• Itraconazole (ITZ)
• HP beta CD
• Deformable liposomes
• Ex vivo penetration
• Antifungal activity

The study aimed to develop novel ITZ-loaded deformable liposomes (DL) in presence of hydroxypropyl-beta-cyclodextrin (HP beta CD) (DL-CD) to enhance antifungal activity. These formulations have been reported as conceivable vesicles to deliver drug molecules to the skin layers. The efficiency of the prepared systems was compared with conventional liposomes (CL) and ITZ solution. The developed liposomes were characterized for particle size, entrapment efficiency (EE %), deformability, stability, and morphology of the vesicles. In addition, ex vivo penetration and antifungal activity were evaluated. It was found that the presence of HP beta CD played a significant role in reducing the vesicle size to nano range. The deformability study and TEM images revealed that membrane deformability of DL and DL-CD was much higher than that of CL. Moreover, DL CD enhanced the amount of ITZ in SC and deeper skin layers compared to DL and CL The antifungal activity of ITZ-loaded deformable liposomes remained intact compared to ITZ solution. It can be concluded that deformable liposomes in the presence of HP beta CD may be a promising carrier for effective cutaneous delivery of ITZ.
