Abstract
A transdermal delivery device for delivering drugs, typically ionized drugs, from an aqueous reservoir is described. The device comprises an aqueous drug reservoir in the form of a gel confined between an impermeable backing member and a porous support structure. In preferred embodiments the support structure is the substrate to which is applied a porous or patterned in-line adhesive. A strippable release liner is preferably provided on the adhesive while in the package. The devices are usable to deliver drugs such as chlorpheniramine maelate, brompheneiramine maleate and scopolamine hydrobromide.
