3 PHARMACEUTICAL FORM
Solution for injection
The solution is a dear, not opalescent, colourless liquid with a pH value of 3.6 to 4.4.
4 CLINICAL PARTICULARS
4.1 Therapeutic indications
Local anaesthesia (infiltration and nerve-block anaesthesia) in dentistry.
This medicine is indicated in adults, adolescents and children aged more than 4 years.
4.2 Posology and method of administration
This medicine is exclusively recommended for use in dentistry. Posology
The smallest possible volume of solution which will lead to an effective anaesthesia should be used.
Adults:
The dosage should be individually determined from case to case depending on the method used and special characteristics of the particular case.
In oral infiltration and/or mandibular block, initial dosages of 1.0-4.0 ml are usually sufficient.
Special populations:
Elderly population: Increased plasma levels of this medicine can occur in older patients due to diminished metabolic processes and reduced distribution volume. The risk of accumulation of Xylestesin with Adrenaline is increased after repeated administration in particular.
Dosages should be reduced from adult recommendations, taking into consideration any cardiac or liver disease (see section 4.4).
Patients with hepatic Impairment: Lidocaine is metabolized by the liver. Lower doses of lidocaine may be required in patients with hepatic dysfunction due to prolonged effects and systemic accumulation (see section 4.4).
Patients with renal Impairment: Lidocaine and its metabolites are mainly eliminated in urine. Lower doses of lidocaine may be required in patients with severe renal dysfunction due to prolonged effects and systemic accumulation (see section 4.4).
Other relevant special populations: The dose has to be likewise reduced in patients with certain pre-existing diseases (angina pectoris, arteriosclerosis, see section 4.3 and 4.4) and patients taking contemporary medications known to interact with lidocaine and/or see section 4.4 and 4.5).
Dose recommendation for special populations: A lower dosage range is thus recommended in all such cases (i.e. minimum volume of this medicine for sufficient anaesthetic effect).
Paediatric population:
This medicine is indicated in adults, adolescents and children aged more than 4 years. Special care has to be exercised when treating children below 4 years. The quantity to be injected should be determined by the age and weight of the child and the magnitude of the operation. The anaesthesia technique should be selected carefully. Painful anaesthesia techniques should be avoided. The behaviour of the child during treatment has to be monitored carefully. The average dose to be used is in the range of 20 mg to 30 mg lidocaine hydrochloride per session. The dose in mg of lidocaine hydrochloride which can be administered in children may alternatively be calculated from the expression: child's weight (in kilograms) x 1.33.
The quantity to be injected should be determined by the age and weight of the child and the magnitude of the operation.

Due to the fact that lidocaine diffuses rapidly into tissues and the density of bones is lower in children compared to adults, infiltration anaesthesia instead of conduction anaesthesia can be preferred in paediatric population.
Maxi rn u rn Reco rn men d ed D osa q e:
Adults:
For healthy adults, the maximum dose of the active ingredient lidocaine hydrochloride with vasoconstrictor admixture is 7 mg/kg body weight. Example: The maximum dose for a 70 kg patient is 500 mg. However, due to the addition of epinephrine 12.5 pg/ml, the maximum administered quantity of 16 ml solution for injection or 9 cartridges (equivalent to 0.2 mg epinephrine, maximum dose) must not be exceeded.
Children:
The quantity to be injected should be determined by the age and weight of the child and the magnitude of the operation. Do not exceed the equivalent of 5 mg lidocaine hydrochloride/kg bodyweight or 0.250 ml this medicine/kg bodyweight.

Method of administration
Dental use
To avoid intravascular injection, aspiration control at least in two planes (rotation of the needle by 180°) must always be carefully undertaken, although a negative aspiration result does not safely rule out an unintentional and unnoticed intravascular injection.
The injection rate should not exceed 0.5 ml in 15 seconds, i.e. 1 cartridge per minute.
Major systemic reactions as a result of accidental intravascular injection can be avoided in most cases by an injection technique - after aspiration slow injection of 0.1-0.2 mi and slow application of the rest - not earlier than 20-30 seconds later.
Opened cartridges must not be used in other patients. Residues must be discarded (see section 6.6).
4.3 Contraindications
This medicine must riot be used iri
- patients with (a history of) hypersensitivity to the active substances, sodium sulphite (E221) or to any of the other excipients,
- patients with haemorrhagic diatheses - increased bleeding risk particularly with nerve-block anaesthesia.
Due to the active substance lidocairie, this medicine must not be used iri the event of
- known allergy or hypersensitivity to local anaesthetics of the amide type,
- severe, uncontrolled or untreated excitation and conduction disorders of the heart (e.g. grade li and III AV block, pronounced bradycardia),
- acutely decompensated heart failure,
- severe hypotension,
- injection into an inflamed area because of treatment failure due to reduced penetration of lidocairie into the inflamed area.
Due to the content of epinephrine as a vasoconstrictor admixture, this medicine must riot be used iri the event of
- Heart diseases such as:
- unstable angina pectoris,
- recent myocardial infarction,
- recent coronary artery bypass surgery,
- refractory arrhythmias and paroxysmal tachycardia or high-frequency, continuous arrhythmia,
- untreated or uncontrolled severe hypertension,
- untreated or uncontrolled congestive heart failure,
- concomitant treatment with monoamine oxidase (MAO) inhibitors or tricyclic antidepressants (see section 4.5).
- This medicine is not allowed to be used in acra of extremities
Due to the content of sulphite as excipient, this medicine is not allowed to be used in the event of
- allergy or hypersensitivity to sulphite,
- severe bronchial asthma.
This medicine can provoke acute allergic reactions with anaphylactic symptoms (e.g. bronchospasm).
4.4 Special warnings and precautions for use Special warnings
This medicine must be used with particular caution iri the event of
- severe impairment to the renal function,
- angina pectoris (see section 4.2 and 4.3),
- arteriosclerosis,
- considerably impaired blood coagulation or ariticoagulatory treatment,
- uncontrolled or untreated hyperthyroidism,
- narrow-angle glaucoma,
- diabetes meiiitus,
- lung diseases - particularly allergic asthma bronchiale,
- pheochrornocytorna,
- methemoglobinemia.
Dental practitioner who employ local anaesthetic agents should be well versed iri diagnosis and management of emergencies which may arise from their uses.
Inadvertent intravascular application must be avoided (see section 4.2). Accidental intravascular injection or accidental overdose may be associated with convulsions, followed by central nervous system depression or cardiorespiratory arrest (see section 4.9). Resuscitative equipment, oxygen, and other resuscitative drugs should be available for immediate use.
The product should be administered with caution in patients with impaired cardiovascular function since they may be less able to compensate for functional changes associated with the prolongation of A-V conduction which might be caused by these drugs.
Since amide-type local anaesthetics are also metabolised by the liver, this medicine should be used with caution in patients with hepatic diseases. Patients with severe hepatic diseases are at greater risk of developing toxic plasma concentration.
The product should be administered with caution to patients with history of epilepsy, particularly high doses should be avoided.
The lower blood flow in the pulp tissue due to the content of epinephrine and thus the risk to overlook an opened pulp has to be taken into account regarding cavity or crown preparations.
There is a possibility of positive results on doping tests performed on sportsmen. Lidocaine is not listed on the current WADA list, and the listed epinephrine is not forbidden if used as vasoconstrictor iri local anaesthetics. Iri patients taking anticoagulants or platelet aggregation inhibitors (e.g. heparin or acetylsalicylic acid) the overall risk of bleeding is increased.
An inadvertent vasopuncture when administering the local anaesthetic can lead to serious bleeding.
This medicinal product contains less than 1 mmol (23 mg) sodium per 1.7 ml i.e. essentially "sodium free".
E221 sodium sulphite: May rarely cause severe hypersensitivity reactions and bronchospasm.
Information to the patients: The patient should be advised to exert caution to avoid inadvertent trauma to the lips, tongue, cheek mucosae or soft palate when these structures are anesthetized. The ingestion of food should therefore be postponed until normal function returns.
Precautions for use:
Each time a local anaesthetic is used the following medicinal products/ therapy as well asari indwelling i.v. catheter set should be available:
- Anti-convulsant medicines (benzodiazepines e.g. diazepam), myorelaxants, glucocorticoids, atropine and vasopressors or adrenaline as well as an electrolyte solution for a severe allergic or anaphylactic reaction.
- Resuscitating equipment (in particular a source of oxygen) enabling artificial ventilation if necessary.
- Careful and constant monitoring of cardiovascular and respiratory (adequacy of ventilation) vital signs and the patients state of consciousness should be monitored after each local anaesthetic injection. Restlessness, anxiety, tinnitus, dizziness, blurred vision, tremors, depression, or drowsiness may be early warning signs of central nervous system toxicity (see section 4.9).
4.5 Interaction with other medicinal products and other forms of interaction
Interactions affecting the use of this medicinal product:
• Contraindicated combinations:
Patients taking MAO inhibitors or tricyclic antidepressants The sympathomimetic effect of epinephrine can be intensified by the simultaneous intake of MAO inhibitors or tricyclic antidepressants (see also section 4.3).
• Concomitant use is not recommended:
Patients taking phenothiazines
Phenothiazines may reduce or reverse the pressor effect of epinephrine. Concurrent use of these agents should generally be avoided, in situations when concurrent therapy is necessary, careful patient monitoring is essential.
Patients taking non-selective beta-biockers The concomitant administration of non-cardioseiective (3-blockers can lead to an increase in blood pressure due to the epinephrine in this medicine.
Inhaiational anaesthestics
Certain inhaiational anaesthetics, such as halothane, can sensitise the heart to catecholamines and therefore induce arrhythmias following administration of this medicine.
Vasopressor and ergot-type oxytocic drugs Lidocairie hydrochloride with epinephrine 1:80,000 or other vasopressors should not be used concomitantly with ergot-type oxytocic drugs, because a severe persistent hypertension may occur.
• Precaution including dose adjustment:
Local anaesthetics
Caution is advised if lidocaine with epinephrine is used concurrently with other local anaesthetics. The toxic effects of local anaesthetics are additive. A major cause of adverse reactions appears to be excessive plasma concentrations, which may be due to accidental intravasai administration, slow metabolic degradation or overdosing.
Interactions resulting iri clinically relevant changes on the use of other medicinal products:
• Concomitant use is not recommended:
Patients taking oral anti diabetics
Epinephrine can inhibit insulin release in the pancreas and thus diminish the effect of oral antidiabetics.
Paediatric population
No significant differences can be expected regarding drug interactions between adult and paediatric population.
4.6 Fertility, pregnancy and lactation Pregnancy
For this medicine no clinical data on exposed pregnancies are available. Lidocaine animal studies do not indicate direct or indirect harmful effects with respect to reproductive toxicity at doses 6.6 times the human dose (see section 5.3). Animal studies carried out with epinephrine have shown reproductive toxicity (see section 5.3). The potential risk for humans is unknown.
Caution should be exercised when prescribing to pregnant women. This medicine should be used during pregnancy only if the potential benefit justifies the potential risk to the foetus.
Breast-feeding
Lidocairie is excreted iri breast milk with a rni!k:p!asma ratio of 0.4.
No information is available on the use of epinephrine during breast feeding. A decision on whether to continue/discontinue breast-feeding or to continue/discontinue therapy with this medicine should be made taking into account the benefit of breast-feeding to the child and the benefit of this medicine therapy to the women. Therefore, nursing mothers should milk and discard the first mother's milk following anaesthesia with lidocairie.
Fertility
Iri animal studies no effects on fertility were seen (see section 5.3).
4.7 Effects on the ability to drive and use machines
Although test patients have shown no impairment of their normal reactions when driving a vehicle, the dentist has to assess in each case the possible impairment of safety when operating a motor vehicle or machinery. The patient should not leave the dental office earlier than 30 minutes after the injection.
4.8 Undesirable effects
a) Summary of the safety profile:
In general, the therapeutic use of this medicine can be regarded as very safe. The causality assessment in case of adverse events is difficult, because either the underlying dental disease or the dental procedure or the local anaesthetic may be the reason of an adverse event, and an explicit differentiation is not possible. The description of the safety profile of this medicine is based on data identified in published clinical studies and on the postmarketing surveillance data of the MAH.
Iri clinical studies, the most frequently observed adverse events were hypoaesthesia oral (74%), followed by drug ineffective (8.5%) as well as pain, procedural pain, toothache (0.25-1.26%). Nerve disturbances were iri clinical studies with exception of hypoaesthesia oral not observed, which may be explained by the low patient number. Postmarketing surveillance data confirm the pattern described in published clinical studies iri general, but indicated a lower overall incidence of adverse events. However it has to be considered that spontaneous reporting systems did not allow incidence calculation.
The overall risk of nerve disturbances (e.g. hypoaesthesia, paraesthesia, taste disorders) is low according to the postmarketing experience, in the case of suspected hypersensitivity reactions, allergy testing is recommended including testing of the single components of the medicinal product.

c) Description of selected adverse events:
Two types of adverse events are of special clinical interest, but not the most frequently reported adverse events. The presentation is based mainly on postmarketing surveillance data.
Nerve disturbances
Nerve disturbances in dentistry may have different reasons, caused by underlying dental disease, by dental procedure, but also by direct adverse events of dental local anaesthetics. With an observation frequency of one event per 10 millions of sold carpules the risk of such disturbances is low.
In the data compilation given above the most frequently reported nerve disturbance in clinical studies was oral hypoaesthesia (mainly lip numbness). It should be taken into account that the high number of oral hypoaesthesia reported in clinical studies may reflect only an individually increased duration of action of this medicine. During postmarketing surveillance, cases of facial palsy, hypoaesthesia facial and different adverse eye events (e.g. diplopia, accommodation disturbances) were identified indicating possibly anaesthesia related nerve disturbances. All of these adverse events were reversible.
Hypersensitivity reactions
Hypersensitivity reactions were only rarely identified in the postmarketing surveillance (6.41 events per 10 millions sold carpules). Mostly the reactions were non-serious (4.56/10 millions sold carpules), but life-threatening reactions cannot be fully excluded.The reactions included anaphylactic reactiorrs/shock, skin reactions and respiratory symptoms.
In the case of suspected hypersensitivity reaction, allergy testing is recommended including testing of the single components of the medicinal product.
d) Paediatric population
The observation during postmarketing surveillance does not reveal differences in the safety profile in children compared with those in adults.

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, Website: www.mhra.qov.uk/vellowcard
4.9 Overdose
Acute emergencies from local anaesthetics are generally related to high plasma levels encountered during therapeutic use or unintended and fast iritravasal administration of local anaesthetics. Symptoms of overdose may appear either immediately, caused by accidental intravascular injection or abnormal absorption conditions, e.g. in inflamed or intensive vascularised tissue, or later, caused by true overdose following an injection of excessive quantity of anaesthetic solution, and manifest themselves as central nervous and/or vascular symptoms.
Symptoms probably caused by lidocairie:
Cardiovascular symptoms (S0C Cardiac disorders, Vascular disorders, Investigations): blood pressure decreased, bradycardia, cardiac arrest, conduction disorder.
Central nervous symptoms (S0C Psychiatric disorders, Nervous system disorders, Ear and labyrinth disorders, Gastrointestinal disorders, Musculoskeletal and connective tissue disorders, Investigations): anxiety, coma, confusional state, dizziness, dysgeusia, grand mal convulsion, muscle twitching, nausea, respiratory paralysis, respiratory rate increased, restlessness, somnolence, tinnitus, tremor, vomiting.
The most dangerous symptoms regarding the outcome of such an event are: blood pressure decreased, cardiac arrest, conduction disorder, grand mal convulsion, respiratory paralysis, and somnolence/coma.
Syrnptorns probabIv caused by epi nephrine fadrenaline):
Pressure symptoms (SOC Vascular disorders, Investigations): blood pressure systolic increased, blood pressure diastolic increased, venous pressure increased, pulmonary arterial pressure increased, hypotension.
Cardiac symptoms (SOC Cardiac disorders): bradycardia, tachycardia, arrhythmia (e.g. atrial tachycardia, atrioventricular block, ventricular tachycardia, premature ventricular contractions).
These symptoms can result in life threatening situations as well as pulmonary oedema, cardiac arrest, kidney failure, and metabolic acidosis.
Therapy
If symptoms of overdose arise the application of the local anaesthetic has to be stopped.
General basic measures:
Diagnostics (respiration, circulation, consciousness), resuscitation and/or maintenance of the vital functions (respiration and circulation), administration of oxygen, intravenous access.
Elevation of the upper body, if necessary sublingual nifedipine.
Protect patients from concomitant injuries, if necessary benzodiazepines (e.g. diazepam iv).
Horizontal position, if necessary intravascular infusion of a whole electrolyte solution, vasopressors (e.g. etilefrine iv).
Atropine iv.
Anaphylactic shock: Contact emergency physician, in the meantime shock positioning, generous infusion of a whole electrolyte solution, if necessary epinephrine iv, cortisone iv.
Cardiovascular arrest: Immediate cardiopulmonary resuscitation, contact emergency physician.
5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Anaesthetics, local, ATC code N01B B52 Mechanism of action:
This medicine contains lidocairie which is a local anaesthetic of the amide type for dentistry arid leads to a reversible inhibition of the irritability of vegetative, sensory and motor nerve fibres. The blocking of voltage dependent Na+ channels on the membrane of the nerve fibre is supposed to be the mechanism of action of lidocaine.
Epinephrine leads locally to vasoconstriction and reduced blood supply, whereby the absorption of lidocairie is delayed. The result is a higher concentration of the local anaesthetic at the site of action over a longer period, as well as the reduction of systemic adverse side effects.
Pharmacodynamic effects:
Onset of local anaesthetic effects of this medicine occurs after a short latency period of 1-3 min with infiltration and after somewhat longer latency period after injection with nerve block anaesthesia (2 to 4 minutes after injection). The duration of complete anaesthesia with this medicine iri pulpal anaesthesia is 30 to 60 minutes, and iri soft-tissue anaesthesia 120 to 180 minutes.
Clinical efficacy and safety:
Success rates of anaesthesia with this medicine differ, depending on the kind of anaesthesia arid the factors already mentioned before. Iri general, success rates of about 90% or higher may be expected after single use if the drug is administered as indicated. The inferior alveolar nerve block has the greatest failure rate. Repeated or supplementary injections may be necessary iri the event of failure or in the event of prolonged dental procedures and surgery. Special conditions, e.g. acute irreversible pulpitis of mandibular molars, may require special or alternative anaesthetic techniques. Articaine 4% with epinephrine may provide better clinical efficacy iri such cases as reported by different authors, this medicine is usually tolerated well however, adverse reactions cannot be fully excluded (see section 4.8), in the event of overdose in particular (see section 4.9).
Paediatric population:
The use of this medicine iri paediatric population is considered for routine treatment. Dosages in paediatric population should be reduced considering age, body weight, physical condition arid the magnitude of the treatment (see section 4.2), together with complex measures to prevent painful experience arid to reduce anxiety, including sedation.
Since paediatric patients suffer relatively often traumatic injury to their still (residual) anaesthetized soft tissue following local anaesthesia administration in the dental office (reportedly 13%), local anaesthesia providing the appropriate duration of efficacy should be used.
5.2 Pharmacokinetic properties
Absorption:
Lidocaine is rapidly and extensively absorbed. The maximum plasma level of lidocaine from intraoral injection is achieved approximately after 10-20 minutes.
Distribution:
Lidocairie is bound up to 60 to 80% in the serum to plasma proteins. Lidocairie is widely distributed within the organism. The elimination half-life is 1.5 to 2 hours.
Biotrarisformatiori arid elimination:
Lidocairie is largely metabolised iri the liver and any alteration iri liver function or hepatic blood flowcari have a significant effect ori its pharmacokinetics and dosage requirements. Metabolism iri the liver is rapid and about 90% of the given dose is dealkylated to form mono-ethyiglycinexylidide and glycinexylidide. Less than 10% is excreted unchanged. The primary metabolite in urine is a conjugate of 4-hydroxy-2,6-dimethylaniline.
Lidocaine crosses the blood-brain and placental barriers.
Epinephrine is rapidly catabolized iri the liver and other tissues. The metabolites are excreted renally.
Special populations:
Effect of age: Lidocaine has been extensively investigated in elderly patients. A significantly longer half-life was found for lidocairie iri elderly patients. Reduced clearance was detected only iri elderly men, while the values iri females did riot differ significantly from younger individuals.
Dose reduction was sometimes suggested for elderly patients (reduction by approximately 1/3 to 1/2).
It is suggested that absorption may be faster and the Cmax higher in children than in adults, while dependent upon the administered drug, and due to the larger volume of distribution the Cm3X may also be lower and the terminal half-life longer iri children than iri adults. Lor children it seems preferable to use drugs with higher protein binding and a high hepatic extraction ratio such as articaine.
Renal and hepatic insufficiency:
The elimination half-life of lidocairie following ari intravenous bolus injection is typically 1.5 to 2.0 hours. Because of the rapid rate at which lidocairie is metabolized, any condition that affects liver function may alter lidocairie kinetics. The half-life may be doubled or more in patients with liver dysfunction. Renal dysfunction does not affect lidocairie kinetics but may increase the accumulation of metabolites.
5.3 Preclinical safety data
There is evidence that 2,6-xylidine, a metabolic product arising from lidocaine in the rat, and possibly also in man, can have mutagenic effects. This evidence is obtained from iri-vitro tests in which the said metabolite was used at very high, almost toxic concentrations. There is rio reason to believe at this time that the parent substance, lidocairie, is itself also mutagenic.
A carcinogenicity study of transplacental exposure and postnatal treatment of animals for two years with 2,6-xylidine iri rats demonstrated malignant and benign tumors predominantly iri the nasal cavities (ethmoturbinalia) by means of a highly sensitive test system (transplacental exposure arid postnatal treatment of animals for two years with very high doses). It does riot seem totally unlikely that these findings will be relevant to humans.
Lor this reason high doses of this medicine (lidocaine) should not be administered over longer periods.
While supratherapeutic doses of lidocairie and epinephrine administered under iri vitro or iri vivo experimental conditions to laboratory animals may affect fertilization and foetal development, harmful or other effects on female or male fertility are not expected based on animal studies at therapeutic doses of lidocairie and epinephrine (see section 4.6).
Environmental Risk Assessment (ERA):
