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