SYSTEM FOR CONTROLLED DRUG DELIVERY COMPRISING BIODEGRADABLE POLYMER MICROPARTICLES

摘要

The present invention relates to systems for controlled release, such as controlled drug release. In particular, it relates to systems comprising biodegradable polymer microparticles based on hydrophilic polysters having pendant hydroxyl groups and obtainable from water-in-oil-in-water emulsions for controlled release of drugs and therapeutics, such as DNA, proteins, peptides. Further, the invention relates to a method to prepare such systems and the use of such systems.
