Stimulus-responsive transdermal drug delivery systems can achieve specific drug release and improve drug utilization. According to the different stimulation modes， these preparations can be divided into endogenous stimulus-responsive， exogenous stimulus-responsive and combined stimulus-responsive transdermal drug delivery systems. The endogenous stimulation- responsive transdermal drug delivery system can respond specifically to changes in temperature and pH of the lesion site through carrier materials， so as to deliver drugs to the target site. Exogenous stimulus-responsive transdermal drug delivery system can use light， heat， magnetic， electric and other external stimulation to make the carrier material phase change， so as to achieve drug delivery. The combined stimulus-responsive transdermal drug delivery system is a combination of two or more stimulus-responsive percutaneous drug delivery systems， such as temperature-pH dual-responsive drug delivery system. At present， the relevant studies of stimulus-responsive transdermal drug delivery systems are mostly in the experimental stage， and further evaluation of stability， toxicity and skin irritation is needed in the future to lay a theoretical foundation for clinical application.
