Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Ethosomes are attractive vesicular carriers mainly composed of phospholipids, ethanol and water. The intriguing features of ethosomes are due to their high ethanol content which facilitate their penetration through stratum corneum and target deep skin layers. This is advantageous over conventional liposomes which have limited penetration through the skin and remain confined in the upper layer of the stratum corneum. Compared to liposomes, ethosomes had greater retention of methotrexate into the skin for a longer period of time, suggesting better therapeutic outcome.
