The alteration of retinoids levels in the skin can cause different disorders in the maturation of epithelial skin cells. Topical administration of these lipophilic molecules is a challenge that can be addressed by encapsulation into drug delivery systems. In this study, retinyl palmitate transferosomes formulated in cream were developed and the increases in the penetration of the active ingredients as well as the biodistribution were evaluated in vitro and in vivo. Transfersomes demonstrated a significant increase in the administration of retinyl palmitate to the epidermis by quantification of the active ingredients in the different layers of the skin, as well as by fluorescence microscopy of biopsies of non-dermatomized pig-ear skin. These results suggest that transfersomes may be an efficient vehicle for the delivery of retinoids to inner layers of the skin, such as the epidermis.
皮肤中类视黄醇水平的改变会导致上皮皮肤细胞成熟过程中出现不同紊乱。局部施用这些亲脂性分子是一项挑战,可通过将其封装到药物递送系统中来解决。在本研究中,开发了乳膏剂型的棕榈酸视黄酯传递体,并在体外和体内评估了活性成分渗透及生物分布的增加情况。通过对皮肤不同层中活性成分的定量,以及对非去皮猪耳皮肤活检组织的荧光显微镜检查,传递体显示出棕榈酸视黄酯向表皮给药的显著增加。这些结果表明,传递体可能是将类视黄醇递送至皮肤内层(如表皮)的有效载体。
