涉及最近发表的基于人工膜的技术,用于快速预测皮肤渗透。它是一种基于96孔板的模型,具有优化的人工膜结构,包含游离脂肪酸、胆固醇和合成神经酰胺类似物化合物,以模拟角质层屏障功能。研究了含有2.64%不同蔗糖酯和/或二甲基亚砜以及5%恒定含量布洛芬的透皮制剂,以确定这些渗透促进剂的效果。该研究证明了通过使用人皮肤膜和体外皮肤PAMPA系统获得的渗透率数据具有良好的相关性。皮肤PAMPA人工膜在透皮给药系统的早期阶段作为一种快速且相对深入的工具,通过它可以筛选辅料的增强效果,以便于选择有效的渗透成分。
