Indication
Treatment of all patients with type 1 diabetes. Treatment of patients with type 2 diabetes who are not adequately controlled by diet and/ or oral hypoglycemic agents.For the initial stabilization of diabetes in patients with diabetic ketoacidosis, hyperosmolar non-ketotic syndrome and during periods of stress such as severe infections and major surgery in diabetic patients. Treatment of gestational diabetes.
Pharmacology
Insulin Human (rDNA) is human insulin made by recombinant DNA technology. It has the same structure and function as natural insulin. Insulin regulates the glucose metabolism and stimulates the ingestion and utilization of glucose by liver, muscle and fat tissue. It also lowers blood glucose by accelerating glycogenesis and inhibiting gluconeogenesis. Insulin Human (rDNA) 30/70 & Insulin Human (rDNA) 50/50 start action within 30 minutes after injection, reach peak level within 2-8 hours and last about 24 hours.
Dosage
The average range of total daily insulin requirement for maintenance therapy in type 1 diabetic patients lies between 0.5 and 1.0 IU/kg. In pre-pubertal children it usually varies from 0.7 to 1.0 IU/kg, whereas in insulin resistant cases, e.g. during puberty or due to obesity, the daily insulin requirement may be substantially higher. Initial dosages for type 2 diabetic patients are often lower, e.g. 0.3 to 0.6 IU/kg/day.The dosage form, the dosage and the administration time of the insulin are different due to the individual differences of each patient. In addition, the dosage is also affected by food, working style and exercising intensity. Therefore, patients should use the insulin under doctor's instruction.
Interaction
When using oral contraceptive drug, adrenal cortical hormone, thyroid hormone, etc., the drugs that can result in the rise of blood glucose; you might need to increase the amount of Insulin. When using drugs with hypoglycemic activities, salicylate, sulfanilamide and other anti-depressants, which will result in the decrease of blood glucose, the dosage of insulin should be reduced.
Contradiction
Hypoglycemia or the patients who have allergic reaction to insulin or any of the excipients.
Side Effect
Hypoglycemia is the most common adverse effect during insulin treatment and symptoms of hypoglycemia may occur suddenly. Few cases of the allergic reaction such as red and swollen or itching are reported. It usually disappears in a few days. In some instances, the allergy may be caused by other reasons rather than insulin, such as disinfectant and poor injection technique.
Pregnancy
There are no restrictions on treatment of diabetes with insulin during pregnancy, as insulin does not pass the placental barrier. Insulin treatment of the nursing mother presents no risk to the baby.
Precaution
Inadequate dosing or discontinuation especially in type 1 diabetes, may lead to hyperglycemia. Hypoglycemia 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 hypoglycemia.
Overdose
Excessive use of insulin may lead to hypoglycemia during the treatment. Slight to moderate hypoglycemia may suddenly occur. It is important to get immediate treatment when hypoglycemia occurs. If you have frequent hypoglycemia, you should consult your doctor to discuss possible changes in therapy, diet plans, and/or exercise programs to help you avoid hypoglycemia.
Storage
Store at 2?C - 8?C in a refrigerator. Do not freeze. In case of insulin for recent use need not be refrigerated, try to keep it in a cool place and keep away from heat and light. The insulin in use can be kept under the room temperature for a month.
