Nicotine and nicotine replacement therapy – Myths and Facts

Introduction

The effectiveness in helping cessation of NRT is well established and is supported from the greatest degree of clinical signs, systematic review of more than 90 randomized clinical trials.

Nicotine and nicotine replacement therapy

Smoking cessation guidelines from abroad and Australia urge that smokers be offered urge, and to help stopping, unless contraindicated NRT as a first-line therapy.

Guidance in the National Prescribing Service notes the same effectiveness of and NRT on signs that is present but urges NRT be used given outstanding security profile as well as its extensive clinical expertise. Achievement rates can be further enhanced by combining NRT with behavioral support.

Nicotine replacement therapy isn’t just powerful when NRT is quit by not buying cigarettes, the typical smoker will save in the order of $3000 per year, and it’s also cost effective, in a daily price which is roughly half that of smoking cigs.

This review addresses the common myths or misperceptions wall nicotine by summarizing the available evidence on the security of nicotine replacement therapy as well as the function of nicotine.

MythFact
1. Nicotine is the most dangerous ingredient in cigarettesNicotine isn’t directly in charge of tobacco-associated ailments.

The sole significant activities of nicotine in cigarettes are the

induction as well as upkeep of dependence.

Nicotine doesn’t cause respiratory diseases, isn’t carcinogenic and isn’t a significant reason for cardiac risk related to smoking.

2. Nicotine causes cancerNicotine isn’t carcinogenic.

There isn’t any clinical evidence that NRT is related to a higher danger of developing cancer.

3. Cardiovascular disease is caused by nicotineNicotine has hemodynamic effects nevertheless it isn’t the major reason for increased cardiac risk related to smoking.

NRT can be utilized in patients with stable cardiac ailments, including angina and previous myocardial infarction as a cessation support.

4. Smoking while raises the danger of heart attack and is dangerous.Smoking whilst using nicotine replacement therapy doesn’t raise the chance of a heart attack or associated cardiovascular events as fortitude to the hemodynamic effects of nicotine grows intensely.
5. Using multiple type of nicotine replacement is dangerousMixing multiple type of NRT may be used to help individuals stop smoking.

When more than one type of NRT is used in appropriate smokers clinical trials have shown no significant upsurge in adverse events.

6. Nicotine replacement therapy is as addictive as cigarettesAs it’s produced fast from smoke nicotine from cigarettes is addictive. All types of NRT have no or low exploitation potential and provide nicotine.
7. Nicotine replacement therapy is at least as dangerous as smoking during pregnancyNRT has the capacity to boost birth outcomes and is safer than continuing smoking during pregnancy.
8. While breastfeeding, nicotine replacement therapy is at least as dangerous as smokingUsing NRT while breastfeeding is safer than continuing smoking as it reduces baby exposure to cigarette smoke and is not likely to be dangerous

 

9. Nicotine replacement therapy isn’t safe to be used by youth smokersouth smokers can safely us NRT to assist them stop.

The adverse event profile of NRT in teens is just like in adults.

Youth smokers should consider as a cessation assistance NRT who are inspired to stop and that are daily smokers.

Myth 1:

Nicotine is the most dangerous ingredient in cigarettes.
Fact: Cigarette smoke contains over 4000 compounds also it’s these toxins that are other, not nicotine, which are in charge of tobacco-associated ailments.

Smoking tobacco is the leading cause of death and preventable disease . Smoking damages nearly every organ within the body, causing many disorders including cardiovascular disease, chronic respiratory illnesses, and many cancers.
The main actions of nicotine in cigarettes is the care of dependence.
It’s the multitude of other toxins in cigarette smoke which might be in charge of many damaging effects of smoking. Nicotine is not demonstrated to be carcinogenic.
It is not implicated in the evolution of chronic respiratory diseases.
It isn’t a significant cardiac risk factor although nicotine has hemodynamic effects which could play some part in raising the threat of cardiovascular disease.
Using nicotine replacement therapy (NRT) isn’t connected with increase danger of cardiovascular events.

Myth 2:

Nicotine causes cancer.
Fact: Nicotine isn’t carcinogenic. There isn’t any clinical evidence that NRT is related to a higher danger of developing cancer.

Smoking tobacco is a top source of cancer. Tobacco smoke contains more than 50 known carcinogens including nitrosamines. There’s substantial evidence that many human cancers are caused by nitrosamines. Nicotine is not demonstrated to be carcinogenic in animals and also to date there isn’t any evidence that NRT causes cancer in people. Nicotine could bring about a heightened cancer risk via metabolism or by encouraging tumour growth, yet it seems extremely unlikely that nicotine is really capable of provoking cancer under standard conditions.

Signs supporting the long-term security of nicotine comes from epidemiological studies of Swedish snus use, an oral smokeless tobacco merchandise. These studies found no increased danger of kidney cancer, oral cancer, gastric cancer, lung cancer or head and neck cancers. One study of snus use has found a heightened threat of pancreatic cancer, yet the authors credited this excess risk to nitrosamine not and content nicotine.

Myth 3:

Nicotine causes cardiovascular disease (e.g. myocardial infarcts and strokes).
Fact: Smoking is a leading reason for strokes and cardiovascular disease. Nicotine has hemodynamic effects nevertheless it’s not the major reason behind increased cardiac risk. NRT is safe to make use of including previous myocardial infarction and angina in patients with stable cardiac circumstances, as a cessation support.

Smoking is a leading reason for strokes and cardiovascular disease. Nicotine has pharmacological influences on the cardiovascular system leading to blood pressure and increased heartbeat plus coronary artery vasoconstriction can be caused by it. Yet smoke smoking is dangerous as, unlike smoking, nicotine result in arterial disease or alone doesn’t lower oxygen carrying capacity, activate coagulation.

The security of NRT in patients with cardiovascular disease is well supported by evidence from meta- evaluation, clinical trials, observational and physiological studies. The signs is the fact that NRT isn’t related to a heightened danger of adverse cardiovascular consequences or myocardial infarct. Cardiovascular risk factors enhance complete with that’s carried through with NRT, and NRT seems safe when combined with high doses of transdermal patch, whilst continuing smoking or mix NRT.

NRT hasn’t been well examined in patients and acutely ill cardiac patients with cardiac ailments that were unstable. The studies which have been done haven’t demonstrated a growth in risk of vascular events. Lower degrees of nicotine with NRT and the slower delivery speeds indicate that NRT is safer than continuing smoking in these types of patients.

Myth 4:

Smoking while using raises the threat of heart attack and nicotine replacement therapy is dangerous.
Fact: Smoking whilst the danger will not substantially boost
Of a heart attack or cardiovascular events that are associated.

It’s suggested that individuals using NRT quit smoking while using NRT to minimize the possibility of adverse events related to high doses including vomiting and nausea, in addition to to boost the speed of successful stopping rather than any particular cardiovascular risk.

Smoking whilst doesn’t present a substantial added cardiovascular risk than that posed by smoking. Physiological studies, including one study of wearing up to three 21mg nicotine patches whilst smoking, have shown that endurance develops intensely to the hemodynamic aftereffects of nicotine, such that additional increases in nicotine concentrations from the usage of NRT will not further increase heartbeat, blood pressure or another cardiovascular effects when compared with smoking alone.

Myth 5:

Using multiple type of nicotine replacement is dangerous.
Fact: Mixing multiple type of NRT can be utilized safely to help individuals during a stop smoking effort.

You will find merely a few clinical trials of the combined use of greater than one type of NRT. These clinical trials show that combination treatment may be far better than one type of NRT. These trials haven’t demonstrated any substantial escalation in adverse events to indicate this practice is dangerous.

Myth 6:

Nicotine replacement therapy is as addictive as cigarettes.
Fact: Nicotine replacement therapy has a low abuse potential. Nicotine patches have minimal possibility that is addictive and oral forms of NRT are less addictive than cigarettes.

Nicotine may be quite addictive using its addictive potential changing in line with the speed and route of administration. Inhalation of nicotine through smokes is the most addictive approach to nicotine delivery as:
It takes just 10-19 seconds for the nicotine absorbed in the lungs to reach the brain.
This routine is replicated and then drop quickly; and • Peak blood nicotine levels are reached within seconds and augmented with each inhalation.

As got from smoking, nicotine replacement therapy doesn’t create the high-speed, elevated degrees of nicotine. The increase in blood nicotine levels is slower as well as the amount of change is fell. Oral types of NRT, e.g. chewing gum, deliver nicotine at a speed more rapid than transdermal patch but considerably slower than from a smoke. Nicotine gum and lozenges have a low addictive potential even though it’s for NRT patches which has virtually no addictive potential.

Myth 7:

Nicotine replacement therapy is at least as dangerous as smoking during pregnancy
Fact: Nicotine replacement therapy has the possibility to boost birth outcomes and is safer than continuing smoking during pregnancy.

The dangerous effects of smoking during pregnancy are well-recognized and contain a heightened hazard of premature births, miscarriage and low-weight infants. Complete NRT is thought to be safer than continuing to smoke as cigarette smoke includes nicotine in addition to other known foetal toxins while nicotine may play a part with a number of the hazards to the foetus by leading to foetal ischemia, hypoxia and possibly affecting CNS progression.

Systematic reviews of smoking cessation during pregnancy have certainly shown that smoking cessation is related to improved birth outcomes including a growth in birth weight and a lowering of preterm birth.

Encounter with NRT in pregnant women is restricted. NRT use is not associated with important clinical issues for child or the mom, however its effectiveness to help stopping has also not been created. Given the requirement to safeguard the unborn infant from the proven effectiveness in the typical public as well as cigarette smoke, NRT ought to be contemplated to be used by pregnant smokers who don’t consider they’d have the capacity to stop without its help.

Myth 8:

Nicotine replacement therapy is at least as dangerous as smoking while breastfeeding.
Fact: Using nicotine replacement therapy while breastfeeding is safer than continuing smoking as it and is not likely to be dangerous reduces baby exposure.

The dangers of smoking to infants is well recorded and contains a heightened danger of neonatal mortality and sudden infant death syndrome (SIDS).

Nicotine from NRT and smoking can pass through breast milk to the baby infant exposure to nicotine is estimated to be about 50 times less than motherly exposure and is not likely to be dangerous. The utilization of NRT whilst breastfeeding could reduce infant exposure to cigarette smoke which is regarded as dangerous.

There isn’t any evidence to favor one type of NRT in preference to another for girls breastfeeding, thus the choice of which type of NRT to stop with should be according to preceding stopping expertise and patient preference.

Myth 9:

Nicotine replacement therapy just isn’t safe to be used by youth smokers.
Fact: Nicotine replacement therapy might be safely utilized by youth smokers to aid them stop.

A lot of individuals commence smoking whilst they’re teens; yet there happen to be very few studies on the best way to help youth smokers to stop.

There are merely four published studies on the usage of NRT amongst youth smokers. The info indicates that chewing gum and NRT patches are well taken by youth smokers with adverse events reported fitting those seen amongst mature smokers.

The effectiveness of NRT from these studies amongst youth smokers hasn’t been well established as a result of small size of the studies in part. Six month abstinence rates of 5% were found in both open- label trials. In a placebo controlled trial, Hanson, et al . Demonstrated that nicotine patches reduced withdrawal symptoms and cravings, yet the stop rate of 28% at 10 weeks had not been significantly different to placebo. 48 In comparison Moolchan, et al. shown higher abstinence rates for nicotine patches (17.7% vs 2.5% placebo, p=0.043), yet the abstinence rate for nicotine gum (6.5%) wasn’t statistically different to placebo. A possible secondary gain of using NRT was the decrease in how many cigarettes smoked per day amongst those youths who did not attain complete abstinence.

Given that NRT seems to be well born amongst youth smokers and the effectiveness of NRT is well established amongst mature smokers, 2, youth smokers should consider as a cessation assistance NRT who are inspired to stop and who are daily smokers.

Decision

The security profile of nicotine replacement therapy is well established as well as the evidence that is available might be summarized underneath the next statement: using nicotine replacement therapy to stop is safer than continuing to smoke. Nicotine replacement therapy is still a first- line smoking cessation treatment also contains an expanding function in helping specific patient people that are formerly considered to stop smoking.
