Abstract
Transdermal delivery systems for delivery of fentanyl and its analgetically effective derivatives for extended periods of time are disclosed which deliver the base form of the drug at a rate of from 0.5 to 10 .mu.g/cm.sup.2 /hr for a substantial portion of their useful life. The systems can be from 5-100 cm.sup.2 in releasing surface and preferably employ an in-line amine resistant adhesive. Preferred rate controlled systems utilize an aqueous ethanolic gel to minimize drug content.
