Polyvinyl Alcohol/Chitosan Hydrogels for Ionthopheretic Drug Delivery Systems

摘要

Research into materials and methods to improve the delivery of drugs in the human body is presently at an all time high. Ionthophoresis can be considered as one of the newer methods of drug delivery, whereby drugs ions are "pushed" through the skin to the underlying tissue when a low-level electrical charge is applied. The main advantage of ionthophoresis is its ability to deliver drugs directly to the treatment site, without the patient having to experience injections. The ionthophoresis method is considered superior to skin patches, especially with regard to water-soluble ionic drugs that are not easily absorbed through the skin.
