Prescribing medication, health care providers can even help you to quit tobacco use and the quit smoking. These are medicines that are don’t contain nicotine and are not habit forming. It functions differently from nicotine patches, sprays, gums and lozenges. Medicines for smoking cessation can help with elimination of tobacco as well as the withdrawal symptoms. It can also stop you from starting to smoke again. These anti-smoking medicines work best when they are an important program part. This includes making a clear decision to quit and setting the quit date. Creating plans that help in dealing with smoking cravings are also crucial. Finally, getting support from a doctor, support group or counselor is important. Close to 46.5 million Americans smoke. Of these, 70% want to quit immediately and every year, close to 17 million adults in the US made a serious attempt to quit. Following a meta analysis of more than 6 thousand published articles, research has isolated two treatment related themes:
Firstly, the use of cessation medication approved for this purpose increases the chances of quitting by more than twice.
Second, the effects of medication for cessation are increased when coupled with behavioral intervention.
Many prescription drugs have been shown to help smokers to quit. While some can be used with nicotine replacement therapy, you need to take them before the day of quitting. Smokers significantly dependent on nicotine need to consider NRT or drug therapy to enable them to quit. You know you need medical help them you are displaying the following signs and symptoms:
- Smoking more than a single pack a day.
- Smoking within just 5 minutes of waking up.
- Smoking while sick.
- Getting up at night to smoke
- Smoking to ease withdrawal symptoms
For more serious smokers, the dependence can be severe. Regarding meta analysis of research trials, assessing when cessation was effective, it was found when medical professionals provided advice associated with there was cessation, increased likelihood of quitting as opposed to no advice, with odds ratio of 1.7. Complex and long drawn out advice led to higher quit rates than those associated with minimal advice, with odds ratio at 1.4. Physicians are also in a position to identify tobacco users and enable patients to quit and routinely ask patients regarding tobacco use, strongly advising tobacco users to quit. Additionally, it helped when the readiness of smokers to quit and assist patients with quitting as well as arrange counseling post the follow-up.
A US Public Health Service Guideline for Clinical Practice indicates when it is possible and there is no medical contraindications, tobacco cessation interventions should include one FDA approved pharmaceutical aid along with counseling for tobacco dependence. Here are the anti smoking aids or smoking cessation medications that can be used.
First Line Agent: NRTs
Five agents have been approved by the Food and Drug Administration for cessation of smoking. There are 4 nicotine replacement preparations namely nicotine nasal spray, inhaler, patches and gum. Additionally, there is sustained release bupropion hydrochloride too. First line medication includes NRT or Nicotine Replacement Therapy. Additionally NRT therapy promotes quitting through reduction of withdrawal symptoms of nicotine. This permits patients to focus on psychological and behavioral aspects of smoking. Along with this, the onset of NRT action is not as quick as nicotine obtained through smoking.
Additionally, NRT should be tried with care along with patients with underlying cardiac arrhythmia. Additionally, there is serious or steadily advancing angina pectoris pain and those with recent myocardial-infarction. This is on account of nicotine causing adverse cardiovascular impact by raising the myocardial strain through rising blood pressure and heart rate. Nicotine constricts coronary arteries, causing problems like cardiac ischemia. The risk of NRT for clients with cardiovascular conditions are lower as against risk of persistent smoking.
As per the FDA, nicotine is a substance that can harm the human fetus. Consequently, none of these NRT formulations have been FDA approved for usage in pregnancy. While NRT may create a risk for the growing fetus, it is lower than the risk of persistent smoking. NRT is only reserved for women who cannot quit using non medicinal means. Doses need to be at the lower end of the range and formulations yielding intermittent rather than persistent drug exposure are responsible. Nasal spray, inhaler and gum are some of the options.
Medicines can lead to smoking cessation, if used correctly. NRT contains decreasing increments of nicotine to lower chances of headache and irritability as one quits smoking. Non nicotine prescription medications can also reduce the severity of nicotine medication. Using NRT in combination with non nicotine drugs may work for you too. Study how to take the medicines best under medical supervision and consult your doctor or nurse before opting for smoking cessation.
Nicotine replacement medications are a good form of therapy, but under no conditions must nicotine be paired with a cigarette. Smoking must cease when you use nicotine replacement therapy. NRT lasts from 2-3 months. Though one can buy many products without a prescription,check with the doctor about which medicine works best for you.
Nicotine polacrilex gum is available without prescription. It refers to a resin complex of nicotine and polacrilin in a chewing gum base which is sugar-free. Buffering agents like sodium biocarbonate and sodium carbonate raise saliva pH value, enhancing nicotine absorption across the buccal mucosa. Patients need to use gums on a schedule that is fixed rather than controlling cravings. This product tends to stick to dental work and is not suited for patients, who have dental implants, braces, bridges and dentures or even dental restorations.
Nicotine gum enhances cessation of smoking by 50 percent as opposed to interventions that are controlled. This is ideal for those who want something to chew on as they quit smoking. Studying boredom as a factor influencing smoking points the way to the effectively quitting this habit.
A nicotine patch that is trans-dermal is available sans or with prescription both. It works through concentration linked, continuous low level nicotine delivery across the skin. There are 4 formulations currently available and dosing is associated with cigarettes smoked in a day. The sixteen and 24-hour patches demonstrate a lot of efficiency. But there can also be sleep disturbances arising out of patch related use. This includes vivid, abnormal dreams or lack of sleep. So, for these patients, the 16 hour patch may be a better one. Patients with stronger cravings at dawn may benefit from a 24-hour patch. Those who have substantial withdrawal, cravings or symptoms should consider a dose that is higher. Those with adverse effects such as dizziness, nausea, perspiration, vomiting, headache, diarrhea and ab pain. Reactions to adhesives associated with the patch are common leading up to 50% and can be treated with 1% hydro-cortisone cream or oil histamines. Adhesives vary across products and those with allergies and skin reactions can switch brands. Those with dermatological medical conditions like eczema, atopic dermatitis and psoriasis can suffer from skin irritation and other nicotine replacement therapy formulations.
Using the nicotine patch, cessation rates in patients is 1.9 times more than that seen in patients with placebo. Trans-dermal formulas are only dosed once a day, making it ideal for low compliance cases. A prescription is not needed to buy a nicotine patch. The patches may come in different strengths ranging across 5, 10, 15, 7, 14 and 21 mg strength. The strength you need to use should be assessed depending on the amount smoked. Tapering down the patches on recommended schedule is needed. The patch can be placed on the chest or the arm. You need to put on a patch between sixteen and twenty four hours. If there is trouble sleeping or one has disturbing dreams, the patch should be removed when one goes to sleep and a new one should be used on getting up at dawn. Side effects include soreness and redness under the patch. For lowering side effects,the location of the patch should be changed each day.
This spray is an aqueous solution for nasal delivery. There are around 0.5 mg bolus of nicotine delivered through each actuation absorbed super fast in less than 10 minutes across the nasal mucosa. At the start, many patients have throat and nose irritation such as peppery sensation, watering in the eyes, coughing and sneezing. With the rise of regular use, tolerance gradually develops and post the first week, the ability to bear the sprays increases. The spray is not suited for those with chronic nasal disorders such as sinusitis, rhinitis and polyps or patients facing severe reactive disease of the airways on account of the irritant effects of the spray. Drug absorption can be reduced in those who have rhinitis or a cold.
Cessation rates linked with nicotine nasal spray range across 1.8 to 4.1 times more than in controls. On account of rapid action onset, the spray is suited for those who prefer medication for managing withdrawal symptoms.
Nicotine inhalation comprises a plastic mouthpiece and unit dose cartridge delivering around 4 mg of inhaled nicotine with a mild menthol taste from a plug which is porous. Post the inhalation, vaporization of nicotine takes place and it is absorbed through the medium of the oropharyngeal mucosa. Nicotine inhalers are not like oral inhalers used for curing pulmonary medical conditions. The drug does not get inhaled deeply in the lungs because there is rising incidence of adverse effects and increase in nicotine delivery. There may also be mild irritation of the mouth or throat, rhinitis, cough or aggravated effects which decrease with the product use much like smoking.
Nicotine gums are not the only OTC therapy available. One can buy gums or lozenges in a drug store without prescription. Instructions can be read and these lozenges can serve as the perfect means of quitting. Not more than twenty pieces per day is allowed if one uses a 4 mg gum or lozenge or 30 pieces per day if you use a 2 mg gum or lozenge. The number of pieces employed decrease across time. Another important consideration is that coffee, cola juice or alcohol or orange juice just 15 minutes before using lozenges. These drinks can make nicotine replacement less easy to handle. Side effects like throat and mouth discomfort can result if lozenges are not used correctly. Lozenges can only be used for three months.
Bupropion Sustained Release
In the late 90s, sustained-release bupropion was approved as the leading non NRT medication for cessation of smoking. This product was earlier categorized as an antidepressant is known for its ability to block reuptake of neurotransmitters norepinephrine and dopamine. This further prevents nicotine cravings and withdrawal.This therapy needs to be started a couple of weeks before the date for quitting, starting with 150mg per day for 2 days. This increases to 150 mg twice in a day. Mediation commences prior to quit date, as therapeutic levels are reached post 7 days of therapy.
Adverse factors associated with bupropion therapy include dry mouth and insomnia. These lessen with persistent use. Additionally, the second dose in early evening 8 hours post the first dose can prevent insomnia. Less common effects of this non nicotine medicine include rash and tremors. As seizures are possible in 1 of 1000 patients looking to quit smoking, bupropion is not allowed in those with history of seizures or problems like anorexia and bulimia or central nervous system tumors and constant use of medications to lower the threshold of seizures. As the seizures are pertaining to doses, the dosage needs to be spaced 8 hours apart and total dose daily should not increase 300 mg. Research indicates that this drug can be used along with NRT effectively. Pregnancy category B is its classification and use should be considered only when non medical methods are not working.
Additionally, quitting rates in patients opting for this medicine is 2.1 times more than patients who had a placebo. The benefits of bupropion include oral formulation with a twice a day dosing, no chance of nicotine toxicity and in case the patient persists in smoking, it can be used along with NRT and benefits those with co-morbid conditions like depression.
Second Line of Attack: Secondary Agents
Though many of these medicines are not FDA approved for smoking cessation, they can be used as second line agents. This includes prescription medicines like clonidine hydrochloride and nortriptyline hydrochloride. Clonidine is a centrally acting α2 drug which means it acts as an agonist antihypertensive and doubles cessation or quitting rates. Initially, doses recommended include 0.1 mg orally two times in a day or 0.1 mg per dat patch applied on a weekly basis. Efficient doses range around 0.15 to 0.75 mg everyday for twelve weeks orally. Around 0.1 to 0.2 mg is taken through the trans-dermal route for three to ten weeks. The quitting probability increases by three times with the action of the tricyclic antidepressant agent, as against a placebo. The recommended starting dose is 25 mg at bedtime, increasing to target dose of 75-100 mg everyday for 12 weeks. Absence of FDA approval for smoking cessation as well as undesirable side effects are the reason why this is a second line of attack.
Combination Therapy and High Dose NRT
Most clinical trials use a single agent, while some investigators report enhanced cessation rates when bodies are used in combination. Evidence indicates that persistent and concurrent use of two NRT forms is beneficial. This is because just as the first one provides steady nicotine levels in the body and the second form is needed to control cravings, suppressing nicotine withdrawal and increasing the chances of quitting, as compared to single therapies. Use of dual NRT is recommended in case patients who cannot use monotherapy quit due to inherent risk of an overdose of nicotine. The use of bupropion in conjunction with the patch was associated with better outcomes than the bupropion alone. Some research also suggests that higher doses of NRT will be effective for heavy smokers.
Smoking and the Use of Medicines
Tobacco use is the prime cause of morbidity and mortality in the US. Close to 430,000 deaths result from smoking annually. On account of the fact that tobacco based diseases are preventable, if smoking is stopped using first line medication, cessation can be initiated for the long term. Selecting the line of attack to counter smoking should be tailored for every patient. Factors to consider include medication compliance issues, patent preference. previous cessation agent experiences and patient characteristics.
This includes factors like contraindications, depression and medical history and extent of smoking. Pharmacological therapy needs to be accompanied by behavioral counseling to enhance rates for long term cessation. Most smoking cessation medications come with generic as well as trade names. The aim is to be clear about what you are taking. Do remember that your doctor and pharmacist are your best sources of information. Discuss the drugs with your medical practitioner and understand desired effects as well as side effects. Don’t stop or change the frequency of medication without a medical consultation.
