Research progess on the transdermal mechanism of several liposomes

It is a promising method to use Liposomes as a carrier in the transdermal delivery system.Presently,llposomes,deformable liposomes,and ethosomes are in common use.The transdermal mechanism of the liposomes is to promote the velocity and the amount of the drugs of transdermal absorbance by affecting the keratoderma,acting on the skin appendages and changing the exterior characteristic of the drugs to make them permeate the skins.The Mechanism of the actions includes hydration.penetration,transforamation,and osmotic pressure driving effect,etc.The liposomes have been approved to have abroad prospect of application in the transdermal delivery system. Key words: Lipid vesicles; Liposomes; Deformable liposomes; Ethoeomes; Transdermal mechanism of action
