Molecular structure of Insulin Glargine

Insulin Glargine, commonly known under the brand name Lantus, is a long-acting insulin analog used to control blood sugar levels in patients with diabetes. This laboratory-made hormone is designed to provide more consistent blood sugar control compared to regular insulin.

Overview

Insulin Glargine is a recombinant form of insulin, used primarily for the management of Type 1 and Type 2 diabetes. It helps in regulating the metabolism of carbohydrates, fats, and proteins by promoting the absorption of glucose from the blood into liver, fat, and skeletal muscle cells.

Chemical Structure and Function

Insulin Glargine differs from human insulin in its amino acid sequence, which results in a lower solubility at physiological pH. This feature allows for a slower and more predictable absorption rate, ensuring a consistent insulin level for a longer period.

Clinical Use

Indications

• Management of Type 1 diabetes
• Management of Type 2 diabetes, particularly in cases where blood sugar is not adequately controlled by oral antidiabetic drugs

Administration

• Administered via subcutaneous injection
• Typically used once daily, often at bedtime

Comparisons with Other Insulins

Compared to short-acting insulin, Insulin Glargine provides a more stable, peakless, and prolonged insulin release, reducing the risk of nocturnal hypoglycemia.

Side Effects and Precautions

While generally well-tolerated, Insulin Glargine may cause side effects such as:

• Hypoglycemia (low blood sugar)
• Injection site reactions
• Allergic reactions in rare cases

Patients should monitor blood sugar levels regularly and adjust the dose under medical supervision.

Pharmacological Classification

Insulin Glargine is classified as a long-acting insulin analog and falls under the category of therapeutic insulin.

Development and Approval

Developed by Sanofi-Aventis, Insulin Glargine was first approved for medical use in the United States in 2000. Since then, it has become a widely used insulin analog worldwide.
