For a full list of excipients see section 6.1.
3 PHARMACEUTICAL FORM
Oromucosal spray.
A clear to weakly opalescent, colourless to light yellow solution with a scent of peppermint.
4 CLINICAL PARTICULARS
4.1 Therapeutic indications
Nicorette QuickMist 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.
Nicorette QuickMist is indicated in pregnant and lactating women making a quit attempt.
4.2 Posology and method of administration
The patient should make every effort to stop smoking completely during treatment with Nicorette QuickMist.
Behavioural therapy, advice and support will normally improve the success rate.
Directions for use
If you are using Nicorette QuickMist for the first time or if you have not used the spray for 2 days, you must first prime the spray pump.
Priming
1. Point the spray safely away from you and any other adults, children or pets that are near you.
2. Press the top of the QuickMist with your index finger 3 times until a fine spray appears.
Note: priming reduces the number of sprays you may get from Nicorette QuickMist.
After priming, point the spray nozzle as close to the open mouth as possible. Press the top of the dispenser and release one spray into your mouth, avoiding the lips. Do not inhale while spraying to avoid getting spray down your throat. For best results, do not swallow for a few seconds after spraying.
The patient should not eat or drink when administering the oromucosal spray. Care should be taken not to spray the eyes whilst administering the mouth spray.
Adults and Children over 12 years of age
Use 1 or 2 sprays when cigarettes normally would have been smoked or if cravings emerge. If after the first spray cravings are not controlled within a few minutes, a second spray should be used. If 2 sprays are required, future doses may be delivered as 2 consecutive sprays.
Most smokers will require 1-2 sprays every 30 minutes to 1 hour.
You may use up to 4 sprays per hour. Do not exceed 2 sprays per dosing episode and 64 sprays (4 sprays per hour over 16 hours) in any 24-hour period.
Each mouthspray contains at least 150 sprays.
Nicorette QuickMist should be used whenever the urge to smoke is felt or to prevent cravings in situations where these are likely to occur.
Smokers willing or able to stop smoking immediately should initially replace all their cigarettes with the Nicorette QuickMist and as soon as they are able, reduce the number sprays used until they have stopped completely.
Smokers aiming to reduce cigarettes should use the Mouthspray, as needed, between smoking episodes to prolong smoke-free intervals and with the intention to reduce smoking as much as possible.
As soon as they are ready smokers should aim to quit smoking completely.
When making a quit attempt behavioural therapy, advice and support will normally improve the success rate. Those who have quit smoking, but are having difficulty discontinuing their Mouthspray are recommended to contact their pharmacist or doctor for advice.
4.3. Contraindications
Hypersensitivity to the active substance or to any of the excipients of the mouthspray listed in section 6.1.
Nicorette QuickMist is contraindicated in children under 12 years.
4.4 Special warnings and precautions for use
Any risks that may be associated with NRT are substantially outweighed by the well established dangers of continued smoking.
Underlying cardiovascular disease: In stable cardiovascular disease this product presents a lesser hazard than continuing to smoke. However dependent smokers currently hospitalised as a result of myocardial infarction, unstable or worsening angina including Prinzmetal’s angina, severe dysrhythmia or cerebrovascular accident and who are considered to be haemodynamically unstable and/or who have uncontrolled hypertension should be encouraged to stop smoking with non-pharmacological interventions. If this fails, this product may be considered, but as data on safety in this patient group are limited, initiation should only be under medical supervision.
Diabetes mellitus: Patients with diabetes mellitus should be advised to monitor their blood sugar levels more closely than usual when smoking is stopped and NRT is initiated as reductions in nicotine induced catecholamines released by nicotine can affect carbohydrate metabolism.
GI disease: Swallowed nicotine may exacerbate symptoms in patients suffering from oesophagitis, gastritis or peptic ulcers and oral NRT preparations should be used with caution in these conditions.
Renal or hepatic impairment: This product should be used 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.
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. See Section 4.9 Overdose.
Phaeochromocytoma and uncontrolled hyperthyroidism: As nicotine causes release of catecholamines, this product should be used with caution in patients with uncontrolled hyperthyroidism or phaeochromocytoma.
Transferred dependence: Transferred dependence is rare and is both less harmful and easier to break than smoking dependence.
Stopping smoking: Polycyclic aromatic hydrocarbons in tobacco smoke induce the metabolism of drugs metabolised by CYP 1A2 (and possibly by CYP 1A1). When a smoker stops smoking, this may result in slower metabolism and a consequent rise in blood levels of such drugs. This is of potential clinical importance for products with a narrow therapeutic window, e.g. theophylline, clozapine and ropinirole.
Excipients: The mouthspray contains small amounts of ethanol (alcohol), less than 100 mg per spray.
Care should be taken not to spray the eyes whilst administering the spray.
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 i.e. increase in blood pressure and heart rate and also increase pain response (angina-pectoris type chest pain) provoked by adenosine administration.
4.6 Pregnancy and lactation
Fertility
In females tobacco smoking delays time to conception, decreases in-vitro fertilization success rates, and significantly increases the risk of infertility.
In males tobacco smoking reduces sperm production, increases oxidative stress, and DNA damage. Spermatozoa from smokers have reduced fertilizing capacity.
The specific contribution of nicotine to these effects in humans is unknown.
Pregnancy
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 used as the risk to the fetus is lower than that expected with smoking tobacco. Stopping completely is by far the best option but if this is not achievable Nicorette QuickMist may be used in pregnancy as a safer alternative to smoking. Because of the potential for nicotine-free periods, intermittent dose forms are preferable, but patches may be necessary if there is significant nausea and/or vomiting. If patches are used they should, if possible, be removed at night when the fetus would not normally be exposed to nicotine.
Lactation
The relatively small amounts of nicotine found in breast milk during NRT use are less hazardous to the infant than second-hand smoke. Intermittent dose forms would minimize the amount of nicotine in breast milk and permit feeding when levels were at their lowest.
4.7 Effects on ability to drive and use machines
Nicorette QuickMist has no or negligible influence on the ability to drive and use machines.
4.8 Undesirable effects
Effects of smoking Cessation
Some symptoms may be related to nicotine withdrawal associated with stopping smoking. These can include the following: dysphoria or depressed mood; insomnia; irritability, frustration or anger; anxiety; difficulty concentrating, restlessness or impatience; decreased heart rate; and increased appetite or weight gain. These have been observed in those using the mouthspray.
Increased frequency of aphthous ulcer, cough and nasophyringitis may occur after abstinence from smoking. The causality is unclear.
In addition to this, other cessation-associated symptoms were seen in those using the mouth spray: dizziness, presyncopal symptoms, constipation, and gingival bleeding.
Nicotine craving, which is recognised as a clinically relevant symptom, is an important element in nicotine withdrawal after smoking cessation.
Adverse Drug Reactions
This product may cause adverse reactions similar to those associated with nicotine given by other means, including smoking, and these are mainly dose-dependent.
Most adverse events reported with this product occur during the early phase of treatment and are similar to those seen with other orally delivered forms. During the first few days of treatment irritation to the mouth and throat may
be experienced and hiccups are particularly common. Tolerance is normal with continued use.
Daily collection of data from trial subjects demonstrated that very commonly occurring adverse events were reported with onset in the first 2-3 weeks of use of the spray, and declined thereafter.
Allergic reactions (including symptoms of anaphylaxis) occur rarely during use of this product.
The adverse reactions observed in patients treated with oral nicotine formulations during clinical trials and post-marketing experience are listed below by System Organ Class (SOC).
Frequencies are defined in accordance with current guidance, as: Very common (>1/10); common (>1/100, <1/10); uncommon (>1/1 000, <1/100); rare (>1/10 000, <1/1 000); very rare (<1/10 000); not known (cannot be estimated from the available data).

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.
4.9. Overdose
When used as directed, symptoms of overdose with nicotine may occur in patients with low pre-treatment nicotine intake or if other sources of nicotine are used concomitantly.
Symptoms: The minimum lethal dose of nicotine in a non-tolerant man has been estimated to be 40 to 60mg. Symptoms of overdose are those of acute nicotine poisoning and include nausea, vomiting, increased salivation, abdominal pain, diarrhoea, sweating, headache, dizziness, disturbed hearing and marked weakness. At high doses, these symptoms may be followed by hypotension, rapid or weak or irregular pulse, breathing difficulties, prostration, circulatory collapse and general convulsions.
Doses of nicotine that are tolerated by adult smokers during treatment may produce severe symptoms of poisoning in small children and may prove fatal. Suspected nicotine poisoning in a child should be considered a medical emergency and treated immediately.
Management of an overdose: All nicotine intake should stop immediately and the patient should be treated symptomatically. Artificial respiration should be instituted if necessary. Activated charcoal reduces the gastro-intestinal absorption of nicotine.
5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Drug used in nicotine dependence.
ATC code: N07B A01
Nicotine is an agonist at nicotine receptors in the peripheral and central nervous system and has pronounced CNS and cardiovascular effects.
Clinical studies have shown that nicotine replacement products can help smokers abstain from smoking by relieving these withdrawal symptoms. Compared to nicotine gum or nicotine lozenge, the absorption of nicotine from the mouth spray is more rapid (section 5.2) and based on prior experience with nicotine replacement therapy, this will result in a faster onset of relief of cravings and other symptoms.
Increased appetite is a recognised symptom of nicotine withdrawal and post-cessation weight gain is common. Clinical trials have demonstrated that Nicotine Replacement Therapy can help control weight following a quit attempt.
5.2 Pharmacokinetic properties
The pharmacokinetics of nicotine has been extensively studied, and variations in delivery format have been found to have significant effects on rate and extent of absorption.
The pharmacokinetics of the mouth spray has been studied in 4 studies. The studies included 141 subjects.
Absorption
The oral spray form means that the nicotine dose is administered instantaneously, and as a result the absorption of nicotine from the mouth spray is rapid: In trials, nicotine uptake from the oral nicotine spray was detected at 2 minutes, the first timepoint tested.
A maximum concentration of 5.3 ng/mL is reached within 13 minutes after administration of a 2 mg dose. The nicotine AUCs over the first 10 minutes after administration of the mouth spray at a dose of 1 and 2 mg exceeds those of nicotine gum as well as nicotine lozenge at doses of 4 mg (0.48 and 0.64 h*ng/mL vs. 0.33 and 0.33 h*ng/mL).
AUCoo estimates show the bioavailability of nicotine administered by mouth spray is somewhat higher than that of nicotine gum or lozenge. The AUCoo of the mouth spray 2 mg measured 18.9 h*ng/mL as compared with 16.2 h*ng/mL for nicotine gum 2 mg. Allowing for differences in administered dose, bioavailability was also higher in a second study. The nicotine AUCoo of the mouth spray 2 mg measured 14.0 h*ng/mL in comparison with 23.0 h*ng/mL and 26.7 h*ng/mL for and nicotine gum 4 mg and nicotine lozenge 4 mg, respectively.
Steady-state average nicotine plasma concentrations achieved after adminstration of the maximum dose (i.e. 2 sprays of the mouth spray 1 mg every 30 minutes) are approximately
28.8 ng/mL as compared with 23.3 ng/mL for nicotine gum 4 mg (1 gum, hourly) and 25.5 ng/mL for nicotine lozenge 4 mg (1 lozenge, hourly).
Given the rapid absorption and the similar, high relative bioavailability, the majority of the nicotine released from the mouth spray is apparently absorbed through the buccal mucosa.
Distribution
The volume of distribution following intravenous administration of nicotine is about 2 to 3 l/kg.
Plasma protein binding of nicotine is less than 5%. Therefore, changes in nicotine binding from use of concomitant drugs or alterations of plasma proteins by disease states would not be expected to have any significant effects on the nicotine pharmacokinetics.
Biotransformation
Nicotine metabolism and elimination are independent of the choice of nicotine formulation, and thus results from studies with intravenous administration of nicotine are used to describe, biotransformation and elimination.
The major nicotine-eliminating organ is the liver, although the kidney and lung also metabolise nicotine. More than 20 metabolites of nicotine have been identified, all of which are believed to be less active than the parent compound.
The primary metabolite of nicotine in plasma, cotinine, has a half-life of 15 to 20 hours and concentrations that exceed nicotine by 10-fold.
Elimination
The average plasma clearance of nicotine is 70 l/hour and the half-life is 2-3 hours.
The primary urinary metabolites are cotinine (12% of the dose) and trans-3-hydroxy-cotinine (37% of the dose). About 10% of nicotine is excreted unchanged in the urine. As much as 30% of nicotine may be excreted unchanged in the urine with high flow rates and acidification of the urine below pH 5.
Linearity/non-linearity
There is only a small deviation from dose-linearity of AUCoo and Cmax as shown when single doses of 1, 2, 3 and 4 sprays of the 1 mg mouth spray are given.
Characteristics in specific groups of subjects:
Renal Impairment
Progressive severity of renal impairment is associated with decreased total clearance of nicotine. Nicotine clearance was on average decreased by 50%, in subjects with severe renal impairment. Raised nicotine levels have been seen in smokers undergoing hemodialysis.
Hepatic Impairment
In smokers with liver cirrhosis but only mild liver impairment (Child-Pugh score 5) the pharmacokinetics of nicotine is unaffected. However, in smokers with moderately impaired liver (Child-Pugh score 7) total clearance has been reported to be reduced by 40-50%. There is no information available in subjects with a Child-Pugh score > 7.
Elderly
A minor reduction in total clearance of nicotine, not justifying adjustment of dosage, has been demonstrated in healthy elderly patients.
5.3 Preclinical safety data
Nicotine was positive in some in vitro genotoxicity tests but there are also negative results with the same test systems. Nicotine was negative in in vivo tests.
Animal experiments have shown that nicotine exposure results in decreased birth-weight decreased litter size and decreased survival of offspring.
The results of carcinogenicity assays did not provide any clear evidence of a tumorigenic effect of nicotine.
