Which insulin type is used for long-term management of diabetes and does not peak?

Lantus insulin, also known as insulin glargine, is designed for long-term management of diabetes due to its unique pharmacokinetic profile. It is a long-acting insulin that provides a steady release of insulin over an extended period, typically lasting up to 24 hours. Unlike other insulin types that have distinct peaks, Lantus has a flat action profile, meaning that it does not exhibit pronounced peaks in its activity. This characteristic allows for more stable blood glucose levels throughout the day and reduces the risk of hypoglycemia, making it ideal for maintaining basal insulin levels in individuals with diabetes.

This consistency and prolonged duration of action make Lantus particularly well-suited for patients needing a reliable long-term insulin regimen without the fluctuations that can accompany insulins that peak at certain times. Other insulin types, such as regular insulin, lispro insulin, and NPH insulin, have specific peak times when their effects are most pronounced, which may not provide the same level of stable glucose control as Lantus.
