Insulin even be slightly over-corrected) by the end of the test. Even during digestion, in general, one or two hours following a meal, insulin release from the pancreas is not continuous, but oscillates with a period of 3–6 minutes, changing from generating a blood insulin concentration more than about 800 p mol/l to less than 100 pmol/l. This is thought to avoid downregulation of insulin receptors in target cells, and to assist the liver in extracting insulin from the blood. This oscillation is important to consider when administering insulin-stimulating medication, since it is the oscillating blood concentration of insulin release, which
Insulin (medication) shown no unequivocal advantages in clinical use of insulin analogues over more conventional insulin types. Choosing insulin type and dosage/timing should be done by an experienced medical professional working closely with the diabetic patient. The commonly used types of insulin are as follows. Includes the insulin analogues "aspart", "lispro", and "glulisine". These begin to work within 5 to 15 minutes and are active for 3 to 4 hours. Most insulins form hexamers, which delay entry into the blood in active form; these analog insulins do not but have normal insulin activity. Newer varieties are now pending regulatory approval in the
