Zero-order sustained release delivery system for carbamazephine derivatives

摘要

A zero-order sustained-release delivery system for delivery of carbamazepine or a derivative thereof. A polymeric matrix formulation of carbamazepine comprises hydrophilic polymer or hydrophilic/hydropholic polymer mixture which permits carbamazepine or carbamezepine derivative to be released from the polymer matrix in zero-order release kinetics.
