Nicotine patch

Nicotine patch is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Nicotine patch rather than just read about it. In short: 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.

Reference excerpt

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 U.S. Food and Drug Administration, it is considered one of the safer NRTs available for the treatment of tobacco use disorder. Nicotine replacement products including gum and transdermal patches are on the World Health Organization's List of Essential Medicines.

Medical uses A 2018 meta-analysis found that fewer than 20% of people treated with nicotine replacement therapy remain abstinent from smoking at one year.

History The first study of the pharmacokinetics of a transdermal nicotine patch in humans was published in 1984 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. Frank Etscorn filed a patent in the United States on January 23, 1985 and was issued the patent on July 1, 1986. The University of California filed a competing patent application nearly three years after Etscorn's filing on February 19, 1988, which was granted on May 1, 1990. 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.

Research Research has shown that NRT in combination with cognitive behavioral therapy (CBT) can improve the rates of smoking cessation in pregnant women. CBT counseling includes motivational interviewing, Transtheoretical Model of Behavior Change, and Social Cognitive Theory. Nicotine patches are under study to help relieve the symptoms of postoperative pain and to treat early dementia. Studies are being conducted about the use of transdermal nicotine patches to treat anxiety, depression, and inattentiveness in subjects with attention deficit hyperactivity disorder and to treat late-life depression. Two small studies have shown that transdermal nicotine patches improve some symptoms of ulcerative colitis. 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.

Application The patch is typically worn for 16 to 24 hours. Patches can be removed at night prior to bed if vivid dreams are experienced and undesirable.

Side effects A study published in the medical journal JAMA Internal Medicine in 2015 found that the most common side effects experienced when using a nicotine patch include: cough, headache, nausea, light-headedness, insomnia, disturbing dreams, sweating, watery eyes, shortness of breath, and skin irritation at the application site. The same study found that the following side effects were reported by patch wearers less frequently: diarrhea, dizziness, coldness in limbs, vomiting, and fast or pounding heart beat.

Availability Nicotine patches are available for purchase over-the-counter from various manufacturers, without a prescription.

Worked examples

Example 1 — a first encounter with Nicotine patch

Start with the simplest possible case. Write down what Nicotine patch claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nicotine patch before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nicotine patch ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nicotine patch

In research: Nicotine patch appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Nicotine patch in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Nicotine patch is common in secondary-school and first-year university syllabi. It links to neighbouring topics American inventions, Nicotine, Smoking cessation, so understanding it makes those chapters shorter.
In everyday life: Look for Nicotine patch outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Nicotine patch in simple terms?

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.

Why does Nicotine patch matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Nicotine patch?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
