Abstract

Provided is a transdermal drug delivery system, which is a delivery system for transdermal absorption, having a multi-lamellar emulsion structure, including: lipids including long-chain amides, sterols, fatty acid and fatty alcohol; an emulsifier; oil; and at least one drug for transdermal administration. The transdermal drug delivery system in a multi-lamellar emulsion structure, according to the present invention, has a lamellar structure in which a layered structure visible in stratum corneum intercellular lipids of the human body is repeated, and thus has an excellent skin barrier effect and enables a drug to be effectively partitioned through skin lipids, thereby obtaining an excellent drug delivery effect.
