Isophane insulin rDNA.
Description
Insulatard Penfill/Insulatard Flexpen: Insulin human, rDNA (produced by recombinant DNA technology in Saccharomyces cerevisiae).
1 mL contains 100 IU of insulin human.
One cartridge and 1 pre-filled pen contains 3 mL equivalent to 300 IU.
One IU (International Unit) corresponds to 0.035 mg of anhydrous human insulin.
Insulatard is a suspension of isophane (NPH) insulin.
Excipients/Inactive Ingredients: Zinc chloride, glycerol, metacresol, phenol, disodium phosphate dihydrate, sodium hydroxide/hydrochloric acid (for pH adjustment), protamine sulphate and water for injections.
Action
Pharmacotherapeutic group: Drugs used in diabetes. Insulins and analogues for injection, intermediate-acting, insulin (human). ATC code: A10AC01.
Pharmacology: Pharmacodynamics: The blood glucose lowering effect of insulin is due to the facilitated uptake of glucose following binding of insulin to receptors on muscle and fat cells and to the simultaneous inhibition of glucose output from the liver.
Insulatard is a long-acting insulin.
Onset of action is within 1½ hours, reaches a maximum effect within 4 - 12 hours and the entire duration of action is approximately 24 hours.
Pharmacokinetics: Insulin in the blood stream has a half-life of a few minutes. Consequently, the time-action profile of an insulin preparation is determined solely by its absorption characteristics.
This process is influenced by several factors (e.g. insulin dosage, injection route and site, thickness of subcutaneous fat, type of diabetes). The pharmacokinetics of insulin products are therefore affected by significant intra- and inter-individual variation.
Absorption: The maximum plasma concentration of the insulin is reached within 2-18 hours after subcutaneous administration.
Distribution: No profound binding to plasma proteins, except circulating insulin antibodies (if present) has been observed.
Metabolism: Human insulin is reported to be degraded by insulin protease or insulin-degrading enzymes and possibly protein disulfide isomerase. A number of cleavage (hydrolysis) sites on the human insulin molecule have been proposed; none of the metabolites formed following the cleavage are active.
Elimination: The terminal half-life is determined by the rate of absorption from the subcutaneous tissue. The terminal half-life (t½) is therefore a measure of the absorption rather than of the elimination per se of insulin from plasma (insulin in the blood stream has a t½ of a few minutes). Trials have indicated a t½ of about 5-10 hours.
Toxicology: Preclinical safety data: Non-clinical data reveal no special hazard for humans based on conventional studies of safety pharmacology, repeated dose toxicity, genotoxicity, carcinogenic potential, toxicity to reproduction.
Indications/Uses
Treatment of diabetes mellitus.
Dosage/Direction for Use
Insulatard is a long-acting insulin and may be used alone or in combination with fast or rapid-acting insulin products.
Dosage: Dosage is individual and determined in accordance with the needs of the patient. The individual insulin requirement is usually between 0.3 and 1.0 IU/kg/day. The daily insulin requirement may be higher in patients with insulin resistance (e.g. during puberty or due to obesity) and lower in patients with residual, endogenous insulin production.
Dosage adjustment: Concomitant illness, especially infections and feverish conditions, usually increases the patient's insulin requirement. Concomitant diseases in the kidney, liver or affecting the adrenal, pituitary or thyroid gland can require changes in the insulin dose. Adjustment of dosage may also be necessary if patients change physical activity or their usual diet. Dosage adjustment may be necessary when transferring patients from one insulin preparation to another.
Administration: For subcutaneous use. Insulin suspensions are never to be administered intravenously.
Insulatard is administered subcutaneously in the thigh. If convenient, the abdominal wall, the gluteal region or the deltoid region may also be used.
Subcutaneous injection into the thigh results in a slower and less variable absorption compared to other injection sites. Injection into a lifted skin fold minimises the risk of unintended intramuscular injection. The needle should be kept under the skin for at least 6 seconds to make sure the entire dose is injected. Injection sites should always be rotated within the same region in order to reduce the risk of lipodystrophy.
Insulatard Penfill: Insulatard Penfill is designed to be used with Novo Nordisk delivery systems and NovoFine or NovoTwist needles.
Insulatard Flexpen: Insulatard Flexpen is a pre-filled pen designed to be used with NovoFine or NovoTwist disposable needles up to a lenght of 8 mm. Flexpen delivers 1-60 units in increments of 1 unit.
Insulatard Penfill and Insulatard Flexpen is accompanied by a package leaflet with detailed instructions for use to be followed.
Overdosage
A specific overdose of insulin cannot be defined, however, hypoglycaemia may develop over sequential stages if too high doses relative to the patient's requirement are administered: Mild hypoglycaemic episodes can be treated by oral administration of glucose or sugary products. It is therefore recommended that the diabetic patient always carries sugar containing products.
Severe hypoglycaemic episodes, where the patient has become unconscious, can be treated with glucagon (0.5 to 1 mg) given intramuscularly or subcutaneously by a trained person, or with glucose given intravenously by a healthcare professional. Glucose must be given intravenously, if the patient does not respond to glucagon within 10 to 15 minutes.
Upon regaining consciousness, administration of an oral carbohydrate is recommended for the patient in order to prevent a relapse.
Contraindications
Hypersensitivity to the active substance or to any of the excipients.
Special Precautions
Inadequate dosage or discontinuation of treatment, especially in type 1 diabetes, may lead to hyperglycaemia.
Usually, the first symptoms of hyperglycaemia set in gradually, over a period of hours or days. They include thirst, increased frequency of urination, nausea, vomiting, drowsiness, flushed dry skin, dry mouth, loss of appetite as well as acetone odour of breath.
In type 1 diabetes, untreated hyperglycaemic events eventually lead to diabetic ketoacidosis, which is potentially lethal.
Hypoglycaemia may occur if the insulin dose is too high in relation to the insulin requirement.
Omission of a meal or unplanned, strenuous physical exercise may lead to hypoglycaemia.
Patients, whose blood glucose control is greatly improved e.g. by intensified insulin therapy, may experience a change in their usual warning symptoms of hypoglycaemia and should be advised accordingly.
Usual warning symptoms may disappear in patients with longstanding diabetes.
Transferring a patient to another type or brand of insulin should be done under strict medical supervision. Changes in strength, brand (manufacturer), type, origin (human insulin, insulin analogue) and/or method of manufacture may result in a need for a change in dosage. Patients transferred to Insulatard from another type of insulin may require an increased number of daily injections or change in dosage from that used with their usual insulin products. If an adjustment is needed when switching the patient to Insulatard, it may occur with the first dose or during the first few weeks or months.
As with any insulin therapy, injection site reactions may occur and include pain, redness, hives, inflammation, bruising, swelling and itching. Continuous rotation of the injection site within a given area may help to reduce or prevent these reactions. Reactions usually resolve in a few days to a few weeks. On rare occasions, injection site reactions may require discontinuation of Insulatard.
When patients are transferred between different types of insulin medicinal products, the early warning symptoms of hypoglycaemia may change or become less pronounced than those experienced with their previous insulin.
Before travelling between different time zones, the patient should be advised to consult the physician, since this may mean that the patient has to take insulin and meals at different times.
Insulin suspensions are not to be used in insulin infusion pumps.
Combination of thiazolidinediones and insulin medicinal products: Cases of congestive heart failure have been reported when thiazolidinediones were used in combination with insulin, especially in patients with risk factors for development of congestive heart failure.
Effects on ability to drive and use machines: The patient's ability to concentrate and react may be impaired as a result of hypoglycaemia. 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 while driving. This is particularly important in those who have reduced or absent awareness of the warning signs of hypoglycaemia or have frequent episodes of hypoglycaemia. The advisability of driving should be considered in these circumstances.
Use In Pregnancy & Lactation
There are no restrictions on treatment of diabetes with insulin during pregnancy, as insulin does not pass the placental barrier.
Both hypoglycaemia and hyperglycaemia, which can occur in inadequately controlled diabetes therapy, increase the risk of malformations and death in utero. Intensified blood glucose control and monitoring of pregnant women with diabetes are recommended throughout pregnancy and when contemplating pregnancy.
Insulin requirements usually fall in the first trimester and increase subsequently during the second and third trimesters. After delivery, insulin requirements normally return rapidly to pre-pregnancy values.
There is no restriction on treatment with Insulatard during breast-feeding.
Insulin treatment of the nursing mother presents no risk to the baby. However, the Insulatard dosage, diet or both may need to be adjusted.
Adverse Reactions
Summary of the safety profile: The most frequently reported adverse reaction during treatment is hypoglycaemia. In clinical trials and during marketed use, the frequencies of hypoglycaemia vary with patient population, dose regimens and level of glycaemia control, please see Description of selected adverse reactions as follows.
At the beginning of the insulin treatment, refraction anomalies, oedema and injection site reactions (pain, redness, hives, inflammation, bruising, swelling and itching at the injection site) may occur. These reactions are usually of transitory nature. Fast improvement in blood glucose control may be associated with acute painful neuropathy, which is usually reversible. Intensification of insulin therapy with abrupt improvement in glycaemic control may be associated with temporary worsening of diabetic retinopathy, while long-term improved glycaemic control decreases the risk of progression of diabetic retinopathy.
Tabulated list of adverse reactions: Adverse reactions listed as follows are based on clinical trial data and classified according to MedDRA frequency and System Organ Class. Frequency categories are defined according to the following convention: Very common (≥1/10); common (≥1/100 to <1/10); uncommon (≥1/1,000 to <1/100); rare (≥1/10,000 to <1/1,000); very rare (<1/10,000); not known (cannot be estimated from the available data).

Description of selected adverse reactions: Anaphylactic reactions: The occurrence of generalised hypersensitivity reactions (including generalised skin rash, itching, sweating, gastrointestinal upset, angioneurotic oedema, difficulties in breathing, palpitation, reduction in blood pressure and fainting/loss of consciousness) is very rare but can potentially be life threatening.
Hypoglycaemia: The most frequently reported adverse reaction is hypoglycaemia. It may occur if the insulin dose is too high in relation to the insulin requirement. Severe hypoglycaemia may lead to unconsciousness and/or convulsions and may result in temporary or permanent impairment of brain function or even death. The 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.
Lipodystrophy: Lipodystrophy is reported as uncommon. Lipodystrophy may occur at the injection site.
Drug Interactions
A number of medicinal products are known to interact with the glucose metabolism.
The following substances may reduce the patient's insulin requirement: Oral anti-diabetic products, monoamine oxidase inhibitors (MAOI), non-selective beta-blocking agents, angiotensin converting enzyme (ACE) inhibitors, salicylates, anabolic steroids and sulphonamides.
The following substances may increase the patient's insulin requirement: Oral contraceptives, thiazides, glucocorticoids, thyroid hormones, sympathomimetics, growth hormone and danazol.
Beta-blocking agents may mask the symptoms of hypoglycaemia and delay recovery from hypoglycaemia.
Octreotide/lanreotide may either increase or decrease the insulin requirement.
Alcohol may intensify or reduce the hypoglycaemic effect of insulin.

Patient Counseling Information
Insulatard suspension for injection in Penfill: Do not use Insulatard: In insulin infusion pumps.
If you are allergic (hypersensitive) to human insulin or any of the other ingredients in Insulatard.
If you suspect hypoglycaemia (low blood sugar) is starting.
If the cartridge or the device containing the cartridge is dropped, damaged or crushed. If it has not been stored correctly or been frozen.
If the resuspended insulin does not appear uniformly white and cloudy.
Before using Insulatard: Check the label to make sure it is the right type of insulin.
Always check the cartridge, including the rubber stopper. Do not use it if any damage is seen or if there is a gap between the rubber stopper and the white label brand. Take it back to your pharmacy. See your delivery system manual for further instructions.
Always use a new needle for each injection to prevent contamination.
Needles and Insulatard Penfill must not be shared.
How to use this insulin: Insulatard is administered by injection under the skin (subcutaneously). Never inject your insulin directly into a vein or muscle. Always vary the sites you inject within the same region, to reduce the risk of developing lumps or skin pitting. The best places to give yourself an injection are: your buttocks; the front of your thighs or upper arms.
Resuspending the insulin: Resuspending is easier when the insulin has reached room temperature. Before you put the Penfill cartridge into the insulin delivery system, move it up and down between positions a and b and back (see the picture) so that the glass ball moves from one end of the cartridge to the other at least 20 times. Repeat this movement at least 10 times before each injection. The movement must always be repeated until the liquid appears uniformly white and cloudy. Complete the other stages of injection without delay.
Check there are at least 12 units of insulin left in the cartridge to allow even resuspending. If there are less than 12 units left, use a new one.
How to inject this insulin: Inject the insulin under the skin. Use the injection technique advised by your doctor or nurse and as described in your delivery system manual.
Keep the needle under your skin for at least 6 seconds. Keep the push-button fully depressed until the needle has been withdrawn. This will ensure correct delivery and limit possible flow of blood into the needle or insulin reservoir.
After each injection be sure to remove and discard the needle and store Insulatard without the needle attached. Otherwise the liquid may leak out which can cause inaccurate dosing.
Do not refill Insulatard Penfill.
Penfill cartridges are designed to be used with Novo Nordisk insulin delivery systems and NovoFine or NovoTwist needles. If you are treated with Insulatard Penfill and another insulin Penfill cartridge, you should use two insulin delivery systems, one for each type of insulin.
As a precautionary measure, always carry a spare insulin delivery system in case your Penfill is lost or damaged.
Insulatard suspension for injection in pre-filled pen:
Your FlexPen is a unique dial-a-dose insulin pen. You can select doses from 1 to 60 units in increments of 1 unit. FlexPen is designed to be used with NovoFine or NovoTwist disposable needles up to a length of 8 mm. As a precautionary measure, always carry a spare insulin delivery device in case the FlexPen is lost or damaged.
Maintenance: Your FlexPen is designed to work accurately and safely. It must be handled with care. If it is dropped or crushed, there is a risk of damage and leakage of insulin.
You can clean the exterior of the FlexPen by wiping it with a medicinal swab. Do not soak it, wash or lubricate it as it may damage the pen.
Do not refill your Insulatard FlexPen.
Preparing the Insulatard FlexPen: Check the label to make sure that the Insulatard FlexPen contains the correct type of insulin. Before the first injection with a new FlexPen, you must resuspend the insulin: A. Let the insulin reach room temperature before you use it. This makes it easier to resuspend. Pull off the pen cap.
B. Move the pen up and down twenty times, so the glass ball moves from one end of the cartridge to the other. Repeat until the liquid appears uniformly white and cloudy.For every following injection move the pen up and down at least 10 times until the liquid appears uniformly white and cloudy.
After the patient have resuspended the insulin, complete all the following steps of injection without delay.
Always check there are at least 12 units of insulin left in the cartridge to allow resuspension. If there are less than 12 units left, use a new FlexPen.
Attaching a needle: C. Remove the protective tab from a new disposable needle.
Screw the needle straight and tightly onto the FlexPen.
D. Pull off the big outer needle cap and keep it for later.
E. Pull off the inner needle cap and dispose of it.
Always use a new needle for each injection to prevent contamination.
Be careful not to bend or damage the needle before use.
To reduce the risk of unexpected needle sticks, never put the inner needle cap back on when the patient have removed it from the needle.
Checking the insulin flow: Prior to each injection, small amounts of air may collect in the cartridge during normal use. To avoid injection of air and ensure proper dosing: F. Turn the dose selector to select 2 units.
G. Hold the FlexPen with the needle pointing upwards and tap the cartridge gently with a finger a few times to make any air bubbles collect at the top of the cartridge.
H. Keeping the needle upwards, press the push-button all the way in. The dose selector returns to 0.
A drop of insulin should appear at the needle tip. If not, change the needle and repeat the procedure no more than 6 times.
If a drop of insulin still does not appear, the pen is defective, and you must use a new one.
Selecting the dose: Check that the dose selector is set at 0: I. Turn the dose selector to select the number of units you need to inject.
The dose can be corrected either up or down by turning the dose selector in either direction until the correct dose lines up with the pointer. When turning the dose selector, be careful not to push the push-button as insulin will come out.
You cannot select a dose larger than the number of units left in the cartridge.
Do not use the residual scale to measure your dose of insulin.
Making the injection: J. Insert the needle into your skin. Use the injection technique shown by your doctor or nurse: Inject the dose by pressing the push-button all the way in until 0 lines up with the pointer. Be careful only to push the push-button when injecting. Turning the dose selector will not inject insulin.
K. Keep the push-button fully depressed after the injection until the needle has been withdrawn from the skin. The needle must remain under the skin for at least 6 seconds. This will ensure that the full dose has been injected.
L. Lead the needle into the big outer needle cap without touching the big outer needle cap. When the needle is covered, carefully push the big outer needle cap completely on and then unscrew the needle.
Dispose of it carefully and put the pen cap back on.
Always remove the needle after each injection and store your FlexPen without the needle attached. Otherwise the liquid may leak out which can cause inaccurate dosing.
Caregivers should be most careful when handling used needles to avoid needle sticks.
Dispose of the used FlexPen carefully without the needle attached.
Needles and Insulatard FlexPen must not be shared.
