4. Clinical Particulars



4.1 Therapeutic Indications



Treatment of adults, adolescents and children, 6 years or older with diabetes mellitus, where treatment with insulin is required.



4.2 Posology And Method Of Administration



The potency of this preparation is stated in units. These units are exclusive to Apidra and are not the same as IU or the units used to express the potency of other insulin analogues (see section 5.1).



Apidra should be used in regimens that include an intermediate or long acting insulin or basal insulin analogue and can be used with oral hypoglycaemic agents.



The dose of Apidra should be individually adjusted.



Special populations



Renal impairment



The pharmacokinetic properties of insulin glulisine are generally maintained in patients with renal impairment. However, insulin requirements may be reduced in the presence of renal impairment (see section 5.2).



Hepatic impairment



The pharmacokinetic properties of insulin glulisine have not been investigated in patients with decreased liver function. In patients with hepatic impairment, insulin requirements may be diminished due to reduced capacity for gluconeogenesis and reduced insulin metabolism.



Elderly



Limited pharmacokinetic data are available in elderly patients with diabetes mellitus. Deterioration of renal function may lead to a decrease in insulin requirements.



Paediatric population



There is insufficient clinical information on the use of Apidra in children younger than the age of 6 years.



Administration



Vials: Intravenous use



Apidra can be administered intravenously. This should be carried out by health care professionals.



Apidra must not be mixed with glucose or Ringer's solution or with any other insulin.



Vials, cartridges and OptiSet: Subcutaneous use



Apidra should be given by subcutaneous injection shortly (0-15 min) before or soon after meals or by continuous subcutaneous pump infusion.



Apidra should be administered subcutaneously in the abdominal wall, thigh or deltoid or by continuous infusion in the abdominal wall. Injection sites and infusion sites within an injection area (abdomen, thigh or deltoid) should be rotated from one injection to the next. The rate of absorption, and consequently the onset and duration of action, may be affected by the injection site, exercise and other variables. Subcutaneous injection in the abdominal wall ensures a slightly faster absorption than other injection sites (see section 5.2).



Care should be taken to ensure that a blood vessel has not been entered. After injection, the site of injection should not be massaged. Patients must be educated to use proper injection techniques.



When used with a subcutaneous insulin infusion pump, Apidra must not be mixed with diluents or any other insulin.



Mixing with insulins



When administered as a subcutaneous injection, Apidra must not be mixed with other medicinal products except NPH human insulin.



Before using OptiSet, the Instructions for use included in the Package leaflet must be read carefully (see section 6.6). For further details on handling all preparations, see section 6.6.



4.3 Contraindications



Hypersensitivity to the active substance or to any of the excipients.



Hypoglycaemia.



4.4 Special Warnings And Precautions For Use



Transferring a patient to another type or brand of insulin should be done under strict medical supervision. Changes in strength, brand (manufacturer), type (regular, neutral protamine Hagedorn [NPH], lente, long-acting, etc.), origin (animal, human, human insulin analogue) and/or method of manufacture may result in the need for a change in dose. Concomitant oral antidiabetic treatment may need to be adjusted.



The use of inadequate doses or discontinuation of treatment, especially in insulin-dependent diabetic, may lead to hyperglycaemia and diabetic ketoacidosis; conditions which are potentially lethal.



The time of occurrence of hypoglycaemia depends on the action profile of the insulins used and may, therefore, change when the treatment regimen is changed.



Conditions which may make the early warning symptoms of hypoglycaemia different or less pronounced include long duration of diabetes, intensified insulin therapy, diabetic nerve disease, medicinal products such as beta blockers or after transfer from animal-source insulin to human insulin.



Adjustment of dose may be also necessary if patients undertake increased physical activity or change their usual meal plan. Exercise taken immediately after a meal may increase the risk of hypoglycaemia.



When compared with soluble human insulin, if hypoglycaemia occurs after an injection with rapid acting analogues, it may occur earlier.



Uncorrected hypoglycaemic or hyperglycaemic reactions can cause loss of consciousness, coma, or death.



Insulin requirements may be altered during illness or emotional disturbances. .



Medication errors have been reported in which other insulins, particularly long-acting insulins, have been accidentally administered instead of insulin glulisine. Insulin label must always be checked before each injection to avoid medication errors between insulin glulisine and other insulins.



This medicinal product contains less than 1 mmol (23 mg) sodium per dose, i.e. it is essentially 'sodium-free'.



Apidra contains metacresol, which may cause allergic reactions.



Combination of Apidra with pioglitazone



Cases of cardiac failure have been reported when pioglitazone was used in combination with insulin, especially in patients with risk factors for development of cardiac heart failure. This should be kept in mind if treatment with the combination of pioglitazone and Apidra is considered. If the combination is used, patients should be observed for signs and symptoms of heart failure, weight gain and oedema. Pioglitazone should be discontinued if any deterioration in cardiac symptoms occurs.



Pens to be used with Apidra cartridges



The Apidra cartridges should only be used with the following pens: OptiPen, ClikSTAR and Autopen 24 and should not be used with any other reusable pen as the dosing accuracy has only been established with the listed pens.



Handling of the OptiSet pen



Before using OptiSet, the Instructions for use included in the Package leaflet must be read carefully.



OptiSet has to be used as recommended in these Instructions for use (see section 6.6).



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



Studies on pharmacokinetic interactions have not been performed. Based on empirical knowledge from similar medicinal products, clinically relevant pharmacokinetic interactions are unlikely to occur.



A number of substances affect glucose metabolism and may require dose adjustment of insulin glulisine and particularly close monitoring.



Substances that may enhance the blood-glucose-lowering activity and increase susceptibility to hypoglycaemia include oral antidiabetic agents, angiotensin converting enzyme (ACE) inhibitors, disopyramide, fibrates, fluoxetine, monoamine oxidase inhibitors (MAOIs), pentoxifylline, propoxyphene, salicylates and sulfonamide antibiotics.



Substances that may reduce the blood-glucose-lowering activity include corticosteroids, danazol, diazoxide, diuretics, glucagon, isoniazid, phenothiazine derivatives, somatropin, sympathomimetic agents (e.g. epinephrine [adrenaline], salbutamol, terbutaline), thyroid hormones, estrogens, progestins (e.g. in oral contraceptives), protease inhibitors and atypical antipsychotic medicinal products (e.g. olanzapine and clozapine).



Beta-blockers, clonidine, lithium salts or alcohol may either potentiate or weaken the blood-glucose-lowering activity of insulin. Pentamidine may cause hypoglycaemia, which may sometimes be followed by hyperglycaemia.



In addition, under the influence of sympatholytic medicinal products such as beta-blockers, clonidine, guanethidine and reserpine, the signs of adrenergic counter-regulation may be reduced or absent.



4.6 Pregnancy And Lactation



Pregnancy



There are no adequate data on the use of insulin glulisine in pregnant women.



Animal reproduction studies have not revealed any differences between insulin glulisine and human insulin regarding pregnancy, embryonal/foetal development, parturition or postnatal development (see section 5.3).



Caution should be exercised when prescribing to pregnant women. Careful monitoring of glucose control is essential.



It is essential for patients with pre-existing or gestational diabetes to maintain good metabolic control throughout pregnancy. Insulin requirements may decrease during the first trimester and generally increase during the second and third trimesters. Immediately after delivery, insulin requirements decline rapidly.



Lactation



It is unknown whether insulin glulisine is excreted in human milk, but in general insulin does not pass into breast milk and is not absorbed after oral administration.



Breast-feeding mothers may require adjustments in insulin dose and diet.



4.7 Effects On Ability To Drive And Use Machines



The patient's ability to concentrate and react may be impaired as a result of hypoglycaemia or hyperglycaemia or, for example, as a result of visual impairment. This may constitute a risk in situations where these abilities are of special importance (e.g. driving a car or operating machinery).



Patients should be advised to take precautions to avoid hypoglycaemia whilst driving. This is particularly important in those who have reduced or absent awareness of the warning symptoms of hypoglycaemia or have frequent episodes of hypoglycaemia. The advisability of driving should be considered in these circumstances.



4.8 Undesirable Effects



Hypoglycaemia, the most frequent undesirable effect of insulin therapy, may occur if the insulin dose is too high in relation to the insulin requirement.



The following related adverse reactions from clinical studies were listed below by system organ class and in order of decreasing incidence (very common:



Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness.

Systemic hypersensitivity reactions



 


Metabolism and nutrition disorders



Symptoms of hypoglycaemia usually occur suddenly. They may include cold sweats, cool pale skin, fatigue, nervousness or tremor, anxiousness, unusual tiredness or weakness, confusion, difficulty in concentration, drowsiness, excessive hunger, vision changes, headache, nausea and palpitation.



Hypoglycaemia can become severe and may lead to unconsciousness and/or convulsions and may result in temporary or permanent impairment of brain function or even death.



Skin and subcutaneous tissue disorders



Local hypersensitivity reactions (redness, swelling and itching at the injection site) may occur during treatment with insulin. These reactions are usually transitory and normally they disappear during continued treatment.



Lipodystrophy may occur at the injection site as a consequence of failure to rotate injection sites within an area.



General disorders and administration site conditions



Systemic hypersensitivity reactions may include urticaria, chest tightness, dyspnea, allergic dermatitis and pruritus. Severe cases of generalized allergy, including anaphylactic reaction, may be life-threatening.



4.9 Overdose



Hypoglycaemia may occur as a result of an excess of insulin activity relative to food intake and energy expenditure.



There are no specific data available concerning overdoses with insulin glulisine. However, hypoglycaemia may develop over sequential stages:



Mild hypoglycaemic episodes can be treated by oral administration of glucose or sugary products. It is therefore recommended that the diabetic patient constantly carries some sugar lumps, sweets, biscuits or sugary fruit juice.



Severe hypoglycaemic episodes, where the patient has become unconscious, can be treated by glucagon (0.5 mg to 1 mg) given intramuscularly or subcutaneously by a person who has received appropriate instruction, or by glucose given intravenously by a healthcare professional. Glucose must also be given intravenously, if the patient does not respond to glucagon within 10 to 15 minutes.



Upon regaining consciousness, administration of oral carbohydrate is recommended for the patient in order to prevent relapse.



After an injection of glucagon, the patient should be monitored in a hospital in order to find the reason for this severe hypoglycaemia and prevent other similar episodes.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Pharmacotherapeutic group: Insulins and analogues for injection, fast-acting. ATC code: A10AB06



Insulin glulisine is a recombinant human insulin analogue that is equipotent to regular human insulin.



Insulin glulisine has a more rapid onset of action and a shorter duration of action than regular human insulin.



The primary activity of insulins and insulin analogues, including insulin glulisine, is regulation of glucose metabolism. Insulins lower blood glucose levels by stimulating peripheral glucose uptake, especially by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulin inhibits lipolysis in the adipocyte, inhibits proteolysis and enhances protein synthesis.



Studies in healthy volunteers and patients with diabetes demonstrated that insulin glulisine is more rapid in onset of action and of shorter duration of action than regular human insulin when given subcutaneously. When insulin glulisine is injected subcutaneously, the glucose lowering activity will begin within 10 – 20 minutes. After intravenous administration, a faster onset and shorter duration of action, as well as a greater peak response were observed as compared with subcutaneous administration. The glucose-lowering activities of insulin glulisine and regular human insulin are equipotent when administered by intravenous route. One unit of insulin glulisine has the same glucose - lowering activity as one unit of regular human insulin.



Dose proportionality



In a study with 18 male subjects with diabetes mellitus type 1 aged 21 to 50 years, insulin glulisine displayed dose-proportional glucose lowering effect in the therapeutic relevant dose range 0.075 to 0.15 Units/kg, and less than proportional increase in glucose lowering effect with 0.3 Units/kg or higher, like human insulin.



Insulin glulisine takes effect about twice as fast as regular human insulin and completes the glucose lowering effect about 2 hours earlier than regular human insulin.



A phase I study in patients with type 1 diabetes mellitus assessed the glucose lowering profiles of insulin glulisine and regular human insulin administered subcutaneously at a dose of 0.15 Units/kg, at different times in relation to a 15-minute standard meal. Data indicated that insulin glulisine administered 2 minutes before the meal gives similar postprandial glycemic control compared to regular human insulin given 30 minutes before the meal. When given 2 minutes prior to meal, insulin glulisine provided better postprandial control than regular human insulin given 2 minutes before the meal. Insulin glulisine administered 15 minutes after starting the meal gives similar glycemic control as regular human insulin given 2 minutes before the meal (see figure 1).









Figure 1: Average glucose



Insulin glulisine given 15 minutes (GLULISINE post) after start of a meal compared to regular human insulin given 2 minutes (REGULAR pre) before start of the meal (figure 1C). On the x-axis, zero (arrow) is the start of a 15-minute meal.



Obesity



A phase I study carried out with insulin glulisine, lispro and regular human insulin in an obese population has demonstrated that insulin glulisine maintains its rapid-acting properties. In this study, the time to 20 % of total AUC and the AUC (0-2h) representing the early glucose lowering activity were respectively of 114 minutes and 427 mg/kg for insulin glulisine, 121 minutes and 354 mg/kg for lispro, 150 minutes and 197 mg/kg for regular human insulin (see figure 2).





Figure 2: Glucose infusion rates (GIR) after subcutaneous injection of 0.3 Units/kg of insulin glulisine (GLULISINE) or insulin lispro (LISPRO) or regular human insulin (REGULAR) in an obese population.



Another phase I study with insulin glulisine and insulin lispro in a non-diabetic population in 80 subjects with a wide range of body mass indices (18-46 kg/m²) has demonstrated that rapid action is generally maintained across a wide range of body mass indices (BMI), while total glucose lowering effect decreases with increasing obesity.



The average total GIR AUC between 0–1 hour was 102±75 mg/kg and 158±100 mg/kg with 0.2 and 0.4 Units/kg insulin glulisine, respectively, and was 83.1±72.8 mg/kg and 112.3±70.8 mg/kg with 0.2 and 0.4 Units/kg insulin lispro respectively.



A phase I study in 18 obese patients with type 2 diabetes mellitus (BMI between 35 and 40 kg/m2) with insulin glulisine and insulin lispro [90% CI:0.81, 0.95 (p=<0.01)]has shown that insulin glulisine effectively controls diurnal post-prandial blood glucose excursions.



Clinical studies



Type 1 diabetes mellitus-Adults



In a 26-week phase III clinical study comparing insulin glulisine with insulin lispro both injected subcutaneously shortly (0-15 minutes) before a meal in patients with type 1 diabetes mellitus using insulin glargine as basal insulin, insulin glulisine was comparable to insulin lispro for glycemic control as reflected by changes in glycated haemoglobin (expressed as HbA1c equivalent) from baseline to endpoint. Comparable self-monitored blood glucose values were observed. No increase in the basal insulin dose was needed with insulin glulisine, in contrast to insulin lispro.



A 12-week phase III clinical study performed in patients with type 1 diabetes mellitus receiving insulin glargine as basal therapy indicate that the immediate postmeal administration of insulin glulisine provides efficacy that was comparable to immediate premeal insulin glulisine (0-15 minutes) or regular insulin (30-45 minutes).



In the per protocol population there was a significantly larger observed reduction in GHb in the premeal glulisine group compared with the regular insulin group.



Type 1 diabetes mellitus-Paediatric



A 26-week phase III clinical study compared insulin glulisine with insulin lispro both injected subcutaneously shortly (0-15 minutes) before a meal in children (4-5 years: n=9; 6-7 years: n=32 and 8-11 years: n=149) and adolescents (12-17 years: n=382) with type 1 diabetes mellitus using insulin glargine or NPH as basal insulin. Insulin glulisine was comparable to insulin lispro for glycaemic control as reflected by changes in glycated haemoglobin (GHb expressed as HbA1c equivalent) from baseline to endpoint and by self-monitored blood glucose values.



There is insufficient clinical information on the use of Apidra in children younger than the age of 6 years.



Type 2 diabetes mellitus-Adults



A 26-week phase III clinical study followed by a 26-week extension safety study was conducted to compare insulin glulisine (0-15 minutes before a meal) with regular human insulin (30-45 minutes before a meal) injected subcutaneously in patients with type 2 diabetes mellitus also using NPH insulin as basal insulin. The average body mass index (BMI) of patients was 34.55 kg/ m2. Insulin glulisine was shown to be comparable to regular human insulin with regard to glycated haemoglobin (expressed as HbA1c equivalent) changes from baseline to the 6-month endpoint (-0.46% for insulin glulisine and -0.30% for regular human insulin, p=0.0029) and from baseline to the 12-month endpoint (-0.23% for insulin glulisine and -0.13% for regular human insulin, difference not significant). In this study, the majority of patients (79%) mixed their short acting insulin with NPH insulin immediately prior to injection and 58% of subjects used oral hypoglycemic agents at randomization and were instructed to continue to use them at the same dose.



Race and gender



In controlled clinical trials in adults, insulin glulisine did not show differences in safety and efficacy in subgroup analyses based on race and gender.



5.2 Pharmacokinetic Properties



In insulin glulisine the replacement of the human insulin amino acid asparagine in position B3 by lysine and the lysine in position B29 by glutamic acid favors more rapid absorption.



In a study with 18 male subjects with diabetes mellitus type 1, aged 21 to 50 years, insulin glulisine displays dose-proportionality for early, maximum and total exposure in the dose range 0.075 to 0.4 Units/kg.



Absorption and bioavailability



Pharmacokinetic profiles in healthy volunteers and diabetes patients (type 1 or 2) demonstrated that absorption of insulin glulisine was about twice as fast with a peak concentration approximately twice as high as compared to regular human insulin.



In a study in patients with type 1 diabetes mellitus after subcutaneous administration of 0.15 Units/kg, for insulin glulisine the Tmax was 55 minutes and Cmax was 82 ± 1.3 μUnits/ml compared to a Tmax of 82 minutes and a Cmax of 46 ± 1.3 μUnits/ml for regular human insulin. The mean residence time of insulin glulisine was shorter (98 min) than for regular human insulin (161 min) (see figure 3).





Figure 3: Pharmacokinetic profile of insulin glulisine and regular human insulin in type 1 diabetes mellitus patients after a dose of 0.15 Units/kg.



In a study in patients with type 2 diabetes mellitus after subcutaneous administration of 0.2 Units/kg insulin glulisine, the Cmax was 91 μUnits/ml with the interquartile range from 78 to 104 μUnits/ml.



When insulin glulisine was injected subcutaneously into abdomen, deltoid and thigh, the concentration-time profiles were similar with a slightly faster absorption when administered in the abdomen compared to the thigh. Absorption from deltoid sites was in-between (see section 4.2). The absolute bioavailability (70%) of insulin glulisine was similar between injection sites and of low intra-subject variability (11%CV). Intravenous bolus administration of insulin glulisine resulted in a higher systemic exposure when compared to subcutaneous injection, with a Cmax approximately 40-fold higher.



Obesity



Another phase I study with insulin glulisine and insulin lispro in a non-diabetic population in 80 subjects with a wide range of body mass indices (18-46 kg/m²) has demonstrated that rapid absorption and total exposure is generally maintained across a wide range of body mass indices.



The time to 10% of total INS exposure was reached earlier by approximately 5–6 min with insulin glulisine.



Distribution and elimination



The distribution and elimination of insulin glulisine and regular human insulin after intravenous administration is similar with volumes of distribution of 13 l and 22 l and half-lives of 13 and 18 minutes, respectively.



After subcutaneous administration, insulin glulisine is eliminated more rapidly than regular human insulin with an apparent half-life of 42 minutes compared to 86 minutes. In an across study analysis of insulin glulisine in either healthy subjects or subjects with type 1 or type 2 diabetes mellitus the apparent half-life ranged from 37 to 75 minutes (interquartile range).



Insulin glulisine shows low plasma protein binding, similar to human insulin.



Special populations



Renal impairment



In a clinical study performed in non-diabetic subjects covering a wide range of renal function (CrCl> 80 ml/min, 30-50 ml/min, < 30 ml/min), the rapid-acting properties of insulin glulisine were generally maintained. However, insulin requirements may be reduced in the presence of renal impairment.



Hepatic impairment



The pharmacokinetic properties have not been investigated in patients with impaired liver function.



Elderly



Very limited pharmacokinetic data are available for elderly patients with diabetes mellitus.



Children and adolescents



The pharmacokinetic and pharmacodynamic properties of insulin glulisine were investigated in children (7-11 years) and adolescents (12-16 years) with type 1 diabetes mellitus. Insulin glulisine was rapidly absorbed in both age groups, with similar Tmax and Cmax as in adults (see section 4.2).



Administered immediately before a test meal, insulin glulisine provided better postprandial control than regular human insulin, as in adults (see section 5.1). The glucose excursion (AUC 0-6h) was 641 mg.h.dl-1 for insulin glulisine and 801 mg.h.dl-1 for regular human insulin.



5.3 Preclinical Safety Data



Non-clinical data did not reveal toxicity findings others than those linked to the blood glucose lowering pharmacodynamic activity (hypoglycemia), different from regular human insulin or of clinical relevance for humans.

6.6 Special Precautions For Disposal And Other Handling



Insulin label must always be checked before each injection to avoid medication errors between insulin glulisine and other insulins (see section 4.4)



Mixing with insulins



When mixed with NPH human insulin, Apidra should be drawn into the syringe first. Injection should be given immediately after mixing as no data are available regarding the mixtures made up a significant time before injection.



Vials: Intravenous use



Apidra should be used at a concentration of 1 Unit/ml insulin glulisine in infusion systems with sodium chloride 9 mg/ml (0.9%) solution for infusion with or without 40 mmol/l potassium chloride using coextruded polyolefin/polyamide plastic infusion bags with a dedicated infusion line. Insulin glulisine for intravenous use at a concentration of 1 Unit/ml is stable at room temperature for 48 hours.



After dilution for intravenous use, the solution should be inspected visually for particulate matter prior to administration. It must only be used if the solution is clear and colourless, not when cloudy or with visible particles.



Apidra was found to be incompatible with Glucose 5% solution and Ringer's solution and, therefore, must not be used with these solution fluids. The use of other solutions has not been studied.



Vials: Subcutaneous use



Apidra vials are for use with insulin syringes with the corresponding unit scale and for use with an insulin pump system (see section 4.2).



Inspect the vial before use. It must only be used if the solution is clear, colourless, with no solid particles visible. Since Apidra is a solution, it does not require resuspension before use.



Continuous subcutaneous infusion pump



Apidra may be used for Continuous Subcutaneous Insulin Infusion (CSII) in pump systems suitable for insulin infusion with the appropriate catheters and reservoirs.



Patients using CSII should be comprehensively instructed on the use of the pump system. The infusion set and reservoir should be changed every 48 hours using aseptic technique.



Patients administering Apidra by CSII must have alternative insulin available in case of pump system failure.



Cartridges



The Apidra cartridges are to be used only in conjunction with OptiPen, ClikSTAR or Autopen 24 (see section 4.4).



The pen should be used as recommended in the information provided by the device manufacturer.



The manufacturer's instructions for using the pen must be followed carefully for loading the cartridge, attaching the needle, and administering the insulin injection. Inspect the cartridge before use. It must only be used if the solution is clear, colourless, with no solid particles visible. Before insertion of the cartridge into the reusable pen, the cartridge must be stored at room temperature for 1 to 2 hours. Air bubbles must be removed from the cartridge before injection (see instruction for using pen). Empty cartridges must not be refilled.



If the pen malfunctions (see instructions for using the pen), the solution may be drawn from the cartridge into a syringe (suitable for an insulin with 100 Units/ml) and injected. If the insulin pen is damaged or not working properly (due to mechanical defects) it has to be discarded, and a new insulin pen has to be used.



To prevent any kind of contamination, the re-usable pen should be used by a single patient only.



Optiset pre-filled pen



Before first use, the pen must be stored at room temperature for 1 to 2 hours.



Inspect the cartridge before use. It must only be used if the solution is clear, colourless, with no solid particles visible, and if it is of water-like consistency. Since Apidra is a solution, it does not require resuspension before use.



Empty pens must never be used and must be properly discarded.



To prevent any kind of contamination, the use of the pre-filled pen should remain strictly for a single patient use.



Handling of the pen



The patient should be advised to read the instructions for use included in the package leaflet carefully before using OptiSet.





Schematic diagram of the pen



Important information for use of OptiSet:



• A new needle must always be attached before each use. Only needles that are compatible for use with OptiSet must be used.



• A safety test must always be performed before each injection.



• If a new OptiSet is used the initial safety test must be done with the 8 units preset by the manufacturer.



• The dosage selector can only be turned in one direction.



• The dosage selector (change the dose) must never be turned after injection button has been pulled out.



• This pen is only for the patients use. It must not be shared with anyone else.



• If the injection is given by another person, special caution must be taken by this person to avoid accidental needle injury and transmission of infection.



• OptiSet must never be used if it is damaged or if the patient is not sure if it is working properly.



• The patient must always have a spare OptiSet available in case the OptiSet is lost or damaged.



Storage Instructions



Please check section 6.4 of this SPC for instructions on how to store OptiSet.



If OptiSet is in cool storage, it should be taken out 1 to 2 hours before injection to allow it to warm up. Cold insulin is more painful to inject.



The used OptiSet must be discarded as required by your local authorities.



Maintenance



OptiSet has to be protected from dust and dirt.



The outside of the OptiSet can be cleaned by wiping it with a damp cloth.



The pen must not be soaked, washed or lubricated as this may damage it.



OptiSet is designed to work accurately and safely. It should be handled with care. The patient should avoid situations where OptiSet may be damaged. If the patient is concerned that the OptiSet may be damaged, he must use a new one.



Step 1 Check the Insulin



After removing the pen cap, the label on the pen and the insulin reservoir should be checked to make sure it contains the correct insulin.



The appearance of insulin should also be checked: the insulin solution must be clear, colourless, with no solid particles visible, and must have a water-like consistency. Do not use this OptiSet if the insulin is cloudy, coloured or has particles.



Step 2 Attach the needle



The needle should be carefully attached straight onto the pen.



Step 3 Perform a safety test



Prior to each injection a safety test has to be performed.



For a new and unused OptiSet, a dose of 8 units is already preset by the manufacturer for the first safety test.



In-use OptiSet, a dose of 2 units has to be selected by turning the dosage selector forward till the dose arrow points to 2. The dosage selector will only turn in one direction.



The injection button should be pulled out completely in order to load the dose. The dosage selector must never be turned after the injection button has been pulled out.



The outer and inner needle caps should be removed. The outer cap should be kept to remove the used needle.



While holding the pen with the needle pointing upwards, the insulin reservoir should be tapped with the finger so that any air bubbles rise up towards the needle.



Then the injection button should be pressed all the way in.



If insulin has been expelled through the needle tip, then the pen and the needle are working properly. If no insulin appears at the needle tip, step 3 should be repeated two more times until insulin appears at the needle tip. If still no insulin comes out, change the needle, as it might be blocked and try again. If no insulin comes out after changing the needle, the OptiSet may be damaged. This OptiSet must not be used.



Step 4 Select the dose



The dose can be set in steps of 2 units, from a minimum of 2 units to a maximum of 40 units. If a dose greater than 40 units is required, it should be given as two or more injections.



The patient must always check if he has enough insulin for the dose.



The residual insulin scale on the transparent insulin reservoir shows approximately how much insulin remains in the OptiSet. This scale must not be used to set the insulin dose.



If the black plunger is at the beginning of the coloured bar, then there are approximately 40 units of insulin available.



If the black plunger is at the end of the coloured bar, then there are approximately 20 units of insulin available.



The dosage selector should be turned forward until the dose arrow points to the required dose.



Step 5 Load the dose



The injection button should be pulled out as far as it will go in order to load the pen.



The patient must always check if the selected dose is fully loaded. The injection button only goes out as far as the amount of insulin that is left in the reservoir.



The injection button allows checking the actual loaded dose. The injection button must be held out under tension during this check. The last thick line visible on the injection button shows the amount of insulin loaded. When the injection button is held out only the top part of this thick line can be seen.



Step 6 Inject the dose



The patient should be informed on the injection technique by his health care professional. The needle should be inserted into the skin



The injection button should be pressed all the way in. A clicking sound can be heard, which will stop when the injection button has been pressed in completely. Then the injection button should be held down 10 seconds before withdrawing the needle from the skin. This ensures that the full dose of insulin has been delivered.



Step 7 Remove and discard the needle



The needle should be removed after each injection and discarded. This helps prevent contamination and/or infection as well as entry of air into the insulin reservoir and leakage, of the insulin, which can cause inaccurate dosing. Needles must not be reused.



The pen cap should be replaced on the pen.

Arthrotec 50 is contraindicated in:



- Patients with active peptic ulcer/haemorrhage or perforation or who have active GI bleeding or other active bleedings e.g. cerebrovascular bleedings.



- Pregnant women and in women planning a pregnancy.



- Patients with a known hypersensitivity to diclofenac, aspirin, other NSAIDs, misoprostol, other prostaglandins, or any other ingredient of the product.



- Patients in whom attacks of asthma, urticaria or acute rhinitis are precipitated by aspirin or other non-steroidal anti-inflammatory agents.



- Treatment of peri-operative pain in the setting of coronary bypass graft (CABG) surgery.



- Patients with severe renal and hepatic failure.



- Patients with severe heart failure.



4.4 Special Warnings And Precautions For Use



Warnings



The use of diclofenac/misoprostol with concomitant NSAIDs including COX-2 inhibitors should be avoided.



Use in pre-menopausal women (see also section 4.3))



Arthrotec 50 should not be used in pre-menopausal women unless they use effective contraception and have been advised of the risks of taking the product if pregnant (see section 4.6). The label will state: 'Not for use by pre-menopausal women unless using effective contraception'.



Precautions



Undesirable effects may be minimised by using the lowest effective dose for the shortest duration necessary to control symptoms (see section 4.2, and GI and cardiovascular risks below).



Renal/Cardiac/Hepatic



In patients with renal, cardiac or hepatic impairment caution is required since the use of NSAIDs may result in deterioration of renal function. In the following conditions Arthrotec 50 should be used only in exceptional circumstances and with close clinical monitoring: advanced cardiac failure, advanced kidney failure, advanced liver disease, severe dehydration.



Diclofenac metabolites are eliminated primarily by the kidneys (see section 5.2). The extent to which the metabolites may accumulate in patients with renal failure has not been studied. As with other NSAIDs, metabolites of which are excreted by the kidney, patients with significantly impaired renal function should be more closely monitored.



In rare cases, NSAIDs, including diclofenac/misoprostol, may cause interstitial nephritis, glomerulitis, papillary necrosis and the nephrotic syndrome. NSAIDs inhibit the synthesis of renal prostaglandin which plays a supportive role in the maintenance of renal perfusion in patients whose renal blood flow and blood volume are decreased. In these patients, administration of an NSAID may precipitate overt renal decompensation, which is typically followed by recovery to pretreatment state upon discontinuation of NSAID therapy. Patients at greatest risk of such a reaction are those with congestive heart failure, liver cirrhosis, nephrotic syndrome and overt renal disease. Such patients should be carefully monitored while receiving NSAID therapy.



Appropriate monitoring and advice are required for patients with a history of hypertension and/or mild to moderate congestive heart failure as fluid retention and oedema have been reported in association with NSAID therapy.



As with all NSAIDS, diclofenac/misoprostol can lead to the onset of new hypertension or worsening of pre-existing hypertension, either of which may contribute to the increased incidence of cardiovascular events. NSAIDs, including diclofenac/misoprostol, should be used with caution in patients with hypertension. Blood pressure should be monitored closely during the initiation of therapy with diclofenac/misoprostol and throughout the course of therapy.



Patients with uncontrolled hypertension, congestive heart failure, established ischaemic heart disease, peripheral arterial disease, and/or cerebrovascular disease should only be treated with diclofenac after careful consideration. Similar consideration should be made before initiating longer-term treatment of patients with risk factors for cardiovascular events (e.g. hypertension, hyperlipidaemia, diabetes mellitus, smoking).



Clinical trial and epidemiological data suggest that use of diclofenac, particularly at high dose (150mg daily) and in long term treatment may be associated with a small increased risk of serious arterial thrombotic events (for example myocardial infarction or stroke).



Physicians and patients should remain alert for the development of such events, even in the absence of previous cardiovascular symptoms. Patients should be informed about the signs and/or symptoms of serious cardiovascular toxicity and the steps to take if they occur (see section 4.3).



Blood system/Gastrointestinal



NSAIDs, including diclofenac/misoprostol, can cause serious gastrointestinal (GI) adverse events including inflammation, bleeding, ulceration, and perforation of the stomach, small intestine, or large intestine, which can be fatal. When GI bleeding or ulceration occurs in patients receiving diclofenac/misoprostol, the treatment should be withdrawn. These events can occur at any time during treatment, with or without warning symptoms or in patients with a previous history of serious GI events.



Patients most at risk of developing these types of GI complications with NSAIDs are those treated at higher doses, the elderly, patients with cardiovascular disease, patients using concomitant aspirin, or patients with a prior history of, or active, gastrointestinal disease, such as ulceration, GI bleeding or inflammatory conditions.



Therefore, diclofenac/misoprostol should be used with caution in these patients and commence on treatment at the lowest dose available (see section 4.3).



Patients with a history of GI toxicity, particularly when elderly, should report any unusual abdominal symptoms (especially GI bleeding) particularly in the initial stages of treatment. Caution should be advised in patients receiving concomitant medicines which could increase the risk of ulceration or bleeding, such as oral corticosteroids, anticoagulants such as warfarin, selective serotonin-reuptake inhibitors or anti-platelet agents such as aspirin (see section 4.5).



Arthrotec 50, in common with other NSAIDs, may decrease platelet aggregation and prolong bleeding time. Extra supervision is recommended in haematopoietic disorders or in conditions with defective coagulation or in patients with a history of cerebrovascular bleeding.



Caution is required in patients suffering from ulcerative colitis or Crohn's Disease as these conditions may be exacerbated (see section 4.8).



Care should be taken in elderly patients and in patients treated with corticosteroids, other NSAIDs, or anti-coagulants (see section 4.5).



Skin Reactions



Serious skin reactions, some of them fatal, including exfoliative dermatitis, Stevens-Johnson syndrome, and toxic epidermal necrolysis, have been reported very rarely in association with the use of NSAIDs, including diclofenac/misoprostol (see section 4.8). Patients appear to be at highest risk for these events early in the course of therapy, the onset of the event occurring in the majority of cases within the first month of treatment. Diclofenac/misoprostol should be discontinued at the first appearance of skin rash, mucosal lesions, or any other sign of hypersensitivity



• Hypersensitivity



NSAIDs may precipitate bronchospasm in patients suffering from, or with a history of, bronchial asthma or allergic disease.



Long-term treatment



All patients who are receiving long-term treatment with NSAIDs should be monitored as a precautionary measure (e.g. renal, hepatic function and blood counts). During long-term, high dose treatment with analgesic/anti-inflammatory drugs, headaches can occur which must not be treated with higher doses of the medicinal product.



Arthrotec may mask fever and thus an underlying infection.



Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



NSAIDs may attenuate the natriuretic efficacy of diuretics due to inhibition of intrarenal synthesis of prostaglandins. Concomitant treatment with potassium-sparing diuretics may be associated with increased serum potassium levels, hence serum potassium should be monitored.



Because of their effect on renal prostaglandins, cyclo-oxygenase inhibitors such as diclofenac can increase the nephrotoxicity of ciclosporin. There is a possible increased risk of nephrotoxicity when NSAIDs are given with tacrolimus.



Steady state plasma lithium and digoxin levels may be increased and ketoconazole levels may be decreased.



Pharmacodynamic studies with diclofenac have shown no potentiation of oral hypoglycaemic and anticoagulant drugs. However as interactions have been reported with other NSAIDs, caution and adequate monitoring are, nevertheless advised (see statement on platelet aggregation in Precautions).



Because of decreased platelet aggregation caution is also advised when using Arthrotec 50 with anti-coagulants. NSAIDs may enhance the effects of anti-coagulants, such as warfarin, antiplatelet agents, such as aspirin, and serotonin re-uptake inhibitors (SSRIs) thereby increasing the risk of gastrointestinal bleeding (see section 4.4).



Cases of hypo and hyperglycaemia have been reported when diclofenac was associated with antidiabetic agents.



Caution is advised when methotrexate is administered concurrently with NSAIDs because of possible enhancement of its toxicity by the NSAID as a result of increase in methotrexate plasma levels.



Concomitant use with other NSAIDs or with corticosteroids may increase the frequency of side effects generally.



Anti-hypertensives including diuretics, angiotensin-converting enzyme (ACE) inhibitors and angiotensin II antagonists (AIIA): NSAIDs can reduce the efficacy of diuretics and other antihypertensive drugs.



In patients with impaired renal function (e.g. dehydrated patients or elderly patients with compromised renal function), the co-administration of an ACE inhibitor or an AIIA with a cyclo-oxygenase inhibitor can increase the deterioration of the renal function, including the possibility of acute renal failure, which is usually reversible. The occurrence of these interactions should be considered in patients taking diclofenac/misoprostol with an ACE inhibitor or an AIIA.



Antacids may delay the absorption of diclofenac. Magnesium-containing antacids have been shown to exacerbate misoprostol-associated diarrhoea.



Animal data indicate that NSAIDs can increase the risk of convulsions associated with quinolone antibiotics. Patients taking NSAIDs and quinolones may have an increased risk of developing convulsions.



NSAIDs should not be used for 8-12 days after mifepristone administration as NSAIDs can reduce the effect of mifepristone.



4.6 Pregnancy And Lactation



Pregnancy



Arthrotec 50 is contraindicated in pregnant women and in women planning a pregnancy because misoprostol induces uterine contractions and is associated with abortion, premature birth, and foetal death. Use of misoprostol has been associated with birth defects. Also diclofenac may cause premature closure of the ductus arteriosus.



Women of childbearing potential should not be started on diclofenac/misoprostol until pregnancy is excluded, and should be fully counseled on the importance of adequate contraception while undergoing treatment. If pregnancy is suspected, use of the product should be discontinued.



Lactation



Misoprostol is rapidly metabolised in the mother to misoprostol acid, which is biologically active and is excreted in breast milk. Diclofenac is excreted in breast milk in very small quantities. In general, the potential effects on the infant from any exposure to misoprostol and its metabolites via breast feeding are unknown. However, diarrhoea is a recognised side effect of misoprostol and could occur in infants of nursing mothers. Arthrotec 50 should therefore not be administered to nursing mothers.



4.7 Effects On Ability To Drive And Use Machines



Patients who experience dizziness or other central nervous system disturbances while taking NSAIDs should refrain from driving or operating machinery.



4.8 Undesirable Effects



In the table below the incidence of adverse drug reactions reported in controlled clinical studies where Arthrotec was administered to more than 2000 patients are listed. Additionally, adverse drug reactions reported during post-marketing surveillance are whose frequency cannot be estimated from the available data, such as spontaneous reports, have been listed at frequency 'unknown'. The most commonly observed adverse events are gastrointestinal in nature.

Uterine perforation



1 Symptoms of aseptic meningitis (stiff neck, headache, nausea, vomiting, fever or impaired consciousness) have been reported during treatment with NSAIDs. Patients suffering from autoimmune disease (e.g. lupus erythematosus, mixed connective tissue disorders) seem to be more susceptible.



2 Diarrhoea is usually mild to moderate and transient and can be minimised by taking Arthrotec 50 with food and by avoiding the use of predominantly magnesium-containing antacids.



3 GI perforation or bleeding can sometimes be fatal, particularly in the elderly (see section 4.4).



4 Serious skin reactions, some of them fatal, have been reported very rarely (see section 4.4).



5 Especially in patients with hypertension or impaired renal function (see section 4.4).



Given the lack of precise and/or reliable denominator and numerator figures, the spontaneous adverse event reporting system through which post marketing safety data are collected does not allow for a medically meaningful frequency of occurrence of any undesirable effects.



With regard to the relative frequency of reporting of adverse reactions during post marketing surveillance, the undesirable effects at the gastrointestinal level were those received most frequently by the MAH (approximately 45% of all case reports in the company safety database) followed by cutaneous/hypersensitivity-type reactions, which is in agreement with the known side effects profile of the NSAIDs drug class.



Clinical trial and epidemiological data suggest that use of diclofenac, particularly at high doses (150 mg daily) and in long term treatment may be associated with a small increased risk of arterial thrombotic events (for example myocardial infarction or stroke) (see section 4.4).



4.9 Overdose



The toxic dose of Arthrotec 50 has not been determined and there is no experience of overdosage. Intensification of the pharmacological effects may occur with overdosage. Management of acute poisoning with NSAIDs essentially consists of supportive and symptomatic measures. It is reasonable to take measures to reduce absorption of any recently consumed drug by forced emesis, gastric lavage or activated charcoal.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



Pharmacotherapeutic group (ATC code): M01BX



Arthrotec 50 is a non-steroidal, anti-inflammatory drug which is effective in treating the signs and symptoms of arthritic conditions.



This activity is due to the presence of diclofenac which has been shown to have anti-inflammatory and analgesic properties.



Arthrotec 50 also contains the gastroduodenal mucosal protective component misoprostol which is a synthetic prostaglandin E1 analogue that enhances several of the factors that maintain gastroduodenal mucosal integrity.



5.2 Pharmacokinetic Properties



The pharmacokinetic profiles of diclofenac and misoprostol administered as Arthrotec 50 are similar to the profiles when the two drugs are administered as separate tablets and there are no pharmacokinetic interactions between the two components.



Diclofenac sodium is completely absorbed from the gastrointestinal (GI) tract after fasting oral administration. Only 50 % of the absorbed dose is systemically available due to first pass metabolism. Peak plasma levels are achieved in 2 hours (range 1-4 hours), and the area-under-the plasma-concentration curve (AUC) is dose proportional within the range of 25 mg to 150 mg. The extent of diclofenac sodium absorption is not significantly affected by food intake.



The terminal half-life is approximately 2 hours. Clearance and volume of distribution are about 350 ml/min and 550 ml/kg, respectively. More than 99 % of diclofenac sodium is reversibly bound to human plasma albumin, and this has been shown not to be age dependent.



Diclofenac sodium is eliminated through metabolism and subsequent urinary and biliary excretion of the glucuronide and the sulfate conjugates of the metabolites. Approximately 65 % of the dose is excreted in the urine and 35 % in the bile. Less than 1 % of the parent drug is excreted unchanged.



Misoprostol is rapidly and extensively absorbed, and it undergoes rapid metabolism to its active metabolite, misoprostol acid, which is eliminated with an elimination t½ of about 30 minutes. No accumulation of misoprostol acid was found in multiple-dose studies, and plasma steady state was achieved within 2 days. The serum protein binding of misoprostol acid is less than 90 %. Approximately 70 % of the administered dose is excreted in the urine, mainly as biologically inactive metabolites.



5.3 Preclinical Safety Data



In co-administration studies in animals, the addition of misoprostol did not enhance the toxic effects of diclofenac. The combination was also shown not to be teratogenic or mutagenic. The individual components show no evidence of carcinogenic potential.



Misoprostol in multiples of the recommended therapeutic dose in animals has produced gastric mucosal hyperplasia. This characteristic response to E-series prostaglandins reverts to normal on discontinuation of the compound.
