What is the peak time for Ultralente insulin?

The peak time for Ultralente insulin is indeed between 18-24 hours. This long-acting insulin formulation provides a stable and extended duration of action, making it effective for controlling blood glucose levels over a prolonged period. Ultralente is designed to release insulin gradually into the bloodstream, which helps manage blood sugar levels consistently throughout the day, particularly for patients who require a long-lasting basal insulin.

The duration and peak of Ultralente insulin differ significantly from other insulin types. For example, rapid and short-acting insulins peak much sooner—between 1-2 hours or around 6-14 hours—making them less suitable for achieving the prolonged coverage that Ultralente provides. Furthermore, some long-acting insulins may have a different pharmacokinetic profile that leads to even longer durations, but Ultralente specifically has its peak action established within the 18-24 hour range. Understanding this peak time is crucial for designing effective insulin regimens and ensuring optimal glucose control for patients.
