Nicotine patch

A 21 mg dose patch applied to the left arm

A nicotine patch is a transdermal patch that releases nicotine into the body through the skin. It is used in nicotine replacement therapy (NRT), a process for smoking cessation. Endorsed and approved by the Food and Drug Administration (FDA), it is considered one of the safer NRTs available.[1]

Medical uses

Dozens of clinical trials have shown that the patch nearly doubles success rates for smoking cessation over placebo treatment. Placebo tests show a 5.9% success rate, in comparison to 7.2% in blind active trials, and 10.8% in randomized control trials.[2][3]

History

The first study of the pharmacokinetics of a transdermal nicotine patch in humans was published in 1984[4] by Jed Rose, Murray Jarvik, and Daniel Rose, and was followed by publication by Rose et al. (1985) of results of a study of smokers showing that a transdermal nicotine patch reduced craving for cigarettes.[5] Frank Etscorn filed a patent in the United States on January the 23rd 1985 and was issued the patent on July 1, 1986.[6] The University of California filed a competing patent application nearly three years after Etscorn's filing on February the 19th, 1988, which was granted on May 1, 1990.[7] Subsequently, the U.S. Patent Office declared an interference action and, after a thorough review of conception, reduction to practice and patent filing dates, issued on September 29, 1993 a priority decision in favor of the Rose et al. patent.[8]

Research

Nicotine patches are under study to help relieve the symptoms of postoperative pain[9] and to treat early dementia.[10]

Studies are being conducted about the use of transdermal nicotine patches to treat anxiety, depression, and inattentiveness in subjects with ADHD[11] and to treat late-life depression.[12]

Transdermal nicotine patches can be used to relieve ulcerative colitis symptoms. However, this is not the case with Crohn's disease, a similar health condition, where smoking and nicotine intake in general worsen the disease's effects.
