Insulin secretion is modified by other nutrients, circulating hormones and the autonomic nervous system, as well as local paracrine and autocrine signals. Autocrine signalling involves diffusible molecules that bind to receptors on the same cell from which they have been released.
Each drug can be classified into one or more drug classes. Insulin is a polypeptide hormone that is important for regulating the amount of glucose in the blood. It is produced in the pancreas by the beta cells of the islets of Langerhans. Insulin given by injection acts similar to endogenous insulin. There are more than 20 different types of insulin available for diabetes treatment in the United States.
