What is the peak duration for long acting insulin?

The peak duration for long-acting insulin typically falls within the range of 8-20 hours. Long-acting insulin formulations, such as insulin glargine and insulin detemir, are designed to provide a steady and consistent release of insulin to help regulate blood glucose levels over an extended period, which is crucial for managing diabetes.

The concept of "peak duration" refers to the time at which the insulin reaches its maximum effectiveness in lowering blood glucose levels. For long-acting insulins, this period extends beyond just a few hours and is intended to provide a basal level of insulin, thereby reducing the need for additional short-acting insulins or frequent dosing throughout the day.

This extended action is beneficial for individuals who require stable blood sugar management, especially overnight or between meals. Choosing a duration of action like 8-20 hours reflects the pharmacokinetics of these insulin types, allowing for both flexibility and the maintenance of glycemic control.
