Abstract
Method and therapeutic system in the form of a bandage for providing chemotherapy transdermally by administering certain drugs to unbroken skin in an initial priming dose that quickly brings the systemic concentration of drug to a therapeutic level, followed by a substantially constant dosage that holds said level. The bandage is a four-layer laminate of, from the top: a protective backing; a drug reservoir lamina that is the source of the constant dosage; a microporous membrane that controls the constant dosage rate; and an adhesive layer that is the source of the priming dose and the means by which the bandage is attached to the skin.
