Transparent transdermal nicotine delivery devices

A device for transdermal nicotine administration, comprising:

• a laminate including a polymeric backing layer comprising a material selected from the group consisting of PET/EVA laminates, HDPE/EAA/nylon/EAA multilaminate and a film comprising a graft copolymer formed from 73-77% acrylonitrile and from 23-27% methyl acrylate copolymerized in the presence of 8-10 parts by weight of butadiene/acrylonitrile copolymers containing 70% by weight of polymer units derived from butadiene,
• a nicotine reservoir layer having nicotine carried by the backing layer,
• a rate control membrane near the nicotine reservoir to face the skin for controlling nicotine delivery to the skin, and
• adhesive for maintaining the device on the skin, wherein
• the device provides delivery of nicotine for a period of 18-24 hours and, as applied to the skin, exhibits an Opacity Index of less than 48.6% to permit the skin to which the device is applied to be visible through the device.
