An Evolutionary Perspective on Basal Insulin in Diabetes Treatment: Role of Insulin Therapy In Diabetes.

The availability of human insulin and subsequently insulin analogs that more closely mimic the body's physiology have contributed to increased safety in patients with diabetes and a greater role in patients with T2DM. This greater role is supported by clear evidence that early use of insulin in T2DM results in long-term improvements in glycemic control and beta-cell function compared with oral agents.
