- 材料科学 材料科学 材料科学
背景情况:
- 像维生素C衍生物这样的活性成分的局部输送需要优化配方,以提高皮肤透和保留.
- 基于脂质的凝系统提供了可控释放和改善与皮肤角层相互作用的潜力.
- 3-O-乙烯L-甲酸 (ETVC) 是维生素C的稳定和有效衍生物,具有抗氧化特性.
研究的目的:
- 将10%的3-O-乙L-酸 (ETVC) 纳入两个不同的脂质凝系统:水凝 (HG) 和大 (BG).
- 评估来自HG和BG两种配方的ETVC在体外释放动力学,皮肤透和角层相互作用.
- 在猪皮肤模型中评估带有ETVC的脂质凝的抗氧化疗效.
主要方法:
- 制备含有10%ETVC的水凝 (HG) 和大面包 (BG) 配方.
- 使用合成膜进行体外释放研究以量化ETVC扩散.
- 通过猪皮肤进行ex vivo透研究,以测量ETVC向不同皮肤层 (角质层和表皮层) 的传递.
- 使用甲蓝的层状角质脂质结构分析和体外抗氧化活性测试.
主要成果:
- 与水凝 (HG) 相比,大凝 (BG) 配方的ETVC释放速度明显较慢.
- 这两种脂凝系统都提高了皮肤内的ETVC保留率,HG向角层提供了更多,BG实现了更大的表皮保留.
- 角层的脂质组织不受凝应用的影响,而ETVC凝在体外显示出显著的抗氧化活性.

Lipid Absorption
3.9K
Dietary triglycerides from chyme in the duodenum are mixed with bile salts produced by the liver to emulsify fats. As a result, large droplets are broken down into smaller ones, increasing the surface area for enzymatic action. Once emulsified, pancreatic lipases hydrolyze the triglycerides into free fatty acids and monoglycerides.
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...

Ophthalmic Drug Delivery Systems

Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...
