Abstract

A method and device for enhanced transdermal drug delivery are disclosed. According to one embodiment of the present invention, the method includes the steps of (1) identifying an area of biological membrane: (2) contacting at least one high-permeability polysaccharide with the identified area of biological membrane; (3) contacting at least one drug with the identified area of biological membrane; and (4) transporting the at least one drug into or through the identified area of biological membrane. According to another embodiment of the present invention, a method for the enhanced transport of a drug into or through a biological membrane includes the steps of (1) preparing a complex of the drug with a high-permeability polysaccharide; and (2) transporting the complex into or through the biological membrane. According to another embodiment of the present invention, a device for enhanced drug delivery includes at least one high-permeability polysaccharide and at least one drug. The device may also include a contact layer that contacts a biological membrane and a medium layer containing the at least one high-permeability polysaccharide and the at least one drug .
