NiQuitin Pre-Quit Clear 21 mg Patch

2 QUALITATIVE AND QUANTITATIVE COMPOSITION

NiQuitin Clear is a transdermal delivery system for topical application available in systems of 22 cm2 containing 114 mg nicotine, equivalent to 5.1 mg/cm2 of nicotine and delivering 21 mg over 24 hours.

For the full list of excipients, see section 6.1.

Transdermal patch.

4.1 Therapeutic indications

NiQuitin Clear relieves and/or prevents craving and nicotine withdrawal symptoms associated with tobacco dependence. It is indicated to aid smokers wishing to quit or reduce prior to quitting, to assist smokers who are unwilling or unable to smoke, and as a safer alternative to smoking for smokers and those around them.

NiQuitin Clear is indicated in pregnant and lactating women making a quit attempt.

If possible, when stopping smoking, NiQuitin Clear should be used in conjunction with a behavioural support programme.

4.2

Posology and method of administration

NiQuitin Clear patches should be applied once a day, at the same time each day and preferably soon after waking, to a different non-hairy, clean, dry skin site and worn continuously for 24 hours. The NiQuitin Clear patch should be applied promptly on removal from its protective sachet. It should be pressed firmly on the skin with the palm of hand for 10 seconds. Areas where the skin creases should be avoided.

Avoid applying to any skin which is broken, red or irritated. After 24 hours the used patch should be removed and a new patch applied to a fresh skin site. The patch should not be left on for longer than 24 hours. Skin sites should not be reused for at least seven days. Only one patch should be worn at a time.

The patch should be kept sealed in its protective sachet until ready to use. The user should wash hands with water after handling the patch, and avoid contact with eyes and nose.

Patches may be removed before going to bed if desired. However use for 24 hours is recommended to optimise the effect against morning cravings.

Water will not harm the nicotine transdermal patch, if it has been applied properly. The user can bathe, swim or shower for short periods while wearing the nicotine transdermal patch.

Concurrent behavioural support is recommended, as such programmes have been shown to be beneficial for smoking cessation.

Adults (18 years and over)

Abrupt cessation of smoking:

During a quit attempt every effort should be made to stop smoking with NiQuitin Clear.

NiQuitin Clear therapy should usually begin with NiQuitin Clear 21 mg Patch and be reduced according to the following dosing schedule:-

Dose                         ­Duration

Step 1

NiQuitin Clear 21 mg Patch First 6 weeks

Step 2 NiQuitin Clear 14 mg Patch Next 2 weeks

Step 3 NiQuitin Clear 7 mg Patch Last 2 weeks

Light smokers (e.g. those who smoke less than 10 cigarettes per day) are recommended to start at Step 2 (14 mg) for 6 weeks and decrease the dose to NiQuitin Clear 7 mg Patch for the final 2 weeks.

Patients on NiQuitin Clear 21 mg Patch who experience excessive sideeffects (please refer to precautions), which do not resolve within a few days, should change to NiQuitin Clear 14mg Patch. This strength should then be continued for the remainder of the 6 week course before stepping down to NiQuitin Clear 7mg Patch for two weeks. If the symptoms persist the patient should be advised to seek the advice of a healthcare professional.

For optimum results, the 10 week treatment course (8 weeks for light smokers or patients who have reduced strength as above), should be completed in full. Treatment with NiQuitin Clear patch may be continued beyond 10 weeks if you need it to stay cigarette free, however those who have quit smoking but have difficulty discontinuing using the patches are recommended to seek additional help and advice from a healthcare professional.

Further courses may be used at a later time, for NiQuitin Clear patch users who continue or resume smoking.

Gradual Cessation:

For smokers who are unwilling or unable to quit abruptly.

The 21 mg patch can be used daily for 2–4 weeks while the user continues to smoke as needed. At the end of the 2–4 weeks the user should quit completely and continue using Step 1 21 mg patch for 6 weeks daily without smoking. Thereafter following the Step 2 and 3 directions for abrupt cessation above. Should the patient feel able to quit completely before their designated quit date they can do so.

Reduction in smoking:

For smokers who wish to cut down with no immediate plans to quit.

A patch can be used while the user continues to smoke as needed. The user should reduce the number of cigarettes smoked as far as possible and to refrain from smoking as long as possible. Users should be encouraged to stop smoking completely as soon as possible.

If users are still feeling the need to use the patches on a regular basis 6 months after the start of treatment and have still been unable to undertake a permanent quit attempt, then it is recommended to seek additional help and advice from a healthcare professional.

Temporary Abstinence

Apply a patch to control troublesome withdrawal symptoms including craving during the period when smoking is being avoided. Users should be encouraged to stop smoking completely as soon as possible.

If users are still feeling the need to use the patches on a regular basis 6 months after the start of treatment and have still been unable to undertake a permanent quit attempt, then it is recommended to seek additional help and advice from a healthcare professional.

Adolescents (12 to 17 years) should follow the schedule of treatment for abrupt cessation of smoking as given above. Where adolescents are not ready or not able to stop smoking abruptly, advice from a healthcare professional should be sought.

Safety and effectiveness in children who smoke has not been evaluated. NiQuitin Clear is not recommended for use in children under 12 years of age.

4.3 Contraindi­cations

NiQuitin Clear is contraindicated in patients with hypersensitivity to the system, the active substance, or any of the excipients.

NiQuitin Clear patches should not be used by non-smokers, occasional smokers or children under 12.

4.4 Special warnings and precautions for use

The risks associated with the use of NRT are substantially outweighed in virtually all circumstances by the well established dangers of continued smoking.

Patients hospitalised for MI, severe dysrhythmia or CVA who are considered to be haemodynamically unstable should be encouraged to stop smoking with non-pharmacological interventions. If this fails, NiQuitin Clear patches may be considered, but as data on safety in this patient group are limited, initiation should only be under medical supervision. Once patients are discharged from hospital they can use NRT as normal. If there is a clinically significant increase in cardiovascular or other effects attributable to nicotine, the nicotine patch dose should be reduced or discontinued.

Nicotine replacement therapy may exacerbate symptoms in persons suffering from active oesophagitis, oral and pharyngeal inflammation, gastritis, gastric ulcer or peptic ulcer.

Diabetes: Blood glucose levels may be more variable when stopping smoking, with or without NRT as catecholamines released by nicotine can affect carbohydrate metabolism so it is important for diabetic to monitor their blood glucose levels more closely than usual while using this product.

Allergic reactions: Susceptibility to angioedema and urticaria.

Atopic or eczematous dermatitis (due to localised patch sensitivity): In the case of severe or persistent local reactions at the site of application (e.g. severe erythema, pruritus or oedema) or a generalised skin reaction (e.g. urticaria, hives or generalised skin rashes), users should be instructed to discontinue use of NiQuitin Clear and contact their physician.

Contact sensitisation: Patients with contact sensitisation should be cautioned that a serious reaction could occur from exposure to other nicotine-containing products or smoking.

A risk benefit assessment should be made by an appropriate healthcare professional for patients with the following conditions:

Renal and hepatic impairment: Use with caution in patients with moderate to severe hepatic impairment and/or severe renal impairment as the clearance of nicotine or its metabolites may be decreased with the potential for increased adverse effects.

Phaeochromocytoma and uncontrolled hyperthyroidism: Use with caution in patients with uncontrolled hyperthyroidism or phaeochromocytoma as nicotine causes release of catecholamines.

Seizures: Potential risks and benefits of nicotine should be carefully evaluated before use in subjects taking anti-convulsant therapy or with a history of epilepsy as cases of convulsions have been reported in association with nicotine.

Cardiovascular disease: The pre-cessation regimen should not be used in people with known cardiovascular disease without evaluation of the risk/benefit by a healthcare professional.

Danger in small children: Doses of nicotine tolerated by adult and adolescent smokers can produce severe toxicity in small children that may be fatal. Products containing nicotine should not be left where they may be misused, handled or ingested by children. After removal, the patch should be folded in half, adhesive side innermost, and placed inside the opened sachet, or in a piece of aluminum foil. The used patch should then be disposed of with care.

Patches should be kept out of the sight and reach of children.

Stopping smoking: Polycyclic aromatic hydrocarbons in tobacco smoke induce the metabolism of drugs catalysed by CYP 1A2 (and possibly by CYP 1A1). When a smoker stops this may result in a slower metabolism and a consequent rise in blood levels of such drugs.

Transferred dependence: Transferred dependence is rare and is both less harmful and easier to break than smoking dependence.

Safety on handling: NiQuitin Clear is potentially a dermal irritant and can cause contact sensitisation. Care should be taken during handling and in particular contact with the eyes and nose avoided. After handling, wash hands with water alone as soap may increase nicotine absorption.

Users who initiate quitting with pre-cessation NRT and experience exaggerated effects as listed in ‘overdose’ (see section 4.9) should discontinue smoking and if the symptoms persist remove the patch. If symptoms improve after smoking cessation, the user may resume using the patch.

4.5 Interaction with other medicinal products and other forms of interaction No clinically relevant interactions between nicotine replacement therapy and other drugs has definitely been established, however nicotine may possibly enhance the haemodynamic effects of adenosine.

Healthcare professionals are reminded that smoking cessation itself may require the adjustment of some drug therapy.

4.6 Fertility, pregnancy and lactation

Smoking during pregnancy is associated with risks as intra-uterine growth retardation, premature birth or stillbirth. Stopping smoking is the single most effective intervention for improving the health of both the pregnant smoker and her baby, and the earlier abstinence is achieved the better. Ideally smoking cessation during pregnancy should be achieved without NRT. However, if the mother cannot (or is considered unlikely to) quit without pharmacological support, NRT may be recommended by a healthcare professional to assist a quit attempt.

The risk of using NRT to the foetus is lower than that expected with tobacco smoking, due to lower maximal plasma nicotine concentration and no additional exposure to polycyclic hydrocarbons and carbon monoxide.

However, as nicotine passes to the foetus affecting breathing movements and has a dose dependent effect on placental/foetal circulation, the decision to use NRT should be made as early on in the pregnancy as possible. The aim should be to use NRT for only 2–3 months.

Intermittent dosing products may be preferable as these usually provide a lower daily dose of nicotine than patches. However, patches may be preferred if the woman is suffering from nausea during pregnancy. If patches are used, they should be removed at night before going to bed when the foetus would not normally be exposed to nicotine.

Nicotine from smoking and NRT is found in breast milk. However, the amount of nicotine the infant is exposed to from NRT is relatively small and less hazardous than the second-hand smoke they would otherwise be exposed to.

Ideally smoking cessation during lactation should be achieved without NRT. However for women unable to quit on their own, NRT may be recommended by healthcare professional to assist a quit attempt.

Using intermittent dose NRT preparations, compared with patches, may minimize the amount of nicotine in the breast milk as the time between administrations of NRT and feeding can be made as long as possible. Women should try to breastfeed just before they take the product.

Effects of nicotine on male reproductive tissues have been observed in rats (see section 5.3), however the clinical significance is unknown.

4.7 Effects on ability to drive and use machines

NiQuitin Clear Patches have no or negligible influence on the ability to drive and use machines. However, users of nicotine replacement products should be aware that smoking cessation can cause behavioural changes.

4.8 Undesirable effects

NRT may cause adverse reactions similar to those associated with nicotine administered by other means, including smoking. These may be attributable to the pharmacological effects of nicotine, some of which are dose dependent. At recommended doses NiQuitin Clear patches have not been found to cause any serious adverse effects. Excessive use of NiQuitin Clear patches by those who have not been in the habit of inhaling tobacco smoke could possibly lead to nausea, faintness or headaches.

Subjects quitting smoking by any means could expect to suffer from asthenia, headache, dizziness, sleep disturbance, coughing or influenza-like illness. Certain symptoms which have been reported such as depression, irritability, nervousness, restlessness, mood lability, anxiety, drowsiness, impaired concentration and insomnia may be related to withdrawal symptoms associated with smoking cessation.

The following undesirable effects have been reported in clinical trials or spontaneously post-marketing.

Uncommon >1/1000; <1/100: hypersensitivity NOS*

Very rare <1/10000: anaphylactic reactions

Very rare >1/100000; <1/10000: dermatitis allergic*, dermatitis contact*, photosensitivity

Common >1/100; <1/10: arthralgia, myalgia

5   PHARMACOLOGICAL PROPERTIES

Following removal of NiQuitin Clear, plasma nicotine concentrations decline with an apparent mean half-life of 3 hours, compared with 2 hours for IV administration due to continued absorption of nicotine from the skin depot. If NiQuitin Clear is removed most non-smoking patients will have non-detectable nicotine concentrations in 10 to 12 hours.

A dose of radio-labelled nicotine given intravenously showed a distribution of radioactivity corresponding to the blood supply with no organ selectively taking up nicotine. The volume of distribution of nicotine is approximately 2.5 l/kg.

The major elimination organ is the liver and average plasma clearance is about 1.2 l/min; the kidney and the lung also metabolise nicotine. More than 20 metabolites of nicotine have been identified, all of which are believed to be pharmacologically inactive. The principal metabolites are cotinine and trans-3-hydroxycotinine. Steady state plasma cotinine concentrations exceed nicotine by 10-fold. The half-life of nicotine ranges from 1 to 2 hours and cotinine’s between 15 and 20 hours.

Both nicotine and its metabolites are excreted through the kidneys and about 10% of nicotine is excreted unchanged in the urine. As much as 30% may be excreted in the urine with maximum flow rates and extreme urine acidification (pH<5).

There were no differences in nicotine kinetics between men and women using nicotine patches. Obese men using nicotine patch had significantly lower AUC and Cmax values compared with normal weight men. Linear regression of AUC vs total body weight showed the expected inverse relationship (AUC decreases as weight increases). Nicotine kinetics were similar for all sites of application on the upper body and upper outer arm.

5.3 Preclinical safety data

The general toxicity of nicotine is well known and taken into account in the recommended posology. Nicotine was not mutagenic in appropriate assays. The results of carcinogenicity assays did not provide any clear evidence of a tumorigenic effect of nicotine. In studies in pregnant animals, nicotine showed maternal toxicity, and consequential mild fetal toxicity. Additional effects included pre- and postnatal growth retardation and delays and changes in postnatal CNS development.

Studies in male rats have shown that nicotine can decrease testis weight, cause a reversible decrease in Sertoli cell numbers with impairment of spermatogenesis, and result in a variety of changes in the epididymis and vas deferens. However, similar effects have not been reported to occur in humans.

Effects were only noted following exposure to nicotine at levels in excess of those which will result from recommended use of NiQuitin Clear.

Comparison of the systemic exposure necessary to elicit these adverse responses from preclinical test systems with that associated with the recommended use of NiQuitin Clear indicate that the potential risk is low and outweighed by the demonstrable benefit of nicotine therapy in smoking cessation. However, NiQuitin Clear should only be used by pregnant women on medical advice if other forms of treatment have failed.
