Dual-composite delivery system

Abstract

A drug delivery system, including a swelling polymer matrix, and a polymerized hydrophilic drug system is configured to control the release of the hydrophilic drug. Additionally, a method of using the drug delivery system 1, the method including providing the polymerized hydrophilic drug dispersed within the swelling polymer matrix, reaching a water equilibrium within the swelling polymer matrix, hydrolyzing the polymerized hydrophilic drug, and diffusing the hydrophilic drug outside of the swelling polymer matrix Further, A method of making the drug delivery system, the method including polymerizing a hydrophilic drug to produce a polymerized hydrophilic drug, and embedding the polymerized hydrophilic drug into a swelling polymer matrix.
