Suspension for injection.
A white suspension
The treatment of insulin dependent diabetes mellitus.
May be used for diabetics requiring a depot insulin of intermediate duration.
To be determined by the physician according to the needs of the patient.
Method of administration
Usually administered subcutaneously but where necessary it may be given intramuscularly in which case onset is more rapid and overall duration shorter. It should not be given intravenously. Onset of action occurs within 2 hours after subcutaneous injection with an overall duration up to 24 hours. Maximum effect is exerted between 4-12 hours.
Hypurin® Porcine 30/70 Mix in cartridges is only suitable for subcutaneous injections from a reusable pen.
If administration by syringe is necessary, a vial should be used.
Injection sites should always be rotated within the same region in order to reduce the risk of lipodystrophy and cutaneous amyloidosis (see section 4.4 and 4.8).
Hypersensitivity to insulin or to any of the excipients listed in section 6.1.
In no circumstances must Hypurin® Porcine 30/70 Mix be given intravenously.
Hypoglycaemia: Susceptibility to hypoglycaemia may be increased by an inaccurate or excessive dosage of insulin, the omission of a meal by the patient or increased physical activity. Correct insulin administration and awareness of the symptoms of hypoglycaemia are essential to reduce the risk of hypoglycaemia (see section 4.9).
Blood or urinary glucose concentrations should be monitored and the urine tested for ketones by patients on insulin therapy.
Newly diagnosed diabetic patients may experience fluctuating insulin requirements during the first weeks, months or even years of treatment (the so-called 'honeymoon period').
Patients transferred to Hypurin® Porcine insulins from other commercially available preparations may require dosage adjustments.
The warning symptoms of hypoglycaemia may be changed, be less pronounced or absent in certain risk groups who should be advised accordingly. These include patients:
- in whom glycaemic control is greatly improved, e.g. by intensified insulin therapy
- with a long history of diabetes
- who are elderly
- receiving concomitant treatment with certain medicinal products e.g. beta blockers or clonidine
- who have experienced repeated episodes of hypoglycaemia.
Elderly diabetic patients are more susceptible to episodes of severe, rapid onset hypoglycaemia.
Combination of Hypurin® insulins with pioglitazone: Cases of cardiac failure have been reported when thiazolidinediones are 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 Hypurin® 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.
Insulin requirements may increase during illness (this includes infection and accidental and surgical trauma), puberty or emotional upset.
Insulin resistance is frequently associated with lipid disorders, hypertension and ischaemic heart disease. Patients with insulin resistance usually require more than 200 units of insulin daily. Insulin resistance of the type manifested by greatly increased insulin requirements may be due to factors including antibody formation although some diseases, such as infections, endocrine hyperfunctional states (e.g. acromegaly, Cushing's syndrome, thyrotoxicosis) or stress can contribute to insulin resistance.
Insulin requirements may decrease with liver disease, disease of the adrenal, pituitary or thyroid glands and coeliac disease. In patients with severe renal impairment, insulin requirements may fall and dosage reduction may be necessary. The compensatory response to hypoglycaemia may also be impaired.
Insulin requirements may be increased in the premenstrual period but may be reduced during or after a menstrual cycle.
Insulin requirements are usually reduced but occasionally increased during periods of increased activity.
Increase in subcutaneous blood flow, brought about by factors such as a hot bath, sunbathing/sunbed or sauna may increase the rate of absorption of insulin and increase the risk of hypoglycaemia occurring.
Patients must be instructed to perform continuous rotation of the injection site to reduce the risk of developing lipodystrophy and cutaneous amyloidosis. There is a potential risk of delayed insulin absorption and worsened glycaemic control following insulin injections at sites with these reactions. A sudden change in the injection site to an unaffected area has been reported to result in hypoglycaemia. Blood glucose monitoring is recommended after the change in the injection site, and dose adjustment of antidiabetic medications may be considered.
Drugs that may increase the requirement for insulin
Diuretics: thiazide diuretics or loop diuretics
Thyroid hormone replacement therapy
Smoking may also antagonise the hypoglycaemic effect of insulin
Drugs that may decrease the requirement for insulin
Alcohol: moderate or large amounts of alcohol (more than 2 units per day for women and more than 3 units per day for men) can decrease the requirements for insulin and may lead to hypoglycaemic attacks. Episodic heavy drinking ('binge' drinking) carries a particularly high risk of hypoglycaemic episodes.
Analgesics: NSAIDS, or salicylates, particularly large doses of aspirin
Androgens: testosterone may enhance the hypoglycaemic effect of insulin
Concomitant use of insulin with quinidine may increase the risk of hypoglycaemia occurring.
Anti-depressants: monoamine oxidase inhibitors or fluoxetine.
Concomitant use of amitriptyline with insulin may lead to hypoglycaemia.
Antimalarials: concomitant use of insulin with antimalarials such as chloroquine or quinine may increase the risk of hypoglycaemia occurring.
Hormone antagonists: octreotide
Lipid-regulating drugs: fibrates
Pentoxifylline: the hypoglycaemic activity of insulin may be potentiated by concomitant administration of high-dose pentoxifylline injection.
Tetracyclines: tetracyclines such as oxytetracycline
Drugs that may increase or decrease the requirements for insulin
Antihypertensives: clonidine. Signs and symptoms of hypoglycaemia may be masked by clonidine.
Beta blockers: beta blockers. Some of the warning signs of insulin-induced hypoglycaemia may be masked.
Calcium channel blockers: nifedipine may occasionally impair glucose tolerance.
Lipid-regulating drugs: gemfibrozil
Antidiabetics: Thiazolidinediones (pioglitazone) may induce oedema and/or heart failure with higher rates of heart failure when used concomitantly with insulin (see section 4.4).
A decreased requirement for insulin may be observed in the early stages of pregnancy. However, in the second and third trimesters, insulin requirements may increase. Insulin requirements should therefore be assessed frequently by an experienced diabetic physician.
Maternal insulin requirements may decrease after delivery. As this decrease can be at an unpredictable rate, the maternal blood glucose should be closely monitored.
Congenital abnormality is more common in offspring of diabetic than non-diabetic women.
Caution should be exercised when prescribing to lactating women. Lactating women may require adjustments in insulin dose and diet.
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 whilst 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.
Immune system disorders:
Insulin hypersensitivity can occur with animal insulins, but appears less likely with purified insulins and there is minimal evidence that such effects occur with Hypurin insulins.
Neuropathic pain induced by rapid glycaemic control following insulin administration may occur.
Allergic reactions to phenol and m-cresol contained as preservative and to zinc and protamine may occur.
• Local hypersensitivity: Local allergic reactions to insulin such as pruritus, erythema and oedema may occur at the injection site.
• Generalised hypersensitivity: Generalised hypersensitivity may produce urticaria, rash, nausea, dyspnoea or wheezing and, in rare cases, anaphylactic reactions. Severe, angioedema is a rare adverse effect of insulin treatment occurring most often at the initiation of therapy.
Metabolism and nutrition disorders:
• Hypoglycaemia is the most common adverse effect associated with insulin therapy. For symptoms of hypoglycaemia, refer to section 4.9, Overdosage.
• Hypokalaemia may occur with insulin therapy.
• Insulin therapy may lead to weight gain.
Skin and subcutaneous tissue disorders:
Lipodystrophy and cutaneous amyloidosis (frequency not known) may occur at the injection site and delay local insulin absorption. Continuous rotation of the injection site within the given injection area may help to reduce or prevent these reactions (see section 4.4).
General disorders and administration site conditions:
Stinging or sensations of warmth or burning at the site of injection may also occur.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
Overdosage causes hypoglycaemia. Symptoms include yawning, hunger, pallor, restlessness, weakness, sweating, trembling, confusion, anxiety, nervousness, excitement, irritability, aggression, altered behaviour, deep respiration, cramps, headache, paraesthesia and/or numbness of the nose, mouth, fingers or toes, reduced consciousness, visual disturbance, including blurred vision and double vision, slurred speech, difficulty in finding words, difficulty in concentration, drowsiness, fatigue, convulsions, hemiplegia, paralysis, tachycardia and/or palpitations, myocardial ischaemia and cerebral oedema which, if untreated, will lead to collapse, coma and/or irreversible brain damage.
Hypokalaemia may also occur with insulin overdose.
Mild hypoglycaemia will respond to oral administration of glucose or sugar and rest.
Moderately severe hypoglycaemia can be treated by intramuscular, intravenous or subcutaneous injection of glucagon followed by oral carbohydrate when the patient is sufficiently recovered.
For patients who are comatose or who have failed to respond to glucagon injection an intravenous injection of strong Dextrose Injection BP should be given.
Pharmacotherapeutic group: Insulins and analogues for injection, intermediate-acting
ATC Code – A10AC03
Insulin output from the pancreas of a healthy person is about 50 units per day, which is sufficient to maintain the fasting blood sugar concentration in the range 0.8 ! 0.2mg/ml. In diabetes mellitus, the blood sugar rises in an uncontrolled manner. Parenterally administered insulin causes a fall in blood sugar concentration and increased storage of glycogen in the liver. In the diabetic it raises the respiratory quotient after a carbohydrate meal and prevents the formation of ketone bodies. The rise in blood sugar concentration caused by adrenaline and corticosteroids, glucagon and posterior pituitary extract is reversed by insulin.
Insulin is rapidly absorbed from subcutaneous tissue or muscle following injection.
Insulin is metabolised mainly in the liver and a small amount is excreted in the urine.
The plasma half-life is four to five minutes. The half-life after subcutaneous injection is about four hours and after intramuscular injection about two hours.
There are no preclinical data of relevance to the prescriber that are additional to that already included in other sections.
