Which long-acting insulin is commonly known as Lantus?

Lantus is the brand name for insulin glargine, a long-acting insulin used to manage blood glucose levels in individuals with diabetes. Insulin glargine is characterized by its ability to provide a steady level of insulin over an extended period, typically up to 24 hours, making it an important option for patients who require consistent blood glucose control.

When injected, insulin glargine forms microprecipitates in the subcutaneous tissue, which allows for a slow and even release into the bloodstream, helping to manage blood sugar levels throughout the day and night. This is particularly beneficial for maintaining basal insulin requirements without the peaks and troughs associated with short-acting insulins or premixed formulations.

Other options mentioned are different types of insulin. Insulin detemir is another long-acting insulin but is not Lantus. NPH insulin (neutral protamine Hagedorn) is an intermediate-acting insulin with distinct pharmacokinetics and is typically administered multiple times a day. Regular insulin refers to short-acting insulin, which is used primarily for mealtime coverage rather than long-term basal needs.

The key distinction for Lantus lies in its formulation and mechanism that enables prolonged action, differentiating it clearly as
