Polyanhydrides for controlled release of bioactive agents.

Published

Journal Article

This report is a review of the development of a drug delivery system based on biorodible polyanhydrides. With the water labile anhydride linkage, a wide range of matrix degradation and drug release rates can be obtained from these drug-carriers. In addition to monolithic formulations, the feasibility of an injectable system by microencapsulation is demonstrated. The possibility of enhancing the release externally by an ultrasonic source has also been explored. The polymers tested showed good tissue biocompatibility and their breakdown products showed no adverse toxicological effects. Preliminary in vivo results confirmed the efficacy of these devices.
