Abstract:
A multilayered drug delivery system with a barrier suitable for delivery of drug through an individual's body surface. By placing a barrier between two adjacent layers, unintended drug flow due to migration of a drug matrix between the adjacent matrix layers in the system to a patient is avoided.
