Revolutionary Approach towards Transdermal Drug Delivery: Ethosomal Gels

The human body is up of the skin which is the largest organ in the body and hence acts as a biological barrier that obstructs drug movement across the stratum corneum into the systemic circulation. The topical drug delivery system serves as a delivery system in which drugs are delivered for systemic circulation through the skin. Low diffusion rate across the stratum corneum is the main disadvantage of this system and for this limitation to be overcome, an Ethosomal formulation can be formulated which acts as a delivery system for the drug to be delivered across the biological barrier of the skin into the body. In ethosomal gel formulation, The prepared Ethosome is converted into a gel that can be applied to the skin what makes ethosomal gel formulation unique which enables drugs to reach the deep skin layers and/or the systemic circulation and enhance the delivery of active agents. In addition to this, it is also a malleable vesicular delivery carrier, soft and non-invasive. There is also a higher influx of drugs transdermally into the skin as ethosomal gel formulation allows drug to penetrate deep into the skin and enters systemic circulation. There is the development of new and novel therapies for the treatment of disease through the ethosomal drug delivery system as it is safe and effective and also easy to prepare. Topics ranging from preparation of ethosomes, Ethosomal gel, advantages and disadvantages, and characterization techniques are focused on in this review article.
