Abstract
The present invention is directed toward a formulation for supplying additional drug for delivery in a transdermal drug delivery device. The invention comprises a drug, such as fentanyl that is capable of transdermal delivery, and a solution having a pre-designed solubility for the drug. The solution dissolves only a portion of said drug and allows a significant portion of the drug to remain undissolved in solution, thus providing extra drug to be delivered at a consistent, controlled delivery rate. The invention may used in conjunction with controlled heat.
