The device can comprise at least one core with a first active pharmaceutical ingredient (API), coated with a first layer that is permeable or semi-permeable to the API, coated with a second layer that is impermeable to the API, and having a delivery window to allow passage of the API through the device and into body fluids or tissues. The device can also have a wicking material to modify the rate of transport of the API into the body fluid or tissues.
