Which type of insulin is known as rapid-acting?

Lispro (Humalog) is classified as a rapid-acting insulin, making it effective in controlling postprandial blood glucose levels. Its onset of action is typically within 15 minutes of injection, with peak effects occurring around 1 to 2 hours later and a duration of action of approximately 3 to 5 hours. This rapid onset and quick peak make it particularly useful for managing blood sugar spikes that occur after meals.

In pediatric care, rapid-acting insulins like Lispro are frequently used to provide flexibility in timing of meals and to allow for more precise dosing with regard to carbohydrate intake, which is crucial in managing diabetes in children. It can be administered just before or even as a meal is being eaten, offering convenience and improved control of blood glucose levels.

NPH (Humulin N) is an intermediate-acting insulin that takes longer to kick in and lasts longer than rapid-acting insulins, making it less suitable for immediate post-meal glucose control. Similarly, Regular (Humulin R) is a short-acting insulin, effective, but not as rapid as Lispro, with a longer onset time. Glargine (Lantus) is a long-acting insulin that provides a steady release of
