ABSTRACT:
A delayed onset transdermal drug delivery device exhibiting a delay period of at least six hours comprising a laminated composite of (12) a top backing layer; (13) a pressure rupturable layer underlying (12); (14) a reservoir of a solution of drug in a liquid vehicle between (12) and (13); (16) a wick layer underlying (13) for dispersing the drug once (13( is ruptured; (17) a polymer layer underlying (16) that is permeable to the drug; (18) a microporous membrane underlying (17) which is itself impermeable to the drug but whose pores are filled with a polymer that is immiscible in the adhesive and has a solubility parameter within two units of the solubility parameter of the vehicle; and (20) an adhesive layer underlying (18) that is permeable to the drug but is immiscible in the polymer filling the pores of (6).
