Improved Drug Delivery Using Tough Hydrogel that Acts as a Synthetic Skin


For many years, the achievement of continuous release of medication has been the focus of controlled drug release research. An on-demand control of drug delivery is desired in many clinical situations, as it promises to improve therapeutic efficacy and lessen side effects. Hydrogels are an ideal candidates given they respond to changes in the environment including pH, temperature, light, electric fields, and magnetic fields. Unfortunately, such triggers to do not transfer to clinical environments well. There is a need for improved methods of delivering pharmaceutical drugs to patients.

Technology Summary

Purdue University researchers have developed the use of tough multiple-network hydrogels for the reliable delivery of water-soluble drugs dissolve in this medium.  The dissolved drugs are released from the hydrogel in a controlled fashion, suppressing the initial burst release of drugs and providing a reliable mechanism to controllably release drugs into a local area.  Some of the hydrogels utilized have similar mechanical properties to skin.  This provides greater comfort for a patient and allows for utilization in difficult applications areas like joints, e.g., knees, elbows.
