Wissenswertes über "Basal Insulin"
Basal insulin is a long-acting form of insulin that covers the body´s background insulin needs over 24 hours. It is used in the treatment of type 1 and type 2 diabetes.
What Is Basal Insulin?
Basal insulin is a type of insulin with an extended duration of action, designed to mimic the continuous, low-level insulin release that the healthy pancreas provides around the clock. This background secretion keeps blood glucose levels stable between meals and overnight. When the pancreas can no longer perform this function adequately, basal insulin is used to replace it.
Indications
Basal insulin is used in the following conditions:
- Type 1 diabetes: Since the pancreas produces little or no insulin, basal insulin is an essential component of treatment.
- Type 2 diabetes: When oral medications and lifestyle changes are no longer sufficient to control blood glucose, basal insulin may be added to the treatment plan.
- Gestational diabetes: In certain cases, basal insulin may be required during pregnancy to manage blood glucose levels safely.
Mechanism of Action
Basal insulins are formulated to be absorbed slowly and steadily from the injection site, providing a consistent, flat insulin level in the blood over an extended period. Different formulations achieve this in different ways:
- NPH insulin (Neutral Protamine Hagedorn): An intermediate-acting insulin that is delayed in its release by binding to protamine. It has a duration of approximately 12 to 18 hours and is typically injected twice daily.
- Long-acting insulin analogues: Modern basal insulins such as insulin glargine (e.g., Lantus, Toujeo), insulin detemir (e.g., Levemir), and insulin degludec (e.g., Tresiba) offer a duration of action up to 24 hours or beyond, often allowing once-daily administration.
Dosage and Administration
Basal insulin is typically injected once daily subcutaneously (under the skin), although NPH insulin is often given twice daily. Injection sites are rotated across the thighs, abdomen, and buttocks to prevent tissue changes. The exact dose is determined and regularly adjusted by the treating physician based on individual blood glucose monitoring.
As part of a basal-bolus regimen, basal insulin is complemented by short-acting bolus insulin taken at mealtimes, providing comprehensive blood glucose control throughout the day.
Side Effects
Like all insulins, basal insulin can cause side effects. The most important ones include:
- Hypoglycemia (low blood sugar): The most common and potentially serious side effect, especially if the dose is too high or meals are skipped.
- Lipohypertrophy: Thickening of fatty tissue at injection sites when the same spot is used repeatedly.
- Weight gain: May occur with long-term insulin therapy.
- Local reactions: Redness, swelling, or itching at the injection site.
Important Notes
Basal insulin must never be administered intravenously. It should be stored in a cool place but must not be frozen. Once opened, pens or vials are generally stable at room temperature for 4 to 6 weeks, depending on the manufacturer. Patients should monitor their blood glucose regularly and be familiar with the signs of hypoglycemia.
