The aim of the present work was the optimization of the transdermal delivery of a lyotropic liquid crystal genistein-based formulation (LLC-GEN). LLC was chosen as medium in view of the poor solubility of GEN in water. Membrane diffusion and penetration studies were carried out with a Franz diffusion cell, through a synthetic membrane in vitro, a chick chorioallantoic membrane ex ovo, and ex vivo excised human epidermis. Thereafter, LLC-GEN was combined with electroporation (EP) to enhance the transdermal drug delivery. The synergistic effect of EP was verified by in vivo ATR-FTIR and ex vivo Raman spectroscopy on hairless mouse skin.
本研究的目的是优化基于溶致液晶染料木黄酮的制剂(LLC-GEN)的透皮给药。鉴于染料木黄酮在水中的溶解度较差,选择了液晶作为介质。使用Franz扩散池,通过体外合成膜、鸡胚绒毛尿囊膜和离体切除的人表皮进行了膜扩散和渗透研究。此后,将LLC-GEN与电穿孔(EP)相结合以增强透皮给药。通过体内衰减全反射傅里叶变换红外光谱(ATR-FTIR)和体外拉曼光谱对无毛小鼠皮肤验证了电穿孔的协同作用。
