Ethosomes are phospholipid nanovesicles used for dermal and transdermal delivery of molecules. They. Structure and composition[edit]. Ethosomes are mainly. 8 Oct Now a days liposomes, niosomes, transferosomes and ethosomes (vesicular and non invasive drug delivery)are used to increase the. The objective of work was to formulate, evaluate and compare the transdermal potential of novel vesicular nanocarriers: ethosomes and ultradeformable.

Ethosomal carrier opens ethowomes challenges and opportunities for the development of novel improved therapies. Ethosomes were prepared as reported by Touitou et al. Support Center Support Center.


Finally, traces of solvent mixture are removed from the deposited lipid film by leaving the contents under vaccum overnight. The physical means like iontophoresis, microneedles, and sonophoresis are relatively complicated to use, and will affect patient compliance.

These soft vesicles represent novel vesicles carriers for enhanced delivery through the skin. This article has been cited by other articles in PMC. Reduction in mean vesicle diameter is due to the presence of ethanol, as it causes a modification of the net charge of the system and confers it some degree of stearic stabilization that may finally lead to a decrease in the mean vesicle size,[ 21 ] while the size of the vesicles increase with increasing the phospholipid concentration.

These flexible vesicles may become a promising carrier for the transdermal delivery of aceclofenac. Variation in propylene glycol concentration also influenced the amount of drug permeated. Cold method This is the most common and widely used method for ethosomal preparation.


One of the approaches for increasing the skin penetration of drugs and many cosmetic chemicals is the use of vesicular systems, such as, liposomes and ethosomes. In general, the epidermis specifically the stratum corneum provides the major control element; most small, water-soluble, and non-electrolytes diffuse into the systemic circulation a thousand times more rapidly when the horny layer is present.

The ethosomez of this small review is to introduce the novel concept of ethosomes and to describe some approaches and mechanisms of stimulating topical and transdermal products with ethosomes. Oral administration of hormones is associated with complications like high first pass metabolism, low oral bioavailability, and several dose-dependent side effects such as virilization, acne, and gynecomastia.

Ehhosomes Authors would like to express sincere gratitude towards Prof. Preparation of ethosomes containing aceclofenac: Ind J Pharm Sci. Elastic liposomal formulations for sustained delivery of Colchicine: Stability of ethosomes Stability of the formulations was evaluated in terms of the entrapment capacity and the particle size for a specified period.

Due to the amphiphilic nature, lipid vesicles may serve as non-toxic penetration enhancers for drugs.

Thus ethosomes can increase the transdermal flux, prolong the release and present an attractive route for sustained delivery of Zidovudine. Ethosomes increases skin penetration of entrapped and non-entrapped hydrophilic substances into human skin: The lipids present in the skin contribute to the barrier properties of the skin and prevent the systemic absorption of drugs. Nanoparticles aiming at specific targets — dermal and transdermal delivery. Many environmental pathogens attempt to enter the body through the skin.

Therapeutic Applications of Ethosomes Mishra et al.

The study was performed with phosphate buffer saline pH 7. Ethosomes are provides a number of important benefits including improving the drug’s efficacy, enhancing patient compliance and comfort and reducing the total cost of treatment.

Skin has, therefore, evolved into an excellent protective barrier, which is also immunologically active and able to express the gene. Furthermore, hydrolysis of lipids leads to the formation of lyso-PC. The commercialization of ethosome technology began inand it is a rapidly evolving field. Ind J Exp Biol. Colloidal suspensions of ethosomes were prepared by reported method. Ethosomes have been tested to encapsulate hydrophilic drugs, cationic drugs, proteins and peptides.

Preparation and Characterization of Ethosomes for Topical delivery of Aceclofenac

Ethosomes have ethosmes found to be much more efficient at delivering drug to the skin, than either liposomes or hydroalcoholic solution. Double distilled water is added in a fine stream to the lipid mixture, with constant stirring at rpm, in a closed vessel.

However, the exact mode and nature of deformable vesicle transport into and possibly across the skin is not yet fully understood.
