GEL COMPOSITION COMPRISING CHARGED POLYMERS

摘要

Aqueous gel compositions are disclosed which are useful as drug carriers for controlled delivery applications, such as for parenteral depot formulations. The gels comprise ionically charged microparticles, and preferably mixtures of oppositely charged microparticles. The microparticles can be loaded with active compounds, such as therapeutic peptides and proteins. The gels can be prepared by combining oppositely charged microparticles in the presence of water.
