After the discovery of insulin in the 1920´s, available insulin was from natural sources (animal pancreas) until human insulin was made available in the early 1980s. None of these insulins was ideal for injection under the skin. Now, new insulins, so-called rapid-acting analogue insulins, act more quickly than other forms of the hormone and are effective over a shorter period of time: insulin lispro and insulin aspart (with others to come). In this article, Thomas Kunt describes the characteristics of these new insulins with a special focus on meal-time glucose control in people with Type 1 and Type 2 diabetes.
