Abstract

The present invention pertains to biodegradable sustained-release composins capable of achieving the sustained release of a pharmaceutical or other agent. The compositions can be formed into implant devices which may be used to treat a wide variety of diseases and conditions. The implants are especially useful in treating diseases such as periodontal disease which require prolonged drug release.
