Introduction to Rapid-Acting Insulin Analogs
Definition and Purpose of Rapid-Acting Insulin
Rapid-acting insulin analogs are special insulin types. They work faster than regular insulin. They help control blood sugar levels, especially after meals.
Role in Diabetes Management
Rapid-acting insulin is key in managing diabetes. It helps control blood sugar levels. It also makes it easier to adjust insulin plans to fit individual needs.
Studies show that these insulins help keep blood sugar stable. They also lower the chance of blood sugar dropping too low.
A study looked at 2,751 people with type 2 diabetes. It compared short-acting insulin analogs to regular insulin. The results showed no big difference between the two.
The GEMELLI 1 study involved 597 people with type 1 or 2 diabetes. It found that SAR-Asp, a new rapid-acting insulin, works well. It’s safe and effective for those who have used other insulins before.
“Rapid-acting insulin analogs help individuals with diabetes achieve better blood glucose control, reduce postprandial glucose excursions, and minimize the risk of hypoglycemia.”
Insulin Lispro (Liprolog)
Pharmacological Properties
Insulin lispro, known as Liprolog, is a fast-acting insulin. It works like the body’s natural insulin. It starts working in 15 minutes after being injected under the skin.
Its peak effect happens 30 to 90 minutes later. This quick action lasts about 5 hours. It’s great for controlling blood sugar after meals.
Dosing and Administration
Adults and kids with diabetes use insulin lispro. It helps control blood sugar levels. The starting dose is 0.4 to 0.5 units per kilogram of body weight per day.
For type 1 diabetes, the usual dose is 0.4 to 1 unit per kilogram per day. This is split into several doses throughout the day.
Type 2 diabetes starts with 4 to 6 units or 10% of the basal insulin dose. For high blood sugar, doses can go up by 1 to 2 units or 10% to 15% every 3 days. For low blood sugar, doses can be lowered by 10% to 20% for mild cases and 20% to 50% for severe cases.
Take insulin lispro right before a meal. Adjust the dose based on blood sugar levels and meal size. This helps reach the right blood sugar target.
| Characteristic | Insulin Lispro (Liprolog) |
|---|---|
| Onset of Action | 10-20 minutes |
| Peak Effect | 1-2 hours |
| Duration of Action | 2-5 hours |
“Insulin lispro has a more rapid onset of action and a shorter duration of activity than regular human insulin when given subcutaneously.”
Insulin Aspart (Novolog)
Insulin aspart, sold as Novolog, is similar to insulin lispro (Liprolog). It works fast to control blood sugar after meals. It starts working in 10-20 minutes, peaks in 1-2 hours, and lasts for 2-5 hours.
Novolog is quickly absorbed, which means it starts working fast. This makes it great for controlling blood sugar after eating. You can take it right before or after a meal.
“Novolog’s rapid-acting properties allow it to closely mimic the body’s natural insulin response, making it an effective tool for managing diabetes and maintaining tight glycemic control.”
Studies show Novolog is as good as other fast-acting insulins like Liprolog. Both help lower blood sugar levels and control them after meals.
Novolog is easy to use because you can adjust your dose. This is helpful if you eat different amounts or exercise a lot. Its fast action lets you adjust your insulin dose more precisely.
