International ClassA61F 013/00AbstractA novel transdermal delivery system for nicotine to satisfy addicted smokers' cravings therefore is comprised of a nicotine base, an acrylate polymer adhesive, a stabilizer and a polyester film backing. The nicotine is absorbed through the skin at sufficiently high levels to reduce or eliminate the desire to smoke, yet its concentration within the acrylate matrix is such that a laminar patch is constructed that is neither bulky nor obvious when worn. A method of manufacture of the transdermal system is also described. | |
