What is the duration of premixed insulin action?

The duration of action for premixed insulin typically falls within the range of 16 to 24 hours. This type of insulin combines both fast-acting and intermediate-acting components, providing a dual action that covers both mealtime glucose spikes and longer-term glucose control.

The fast-acting component starts to work quickly to manage blood sugar levels during meals, while the intermediate-acting component maintains glucose control for several hours extending beyond the meal period. The 16-24 hour duration is effective for many individuals requiring basal and prandial (mealtime) insulin management.

This characteristic duration is essential for clinicians and patients to understand because it directly impacts the timing of doses in relation to meals and activities, ensuring optimal management of blood glucose levels throughout the day.
