Patent ID: 8383149

Claim:
A device for transdermal administration of drug to an individual through a body surface, comprising: an adhesive drug reservoir including at least one drug, at least one permeation enhancer, and an acrylate polymer, wherein the at least one drug and the at least one permeation enhancer are dissolved in a combined amount of at least 30 wt % in the acrylate polymer, and the acrylate polymer has a T g of greater than −10° C. without the at least one permeation enhancer and without the at least one drug, the acrylate polymer comprising a soft monomer component of no more than 40 wt %, 40 wt % or more of a hard monomer component, at least a portion of the hard monomer component being hard polar functional monomer, and 10 to 35 wt % of a polar functional monomer component, at least a portion of the polar functional monomer component being hard polar functional monomer, the adhesive drug reservoir being applicable as a pressure-sensitive-adhesive to the body surface of the individual for transdermal delivery of the at least one drug.
