Lantus

Lantus, known generically as Insulin Glargine, is a sophisticated long-acting insulin meticulously crafted to regulate blood sugar levels in those with diabetes mellitus. It is frequently prescribed for both type 1 and type 2 diabetes, offering a consistent and extended therapeutic effect.

Applications

Type 1 Diabetes:

Administered alongside rapid- or short-acting insulins to replicate the natural secretion of insulin.

Type 2 Diabetes:

Utilized independently or in conjunction with oral antidiabetic agents or other injectable diabetes treatments.

Mechanism of Action

Lantus is an advanced basal insulin analog, engineered to release insulin gradually over a 24-hour period, thereby ensuring stable blood glucose levels. It emulates the basal insulin secretion characteristic of a healthy pancreas in non-diabetic individuals.

How It Functions

Insulin glargine is uniquely modified to exhibit low solubility at physiological pH. Upon subcutaneous injection, it forms microprecipitates that allow for the slow release of insulin into the bloodstream. This results in a smooth insulin effect with minimal peaks, significantly lowering the risk of hypoglycemia.

Dosage and Administration

General Recommendations:

Lantus is to be administered once daily at a consistent time, irrespective of meal schedules.

Dosage is tailored to individual needs based on blood glucose monitoring.

Initial Dosage:

Type 1 Diabetes: Typically, 1/3 to 1/2 of the total daily insulin requirement.

Type 2 Diabetes: The starting dose is generally 10 units per day or adjusted according to body weight (e.g., 0.2 units/kg).

Injection Sites:

Administered subcutaneously in the abdomen, thigh, or upper arm, with rotation of sites to prevent lipodystrophy.

Important: Lantus must not be mixed with other insulins or solutions.

Onset, Peak, and Duration

Onset: Approximately 1 to 2 hours.

Peak: Generally minimal or absent.
