What is the typical duration for Ultralente insulin?

Ultralente insulin is known for its long duration of action, typically lasting between 24 to 36 hours. This extended duration makes it effective for covering insulin needs over a longer period, helping to maintain blood glucose levels in people with diabetes. It is a type of long-acting insulin that is often used for basal insulin coverage, allowing patients to manage their insulin levels throughout the day and night with fewer injections.

While the other options suggest shorter durations, they do not adequately encompass the full action time of Ultralente insulin. The typical usage and pharmacokinetics of Ultralente solidify its categorization as a long-acting insulin, justifying the duration of 24-36 hours as the most accurate representation of its effectiveness.
