Abstract
A transdermal delivery device has a reservoir containing an active compound, which is kept separate from the delivery layers of the device until administration. At the time of administration, the reservoir is laminated to the delivery layers, or is ruptured to place the active compound, vehicle, and/or permeation enhancers in contact with the delivery layers, which results in administration of the active compound to the skin after a delay period.
