Chapter 2 Overview of Controlled Release Mechanisms

  title={Chapter 2 Overview of Controlled Release Mechanisms},
  author={Ronald A. Siegel and Michael John Rathbone},
Controlled release systems have been developed to improve the temporal and spatial presentation of drug in the body, to protect drug from physiological degradation or elimination, to improve patient compliance, and to enhance quality control in manufacturing of drug products. When designing controlled-release systems, it is important to identify and understand particular mechanisms involved in the release process. Often, more than one mechanism is involved at a given time or different… CONTINUE READING
