Indications/Uses
For the treatment of patients with diabetes mellitus who require insulin for the maintenance of glucose homeostasis.
Dosage/Direction for Use
Posology: The dosage should be determined by the physician, according to the requirement of the patient.
Pediatric population: No data are available.
Method of administration: Insulin Human (rDNA)(Humulin R) should be given by subcutaneous injection. It may also be administered intravenously.
Subcutaneous administration should be in the upper arms, thighs, buttocks or abdomen. Use of injection sites should be rotated so that the same site is not used more than approximately once a month.
Care should be taken when injecting any Insulin Human (Humulin) preparation to ensure that a blood vessel has not been entered. After any insulin injection, the injection site should not be massaged. Patients must be educated to use proper injection techniques.
Insulin Human (rDNA) (Humulin N) may be administered in combination with Insulin Human (rDNA) (Humulin R) (See Special precautions for disposal and other handling: Instructions for use and handling: Mixing of Insulins under Cautions for Usage).

Overdosage
Insulin has no specific overdose definitions, because serum glucose concentrations are a result of complex interactions between insulin levels, glucose availability and other metabolic processes. Hypoglycemia may occur as a result of an excess of insulin relative to food intake and energy expenditure.
Hypoglycemia may be associated with listlessness, confusion, palpitations, headache, sweating and vomiting.
Mild hypoglycemic episodes will respond to oral administration of glucose or sugar products.
Correction of moderately severe hypoglycemia can be accomplished by intramuscular or subcutaneous administration of glucagon, followed by oral carbohydrate when the patient recovers sufficiently. Patients who fail to respond to glucagon must be given glucose solution intravenously.
If the patient is comatose, glucagon should be administered intramuscularly or subcutaneously. However, glucose solution must be given intravenously, if glucagon is not available or if the patient fails to respond to glucagon. The patient should be given a meal as soon as consciousness is recovered.
Sustained carbohydrate intake and observation may be necessary because hypoglycemia may occur after apparent clinical recovery.

Special Precautions
Transferring a patient to another type or brand of insulin should be done under strict medical supervision. Changes in strength, brand (manufacturer), type (soluble, isophane, mixture), species (animal, human, human insulin analogue), and/or method of manufacture (recombinant DNA versus animal-source insulin) may result in the need for a change in dosage.
Some patients taking human insulin may require a change in dosage from that used with animal- source insulins. If an adjustment is needed, it may occur with the first dose or during the first several weeks or months.
A few patients who experienced hypoglycemic reactions after transfer to human insulin have reported that the early warning symptoms were less pronounced or different from those experienced with their previous animal insulin. Patients whose blood glucose is greatly improved, e.g. by intensified insulin therapy, may lose some or all of the warning symptoms of hypoglycemia and should be advised accordingly. Other conditions which may make the early warning symptoms of hypoglycemia different or less pronounced include long duration of diabetes, diabetic nerve disease, or medications such as beta blockers. Uncorrected hypoglycemic and hyperglycemic reactions can cause loss of consciousness, coma or death.
The use of dosages which are inadequate or discontinuation of treatment, especially in insulin- dependent diabetics, may lead to hyperglycemia and diabetic ketoacidosis; conditions which are potentially lethal.
Treatment with human insulin may cause formation of antibodies, but titres of antibodies are lower than those to purified animal insulin.
Insulin requirements may change significantly in diseases of the adrenal, pituitary or thyroid glands and in the presence of renal or hepatic impairment.
Insulin requirements may be increased during illness or emotional disturbances.
Adjustment of insulin dosage may also be necessary if patients change their level of physical activity or change their usual diet.
Combination of human insulin 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 human insulin is considered. If the combination is used, patients should be observed for signs and symptoms of heart failure, weight gain and edema. Pioglitazone should be discontinued, if any deterioration in cardiac symptoms occurs.
Excipients: This medicinal product contains less than 1 mmol sodium (23 mg) per dose, i.e., essentially "sodium- free".
Effects on ability to drive and use machines: The patient's ability to concentrate and react may be impaired as a result of hypoglycemia. 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 hypoglycemia whilst driving, this is particularly important in those who have reduced or absent awareness of the warning signs of hypoglycemia or have frequent episodes of hypoglycemia. The advisability of driving should be considered in these circumstances.

Use In Pregnancy & Lactation
It is essential to maintain good control of the insulin treated (insulin-dependent or gestational diabetes) patient throughout pregnancy. Insulin requirements usually fall during the first trimester and increase during the second and third trimesters. Patients with diabetes should be advised to inform their doctors if they are pregnant or are contemplating pregnancy.
Careful monitoring of glucose control, as well as general health, is essential in pregnant patients with diabetes.
Patients with diabetes who are lactating may require adjustments in insulin dose and/or diet.

Adverse Reactions
Hypoglycemia is the most frequent undesirable effect of insulin therapy that a patient with diabetes may suffer. Severe hypoglycemia may lead to loss of consciousness, and in extreme cases, death. No specific frequency for hypoglycemia is presented, since hypoglycemia is a result of both the insulin dose and other factors e.g. a patient's level of diet and exercise.
Local allergy in patients is common (≥1/100 to < 1/10). Redness, swelling, and itching can occur at the site of insulin injection. This condition usually resolves in a few days to a few weeks. In some instances, local reactions may be related to factors other than insulin, such as irritants in the skin cleansing agent or poor injection technique.
Systemic allergy, which is very rare (< 1/10,000) but potentially more serious, is a generalized allergy to insulin. It may cause rash over the whole body, shortness of breath, wheezing, reduction in blood pressure, fast pulse, or sweating. Severe cases of generalized allergy may be life-threatening. In the rare event of a severe allergy to Regular Insulin Human (Humulin R), treatment is required immediately. A change of insulin or desensitization may be required.
Lipodystrophy at the injection site is uncommon (≥1/1,000 to < 1/100).
Cases of edema have been reported with insulin therapy, particularly if previous poor metabolic control is improved by intensified insulin therapy.
Reporting of suspected adverse reactions: Reporting suspected adverse reactions after authorization 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.

Drug Interactions
A number of medicinal products are known to interact with glucose metabolism and therefore the physician should be consulted when using other medications in addition to human insulin (see Precautions). The physician must therefore take possible interactions into account and should always ask his patients about any medicinal products they take.
Insulin requirements may be increased by substances with hyperglycemic activity, such as glucocorticoids, thyroid hormones, growth hormone, danazol, beta2-sympathomimetics (such as ritodrine, salbutamol, terbutaline), thiazides.
Insulin requirements may be reduced in the presence of substances with hypoglycemic activity, such as oral hypoglycemics (OHA), salicylates (for example, acetylsalicylic acid), certain antidepressants (monoamine oxidase inhibitors), certain angiotensin converting enzyme (ACE) inhibitors (captopril, enalapril), angiotensin II receptor blockers, non-selective beta-blocking agents and alcohol.
Somatostatin analogues (octreotide, lanreotide) may both decrease or increase insulin dose requirements.

Caution For Usage
Special precautions for disposal and other handling: Do not reuse needles. Dispose of the needle in a responsible manner. Needles must not be shared. Vials can be used until empty, then properly discard. Any unused medicinal product or waste material should be disposed of in accordance with local requirements.
Instructions for use and handling: A solution for injection in a 10 mL vial to be used in conjunction with an appropriate syringe (100 IU/mL markings).
a) Preparing a dose: Vials containing Insulin Human (rDNA) (Humulin R) formulation do not require resuspension and should only be used if it is clear, colorless, with no solid particles visible and if it is of water-like appearance.
Mixing of insulins: The shorter acting insulin should be drawn into the syringe first, to prevent contamination of the vial by the longer acting preparation. It is advisable to inject directly after mixing. However, if a delay is necessary, a consistent routine must be followed.
Alternatively, a separate syringe or, separate cartridges of Insulin Human (rDNA) (Humulin R) and Insulin Human (rDNA) (Humulin N) can be used for administration of the correct amount of each formulation.
Prepare syringe prior to injection, as directed by the doctor or diabetes specialist nurse. Use an insulin syringe marked for the strength of insulin being administered.
b) Injecting a dose: Inject the correct dose of insulin, as directed by the doctor or diabetes specialist nurse. Use of the injection sites should be rotated so that the same is not used more than approximately once a month.
Incompatibilities: Insulin Human (rDNA) (Humulin R) preparations should not be mixed with insulins produced by other manufacturers or with animal insulin preparations.

Action
Pharmacotherapeutic group: Insulins and analogues for injection, fast-acting. ATC code: A10A B01.
Pharmacology: Pharmacodynamics: Insulin Human (rDNA) (Humulin R) is a rapidly acting insulin preparation.
The prime activity of insulin is the regulation of glucose metabolism. In addition insulin has several anabolic and anti-catabolic actions on a variety of different tissues. Within muscle tissue this includes increasing glycogen, fatty acid, glycerol and protein synthesis and amino acid uptake, while decreasing glycogenolysis, gluconeogenesis, ketogenesis, lipolysis, protein catabolism and amino acid output.
The typical activity profile (glucose utilization curve) following subcutaneous injection is illustrated as follows by the heavy line. Variations that a patient may experience in timing and/or intensity of insulin activity are illustrated by the shaded area. Individual variability will depend on factors such as size of dose, site of injection temperature and physical activity of the patient. (See Figure.)

Pharmacokinetics: The pharmacokinetics of insulin do not reflect the metabolic action of that hormone. Therefore, it is more appropriate to examine glucose utilization curves when considering the activity of insulin.
Toxicology: Preclinical safety data: Insulin Human (rDNA) (Humulin R) is human insulin produced by recombinant technology. No serious events have been reported in subchronic toxicology studies. Human insulin was not mutagenic in a series of in vitro and in vivo genetic toxicity assays.
