[New Insulins for Type 1 Diabetes treatment]

Insulin therapy is complex in pediatric patients because they present greater variations in insulin requirements. Traditional insulins have limitations related to time of onset of action and duration of effect, which has led to the development of new insulins, seeking to reduce chronic complications, severe or nocturnal hypoglycemia, and to improve adherence to therapy. This review updates the information on new insulins, their mechanisms of action and the benefits they provide in the treatment of diabetes. Insulin analogues attempt to mimic the physiological secretion of the hormone, including time of action and duration of effect. The most used prandial analogs are the so-called rapid-acting insulins, including Faster Aspartic and the new basal insulins, glargine U300 and degludec, which have a prolonged action of more than 24 hours and therefore require a daily dose. New technologies under development include biosimilar insulins such as the glargine biosimilar, already available in the clinic. New formulations are being developed for the future, as well as novel ways of dispersing them, mimicking the action of pancreatic cells, which will allow a more physiological and personalized management of the disease.
