Abstract
A method of drug delivery utilizes a transdermal device that contains a phase change material and a first material such as a drug, a pharmaceutical, or a medicament mixed with or disposed near the phase change material. The phase change material is one that transitions from solid to liquid form when heated. A second material is disposed, suspended, or held in the solid form of the phase change material. The phase change material changes to a liquid state in response to heat and the second material that is disposed, suspended, or held in the phase change material is released and comes into contact with the first material. Advantageously, such second materials may include substances such as pharmaceuticals that boost or supplement the effect produced by a drug delivered transdermally by the device, or drug antagonists, or nicotine.
