SUMMARY OF THE INVENTION The present invention is directed to a hydrogel composition for transdermal drug delivery, and more particularly, to a hydrogel composition wherein both a hydrophilic permeation enhancer and a lipophilic permeation enhancer are used to effectively regulate the skin penetration of the drug. The invention relates to a hydrogel composition for transdermal drug delivery comprising an acrylate polymer, such as an acrylic acid polymer, a methacrylic acid polymer, an alkyl acrylate polymer, an alkyl methacrylate polymer or a copolymer thereof, as a compatibilizer enabling it to be applied to pharmaceutical compositions. |
