Hydrogels for Controlled Drug Release

  • Sung Wan Kim


Hydrogels have been investigated for use in controlled-release drug delivery systems. Hydrogels show superior biocompatibility and permeation of both hydrophobic and hydrophilic drugs depending on the combination of copolymers. Drug diffusion through hydrogels depends on the hydrogel nature, mainly the percentage of cross-linking agents and hydrogel water content. Various devices designed with hydrogels are discussed in this chapter: reservoir systems, drug-dissolved monoliths, drug-dispersed monoliths, monolith devices with barrier layers, and novel delivery systems.
