What is a common characteristic of very long acting insulin?

Very long-acting insulin is specifically designed to provide a sustained release of insulin into the bloodstream over an extended period, typically lasting up to 24 hours or more. This characteristic of long duration is key in managing blood glucose levels, as it helps to maintain stable insulin coverage without the peaks and troughs associated with shorter-acting insulins.

This prolonged effect makes very long-acting insulins particularly useful for providing a baseline level of insulin to help control blood sugar levels throughout the day and night, minimizing the risk of high or low blood sugar episodes. This sustained activity aligns with the needs of individuals who require consistent insulin management due to diabetes.

In contrast, very long-acting insulins do not typically exhibit a fast onset or immediate effect, nor do they have peak times of action that define the behavior of shorter-acting insulins. The absence of a pronounced peak helps in avoiding fluctuations in blood glucose levels, making these insulins effective for stable long-term diabetes management.
