A Review on Hydrophilic Matrix Polymers
A Review on Hydrophilic Matrix Polymers
Modified drug delivery systems are advantageous than conventional drug delivery systems in providing prolonged release of drug, releasing drug at specific site of action, reducing side effects, and reducing frequency of dosing. Modified drug delivery systems include extended release systems, sustained release systems etc.1,2 Extended release systems are divided into several types in which matrix type is one. In matrix systems, several polymers are used to prolong the release rate of the drug. This article briefly depicts the polymers used in matrix systems for providing prolonged release rate of drug reducing side effects and providing optimum therapeutic action.
