Abstract

Transdermal drug delivery system is a novel approach of controlled drug delivery that aims to deliver drugs through the skin at a predetermined and controlled rate. Hydrogels are three dimensional network of hydrophilic polymers which can retain significant volume of water without disrupting the structure. Hydrogel based transdermal patches provide a cooling effect for the skin over conventional patches which results in better patient compliance. Also, hydrogel based transdermal patches have excellent biocompactibility,High mechanical strength, reproducibility and biodegradability.
