Abstract
A transdermal drug delivery system in which drug delivery is biphasic is provided. Drug is delivered at a therapeutically effective rate during an initial, delivery phase, typically of about 10 to 14 hours, followed by a subsequent, secondary phase during which virtually no drug is delivered. Substantially all of the drug initially loaded into the device is delivered within the initial, delivery phase.
