Insulin degludec: A novel ultra-long-acting basal insulin for use in Type 1 and 2 diabetes

The prevalence of diabetes, a chronic disease that currently poses a significant health burden in both developed and developing countries, is expected to increase significantly over the foreseeable future. In Type 1 diabetes, insulin replacement is absolutely imperative; in Type 2 diabetes, many patients will eventually require insulin replacement therapy to compensate for progressive β-cell failure and maintain blood glucose control. Even though currently available insulin analog preparations more closely mimic physiologic insulin needs when compared with neutral protamine Hagedorn insulin, many patients with diabetes still experience unacceptable glycemic control, in part owing to limitations in insulin therapy, such as hypoglycemia risk, weight gain and the need for patients to adjust their lifestyle to their insulin therapy. Insulin degludec, appropriately labeled as an ultra-long-acting basal insulin, promises to achieve similar blood glucose control to currently available preparations (glargine and detemir insulin), with a reduced risk of hypoglycemia and greater flexibility in the day-to-day timing of insulin administration. Greater flexibility in basal insulin administration and/or reducing hypoglycemia risk in insulin-requiring patients with Type 1 or 2 diabetes may facilitate insulin management for patients and physicians.
