Insulin is the hormone normally made in the pancreas that stimulates the flow of sugar - glucose - from the blood into the cells of the body. Glucose provides the cells with the energy they need to function.

There are two main groups of insulins used in the treatment of diabetes: human insulins and analog insulins, made by recombinant DNA technology.

The concentration of most insulins available in the United States is 100 units per milliliter. A milliliter is equal to a cubic centimeter. All insulin syringes are graduated to match this insulin concentration.

There are four categories of insulins depending on how quickly they start to work in the body after injection:
<UL><LI>Very rapid acting insulin
</LI><LI>Regular, or Rapid acting insulins
</LI><LI>Intermediate acting insulins
</LI><LI>Long acting insulin.</LI></UL>
There are four categories of insulins depending on how quickly they start to work in the body after injection:
  • Very rapid acting insulin

  • Long acting insulin.
<UL><LI>In addition, some insulins are marketed mixed together in different proportions to provide both rapid and long acting effects. Certain insulins can also be mixed together in the same syringe immediately prior to injection.</LI></UL>
