The purpose of this work is to develop novel lipid-based self-nanoemulsifying drug delivery systems (SNEDDS) as carriers for transdermal delivery of curcumin. SNEDDS containing black seed oil, medium chain mono- and diglycerides and surfactants, were prepared as curcumin delivery vehicles. Their formation spontaneity, morphology, droplet size, and drug loading were evaluated. Gel preparation containing two of the SNEDDS formulations were used in the carrageenan induced paw edema to evaluate the anti-inflammatory effect. Results showed droplet size as low as 71 nm. The highest drug loading was observed with SNEDDS-F6 of ∼45 mg/g. In investigation, SNEDDS-F6 exhibited significant anti-inflammatory activities in terms of 80% reduction in paw edema when compared with positive control. The prepared SNEDDS with the elevated entrapment efficiency, good transdermal penetration ability could be a suitable candidate for effective transdermal curcumin skin delivery.
本工作旨在开发新型基于脂质的自微乳药物传递系统(SNEDDS)作为姜黄素经皮传递的载体。含有黑种草油、中链单甘酯和双甘油脂和表面活性剂的 SNEDDS 被制备为姜黄素的递送载体。评估了它们的形成自发性、形态、粒径和载药量。含有两种 SNEDDS 配方的凝胶制剂用于角叉菜胶诱导的足肿胀来评估抗炎作用。结果显示粒径低至 71nm。最高载药量观察到 SNEDDS-F6 约为 45mg/g。在研究中,与阳性对照相比,SNEDDS-F6 在减轻足肿胀方面表现出显著的抗炎活性,减少了 80%。具有提高的包封效率和良好的经皮渗透能力的制备 SNEDDS 可能是有效经皮姜黄素皮肤递送的合适候选物。
