The objective of the research was to develop and evaluate ibuprofen (Ibu) loaded spanlastics as an efficient wound healing treatment. Ibu- loaded vesicles were prepared employing ethanol injection technique using three edge activators; Tego® care 450, Cremophor RH 40 and Crodafos™ CES along with Span 60. Entrapment efficiency percentage (EE%), vesicular size and zeta potential were evaluated to select the optimal formulations. In- vitro release study, differential scanning calorimetry, xray diffraction and transmission electron microscopy were performed. Selected formulations were incorporated in a hydrogel to assess their in-vivo wound healing efficiency using full-thickness wound model. The vesicles exhibited high EE% (60.6-93.9 %), particle size ranged from 114.8 to 663.5 nm and zeta potential was from -26.2 to -42.3 mV which indicated good stability. In-vitro release pattern was biphasic. In-vivo assessment of wound healing efficacy of selected Ibu-loaded spanlastics disclosed significant reduction of wound size. A significant inhibition in TNF-α secretion as well as increased production of VEGF and Col-1 were noticed in rats treated with topical application of Ibu-spanlastics and an almost normal histological structure was observed in their microphotographs. These results confirmed that spanlastics might be a peculiar delivery system for Ibu to improve its topical wound healing efficacy.
该研究的目的是开发并评估负载布洛芬(Ibu)的泡囊弹性体作为一种有效的伤口愈合治疗方法。采用乙醇注入技术,使用三种边缘活化剂(Tego® care 450、聚氧乙烯蓖麻油RH 40和Crodafos™ CES)以及司盘60制备负载Ibu的囊泡。评估包封率(EE%)、囊泡大小和zeta电位以选择最佳配方。进行了体外释放研究、差示扫描量热法、X射线衍射和透射电子显微镜检查。将选定的配方加入水凝胶中,使用全层伤口模型评估其体内伤口愈合效率。囊泡表现出高包封率(60.6 - 93.9%),粒径范围为114.8至663.5 nm,zeta电位为 - 26.2至 - 42.3 mV,这表明具有良好的稳定性。体外释放模式为双相。对选定的负载Ibu的泡囊弹性体进行伤口愈合功效的体内评估,结果显示伤口大小显著减小。在用Ibu - 泡囊弹性体局部给药治疗的大鼠中,观察到肿瘤坏死因子 - α分泌受到显著抑制,同时血管内皮生长因子(VEGF)和I型胶原蛋白(Col - 1)的产生增加,并且在其显微照片中观察到几乎正常的组织结构。这些结果证实,泡囊弹性体可能是Ibu的一种特殊递送系统,可提高其局部伤口愈合功效。
