Biodegradable Polymer-Based Controlled Release Systems: The Physicochemical Aspects. Part I. Systems and Mechanisms

摘要

Typical systems biodegradable polymer-drugs for the treatment of different diseases are considered and also the dosage forms used therein. Biodegradable polymers are classified as to degradation mechanism, hydrolysis mechanism and solubilization mechanism. Influence of the distribution type of drug in biodegradable polymer is described in relation to release rate.
