Abstract
A transdermal delivery system for the modulated administration of drugs is described. The drug delivery device comprises a backing; a drug reservoir containing the drug, a plasticizer-type enhancer, a solvent-type enhancer, and optionally, a gelling agent; a non-rate-controlling membrane; and an adhesive layer containing a plasticizer-type enhancer. This drug delivery system is particularly useful for the administration of tolerance-inducing drugs, for example, vasodilators, such as isosorbide dinitrate.
