  • Drug delivery device
    Patent number: 6277401
    Abstract: A drug delivery device includes (a) a substantially moisture vapor permeable, liquid impermeable, flexible thermoplastic backing layer, (b) a moisture vapor permeable, flexible, oleophilic thermoplastic resin foam layer, (c) a pressure sensitive adhesive layer, and (d) a drug reservoir containing at least one hydrophilic drug composition and possessing a moisture vapor permeable, but hydrophilic drug composition impermeable, barrier layer applied to one surface thereof with the drug reservoir being applied to a portion of the adhesive layer such that the barrier layer lies between the hydrophilic drug composition and the adhesive layer thereby preventing any significant migration of the drug composition from the drug reservoir into the adhesive layer.
