Nasal Spray, solution.
4.1 Therapeutic indications
Nicorette Nasal Spray is indicated for the relief of nicotine withdrawal symptoms as an aid to smoking cessation in adults and children over 12 years of age. It is also indicated in pregnant and lactating women (see section 4.6).
If possible, Nicorette Nasal Spray should be used in conjunction with a behavioural support programme.
4.2 Posology and method of administration
The patient should make every effort to stop smoking completely during treatment with Nicorette Nasal Spray.
Behavioural therapy, advice and support will normally improve the success rate.
This product must only be used with other NRT products under the advice of a healthcare professional.
This product is sprayed into the nostril when the unit is activated. If the eyes are sprayed, rinse thoroughly with water.
Directions for use
1) Remove the protective cap.
2) Prime Nicorette Nasal Spray by placing the nozzle between first and second finger with the thumb on the bottom of the bottle. Press several times firmly and quickly until a fine spray appears (up to 7–8 strokes).
Important: Point the spray safely away when priming it. Do not prime it near children or pets.
3) Insert the spray tip into one nostril, pointing the top towards the back of the nose. Press firmly and quickly. Give a spray into the other nostril.
4) Put on the protective cap
Adults (over 18 years of age)
1. The frequency of use depends on the previous smoking habit of the individual and the level of their nicotine dependence.
2. On commencing treatment the patient uses the spray to treat craving as required, subject to a limit of one spray to each nostril twice an hour.
3. A 50 ^l dose of solution is sprayed into the nostril when the unit is activated. This is described as a “spray” and dosage is described using this term. Each spray delivers 0.5 mg of nicotine, about half of which is absorbed.
4. The daily limit of use is 32mg of nicotine (64 sprays) which is the equivalent of two sprays to each nostril every hour for 16 hours.
5. The method of use of the spray should be according to the instructions.
6. The 3 month course should take the following pattern:-
a. For 8 weeks the patient uses the spray as required, subject to the maxima described above, to relieve craving.
b. After this period the patient reduces usage until after 4 more weeks treatment has ended. It is suggested that after 2 weeks into this period usage will have been reduced by a half and usage be zero by the last day. Spraying into a single nostril during this period may be helpful in achieving this.
c. Treatment should be limited to three months. The patient should understand the aim of decreasing the use of the spray to make a final break with nicotine at the end of the course, and also accept that for the first few days of the course nasal irritation may be unpleasant.
Adults who use NRT beyond 9 months are recommended to seek additional help and advice from a healthcare professional.
Adolescents (12 to 18 years)
The dose and method of use are as for adults however as data are limited in this age group, the recommended treatment duration is 12 weeks. If longer treatment is required, advice from a healthcare professional should be sought.
4.3. Contraindications
Hypersensitivity to any component of the nasal spray.
Nicorette Nasal Spray is contraindicated in children under the age of 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.
A risk-benefit assessment should be made by an appropriate healthcare professional for patients with the following conditions:
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 CVA 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 stopped and NRT is initiated as reductions in nicotine induced catecholamines release can affect carbohydrate metabolism.
GI disease: Nicotine may exacerbate symptoms in patients suffering from oesophagitis, gastritis or peptic ulcers and NRT preparations should be used with caution in these conditions. Ulcerative stomatitis has been reported.
Renal or hepatic impairment: Nicorette Nasal Spray 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.
Seizures: Potential risks and benefits of nicotine should be carefully evaluated before use in subjects with a history of epilepsy as cases of convulsions have been reported in association with nicotine.
Danger in children: Doses of nicotine tolerated by adult and adolescent smokers can produce severe toxicity in children that may be fatal. Products containing nicotine should not be left where they may be misused, handled or ingested by children.
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.
Bronchial asthma: A few cases of exacerbation of brochospasm in patients with bronchial asthma have been reported. Use of the spray in patients with hyperreactive airways is not recommended.
Excipients: This product contains methyl- and propyl- hydroxybenzoates (E217 and E218); which may cause allergic reactions (possibly delayed) and exceptionally, bronchospasm.
A clinical study confirms the safe use of this product, by smokers with chronic rhinitis and sinusitis.
Care should be taken not to spray the eyes whilst administering the spray.
4.5 Interaction with other medicinal products and other forms of interactions
No clinically relevant interactions between nicotine replacement therapy and other drugs have 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 Fertility, 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
NRT is not contraindicated in pregnancy. The decision to use NRT should be made on a risk-benefit assessment as early on in the pregnancy as possible with the aim of discontinuing use as soon as possible.
Smoking during pregnancy is associated with risks such as intra-uterine growth retardation, premature birth or stillbirth. Stopping smoking is the single most effective intervention for improving the health of both pregnant smoker and her baby. The earlier abstinence is achieved the better.
Ideally smoking cessation during pregnancy should be achieved without NRT.
Nicotine passes to the foetus and affects its breathing movements and
circulation. The effect on the circulation is dose-dependent. However for women unable to quit on their own, NRT may be recommended to assist a quit attempt.
However the risk of using NRT to the fetus 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.
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 before going to bed.
Use of nicotine by the pregnant smoker should only be initiated after advice from a health care professional.
Lactation
Nicotine should be avoided during breast-feeding. However, NRT is not contraindicated in lactation. Nicotine from smoking and NRT is found in breast milk. However the amount of nicotine the infant is exposed to is relatively small and less hazardous than the second-hand smoke they would otherwise be exposed to.
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 more easily prolonged.
Use of the nicotine by breast feeding smokers should only be initiated after advice from a health care professional. Women should take the product as soon as possible after breastfeeding.
4.7 Effects on ability to drive and use machines
The nasal spray should not be used whilst the user is driving or operating machinery as sneezing and watering eyes could contribute to accidents.
4.8 Undesirable effects
Effects of Smoking Cessation
Some symptoms may be related to nicotine withdrawal associated with stopping smoking. These can include; irritability/aggression, dysphoria/depressed mood, anxiety, restlessness, poor concentration, increased appetite/weight gain, urges to smoke (cravings), night-time awakenings/sleep disturbance,decreased heart rate, , dizziness, presyncopal symptoms, cough, constipation, gingival bleeding or nasopharyngitis.
Increased frequency of aphthous ulcer may occur after abstinence from smoking. The causality is unclear.
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 dosedependent. At recommended doses this product has not been found to cause any serious adverse effects. Excessive use of this product by those who have not been in the habit of inhaling tobacco smoke could possibly lead to nausea, faintness or headaches.
During the first 2 days of treatment, nasal irritation as sneezing, running nose, watering eyes, cough was reported by nearly all (94%) of the patients. Both the frequency and severity declined with continued use.
Allergic reactions (including symptoms of anaphylaxis) can occur during the use of this product.
The adverse reactions observed in patients treated with nicotine nasal spray 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 know (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 or search for MHRA Yellow Card in the Google Play or Apple App Store
4.9 Overdose
4.9 OverdoseSymptoms: Symptoms of overdose with nicotine from this product may occur in smokers who have previously had a low nicotine intake from cigarettes or if other sources of nicotine are used concomitantly with this product.
Acute or chronic toxicity of nicotine in man is highly dependent on mode and route of administration. Adaptation to nicotine (e.g. in smokers) is known to significantly increase tolerability compared with non-smokers. The minimum lethal dose of nicotine in a non-tolerant man has been estimated to be 40 to 60mg.
Symptoms of acute nicotine poisoning include nausea, vomiting, increased salivation, abdominal pain, diarrhoea, sweating, headache, dizziness, disturbed hearing and marked weakness. In extreme cases, these symptoms may be followed by hypotension, rapid or weak or irregular pulse, breathing difficulties, prostration, circulatory collapse and terminal convulsions.
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.
Doses of nicotine that are tolerated by adult smokers during treatment may produce severe symptoms of poisoning in children and may prove fatal. Suspected nicotine poisoning in a child should be considered a medical emergency and treated immediately.
5 PHARMACOLOGICAL PROPERTIES
5 PHARMACOLOGICAL PROPERTIES5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Drug used in nicotine dependence.
ATC code: N07B A01
Through rapid uptake of nicotine through the nasal membranes Nicorette Nasal Spray provides early relief of nicotine withdrawal symptoms. Clinical studies have shown that the nicotine containing products can help people give up smoking.
5.2 Pharmacokinetic properties
Following administration of one dose Nicorette Nasal Spray approximately 56% of the nicotine enters the systemic circulation.
The volume of distribution following i.v. administration of nicotine is approximately (2 to) 3 l/kg and the half-life ranges from 1 to 2 hours. The major eliminating organ is the liver, and average plasma clearance is about 1.2 l/min; 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.
Plasma protein binding of nicotine is <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 a significant effect on the nicotine kinetics.
The primary urinary metabolites are cotinine (15% of dose) and trans-3-hydroxycotinine (45% of the dose). Usually about 10% of nicotine is excreted unchanged in the urine. As much as 30% may be excreted in the urine with high urine flow rates and acidification below pH5.
Plasma levels of nicotine obtained with Nicorette Nasal Spray rise rapidly, reaching a maximum level – mean – after approximately 10–15 minutes. The mean peak plasma level of nicotine – after steady -state is achieved – given 1 dose/hour, 2 doses/hour and 3 doses/hour approximately 10, 19 and 28 ng/ml respectively.
After repeated administration of the Nicorette Nasal Spray the AUC was significantly higher during the last dosing interval as compared to the first giving an accumulation ratio of 3.1. No dose-dependency has been shown for the doses 0.5 mg and 1 mg nicotine.
The therapeutic blood concentrations of nicotine, (i.e. the blood levels which relieve craving) are individually based on the patient’s nicotine dependence.
