Mathematical models for bulk erosion type drug delivery systems / 中国组织工程研究

ABSTRACT

Bulk erosion type biodegradable materials play an important role in pharmaceutics.However,the instability of carriers affects drug delivery systems critically,and complicates their drug release kinetics.Among these problems,how degradation and erosion affect drug release patterns becomes a focus.Mathematical models facilitate to understand complex pharmaceutical drug release patterns,and are easily applied in structure design of drug delivery systems and to predict their drug release kinetics.This paper reviews the degradation and erosion patterns,drug release mechanisms,and the recent research of mathematical models.
